In the Bible, “brothers in Christ” refers to all people who have trusted in Jesus Christ and have therefore been adopted into the family of God. Christians are not merely connected by shared interests, culture, nationality, or religious activity; through the Father’s electing work, the Son’s redemptive work, and the Spirit’s regenerating work, they are objectively united as members of one spiritual family.
The expression also points to a practical relationship. Brothers and sisters in Christ are called to love one another, pursue unity and reconciliation, offer spiritual and material help, pray for one another, gather for worship, and share life together as members of the household of God. The biblical meaning of “brother” is therefore both theological and relational: believers belong to the same family because they belong to Christ.
What does “brothers in Christ” mean?
There are many definitions of a brother found in the dictionary. It can mean a male of the same parentage. It can also be someone who is related by common interests or a close male friend or comrade. The one definition that Webster left out was that of a true brother in Christ.
A true brother will always have faults and struggles, but he comes along beside us and help us to strive, reach, and attain higher ground especially when we are struggling. He is someone who you trust and feel safe with -- someone who you are accountable to because there is respect, integrity, and honesty.
Most fundamentally, Christians relate to one another as brothers and sisters. At the most basic level of our relationships with one another, we are marked by a unique, familial bond.
“Brother in Christ” is an appellation referring to the specifically Christian unity, of which Christ Himself is the center and criterion.
Why Christians are called brothers and sisters
On the basis of the atoning work of Christ on behalf of His people, all those who are united to the Son by faith have been adopted into the family of our Heavenly Father (cf. Gal 3:26; 4:5). And what a wonderful picture of the fellowship that believers in Jesus have with one another: to be brothers and sisters of the same family!
When we take Christ as Savior we are immediately justified, and we immediately have a new relationship with God the Father, God the Son, and God the Holy Spirit. When we come into this new relationship with the triune God, all those who have ever trusted Christ as their Savior are our brothers and sisters.
This has been usually spoken of as “the communion of saints.” Before we took Christ as our Savior, we were strangers and foreigners. But when we became Christians, we were made fellow-citizens and members of God’s household with all others who had done the same.
Our relationship to one another is not based upon common interests or shared hobbies. We’re not merely a social club or a political organization linked by superficial commonalities.
We are objectively united to one another, by virtue of the electing work of the Father (Eph 1:5), the redemptive work of the Son (Gal 4:5), and the regenerating work of the Spirit (Rom 8:15). We’re a family.
“Brother” in the New Testament
This designation dominates Paul’s thinking throughout his letters, especially in this letter to the Philippians. He addresses them as brethren six other times (1:12; 3:1, 13, 17; 4:8, 21).
Although it’s well-used, it’s anything but just some sort of filler-word for the Apostle Paul. Sometimes I get the impression that we’ve begun to treat the term “brother” or “sister” as a sort of throw-away word, evacuated of all of its meaning.
But it wasn’t like that for Paul. He used the term purposefully, knowing that it would engender tenderness and affection from his readers by reminding them of their spiritual union in belonging to the family of God.
The early Christians soon adopted the term brother as their usual mode of addressing one another (30 times in Acts and 130 times in Paul), and the name remained in common use among Christians in general until late in the 3d century, when its use was gradually restricted to clerical and monastic circles.
Who is included in the biblical use of “brothers”?
Not all men are brothers, according to the biblical use of that word. We are all created by God. As all are descendants of Adam and Eve, all men are “my kind” and are to be carefully treated as neighbors (Luke 10:27-37).
But in the terms of the Bible, we are brothers to those who have Christ as their Savior and therefore have God as their father. We are to do good to all men, but there is a clear line between the “family of believers” and others.
A person cannot have true spiritual fellowship with Christians until he has heard the facts of the gospel and has acted upon those facts by accepting Christ as his Savior. The brethren are defined as those who hold to the testimony of Jesus.
Judas, who did not believe on Christ, had left the table before this command for special love among Christians was given. It is clear that “brethren” as used here speaks of believers.
Saul was considered a “brother” only after he had taken Christ as his Savior. Only the fellow-believers were “the brothers.” In this passage the man is a believer and therefore a brother. The wife is not a believer and therefore is not included in this term.
Brothers in Christ and the family of God
A family is not merely a group of people with some shared interests and a subjective appreciation for one another. No, brothers and sisters are bound together by something much deeper than that: by the objective union that exists as a result of the love shared by their parents.
And that objective reality that binds us together means that we will always be there for one another. I have two younger brothers, and we’ve had our share of tensions and arguments (and all-out fights). But no matter what happens in our lives, we will never stop being brothers.
That objective bond is unbreakable. And the same is true within the family of God. There may be tensions and disagreements that exist between us and our brothers and sisters in Christ.
But just as nothing can separate us from the loving union that we share with Christ individually, neither can anything separate us from the union that we share with one another, corporately. And so whatever subjective disunity exists between us, we can fight for unity, and reconciliation, and oneness with one another, standing on the solid foundation of our objective unity as children of God.
Jesus as the brother of believers
Scripture speaks of Jesus as our brother in Hebrews 2:11 and Romans 8:29. The brotherhood of Jesus adds weight, wonder, and affection to Christian worship because it joins the exalted uniqueness of Jesus as the Son of God with His condescension to share our human nature and suffering.
Jesus is not our brother in the sense that He is merely another sinner or merely one human being among others. He is the eternal and divine Son of God, the founder of our salvation, the firstborn among many brothers, and the ever-exalted and superior older brother of those whom He saves.
Hebrews 2:11: Jesus is not ashamed to call believers brothers
“For it was fitting that he,” - this is God the Father, - “for whom and by whom all things exist, in bringing many sons to glory, should make the founder,” - so, it was fitting that he should make the founder, that is Jesus, it is fitting that he should make the founder - “of their salvation perfect through suffering.”
So, God thought it fitting, suitable, appropriate, beautiful to complete, to make perfect the beauty of Christ through suffering. And here comes the ground: “because,” verse 11, “because” - “he who sanctifies” - we know that is Jesus, because of the way Hebrews 13:12 refers to he who sanctifies: Jesus, - “he who sanctifies and those who are sanctified” - his emerging sons of God, brothers - “all have one source.”
That is difficult to know what that refers to, but it could be “all of one Father” or “all of one human nature” - they are literally “all of one.” “That is why he is not ashamed to call them brothers.”
So, he is not ashamed to call us brothers, because in bringing us to sanctification through Jesus’s death for us, which was fitting in bringing many sons to glory, therefore he is not ashamed to call us brothers.
The writer is giving a reason for why it was fitting that Christ lead many sons to glory through sufferings. And one great aim of God in salvation is that he have a great, unified family of children with Jesus Christ being both essentially different from, and yet deeply united to, his other human brothers and sisters, both really different and really like.
But if all the brothers and sisters in the family have experienced suffering, except one, then the unity is jeopardized. And so, for the sake of a common spirit of unity and sympathy and camaraderie, even in suffering, Christ takes on human nature and he leads many sons to glory and into his brotherhood through suffering and death.
In other words, the reason it is fitting for Christ to suffer to lead many sons to glory and, thus, many brothers into brotherhood and glory is that this suffering expresses his being a good, beautiful comrade-brother.
All of this hangs on God’s aim to create a family that is so unified and so deeply interwoven and empathetic that the family would be jeopardized, would be undermined, if the perfect oldest brother does not go through all the pain of the rest of the children.
Romans 8:29: the firstborn among many brothers
He says, “For those whom he [God] foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers.”
One purpose of God in predestination is conformity to the image of the Son of God, so that we can actually be called brothers because of this unity, this conformity, this union with Christ. We are brothers by likeness, not just legally, but by likeness to his image.
But the stress also falls on the fact that Jesus is “the firstborn among the brothers.” And that term firstborn should probably have here the complete weight that it had in the Old Testament, like Psalm 89:27, where it says, “And I will make him the firstborn, the highest of the kings of the earth.”
That is not a small word in Paul’s vocabulary. So, the reason this gives weight and wonder to our worship of the Son is, again, the combination of oneness with us as we are conformed to his image and difference from us in being the firstborn in the fullest sense of the highest of the kings of the earth.
Our elder brother is one with us and yet infinitely above us, and it is the conjunction of those two things that is peculiar - I like to say the peculiar glory that we worship.
Believers as fellow heirs with Christ
Being a brother of Christ means being a fellow heir with him. So, Paul says, “The Spirit himself bears witness with our spirit that we are children of God, and if children, then heirs,” - and then he adds - “fellow heirs with Christ.”
That is what brothers are. They are fellow heirs with Christ, “provided we suffer with him.” Now, that is simply breathtaking for us poor, weak, sinful, ignorant humans: fellow heirs with the Son of God because we are in the family by “the Spirit of adoption” (Romans 8:15).
God’s estate that we inherit with Jesus is the universe. It is everything that exists, except God. And the implications of this is a weight of worship that should make us humble, joyful worshipers on Sunday, and should make us the most free from materialism - we own everything by inheritance! - free from materialism; radical lives of love.
Jesus’ teaching about His brothers and sisters
There was a crowd around Jesus and they said: Hey, your mother and your brothers are outside, seeking you. In other words, the people that are closest to you that seem to have the closest human ties, they want to talk to you.
Now Jesus’s answer is simply stunning. He says, “‘Who are my mother and my brothers?’ And looking about at those who sat around him, he said, ‘Here are my mother and my brothers! For whoever does the will of God, he is my brother and sister and mother.’”
To be the mother or sister or brother of Jesus means that your intimacy of relationship will be very, very close. There will be privileges. There will be access. There will be protection.
It is wonderful to have a big brother who is strong when you are getting in a fight on the playground. It is wonderful if you are watching your son die to have him care for you and put John in charge of you, because he is a good caregiver to his mother.
You want Jesus to be a good caregiver to you? Then become the mother or the brother of Jesus by obeying the will of God.
The weight and wonder of our worship of Jesus is always a mingling of trembling reverence at the unique divine greatness of the One who is, and the unspeakable lowliness that unites him to us in a shared human nature and suffering and amazingly intimate friendship.
Jesus’ death and resurrection create a new brotherhood
It is by faith and the doing of the Father's will that one becomes a brother of Jesus. By His death and Resurrection Jesus has become in the fullest sense “the firstborn among many brethren,” reconciling divided humanity in His Body on the cross.
It is the risen Lord who calls His Apostles truly His “brothers,” and in them all men without exception. This Christian concept of brotherhood is found in a strongly ecclesial context in Matthew, chapter 18.
Because of the marvelous work accomplished by the Lord Jesus Christ on the cross-because of the sovereign work of God in snatching Paul from the blindness of his Judaism and snatching the Philippians from the blindness of their paganism-and opening all of their eyes to the ugliness of their sin and the unspeakable glory of Jesus, granting to them a common faith in this crucified and risen Lord-they are now brethren; they are now brothers and sisters in Christ.
We are sinners, born under God’s just wrath and condemnation. We are undeserving recipients of the Father’s gracious, electing love. We are rebels for whom the sinless son of God has gone to the cross and rose from the dead in order to pay for our sins and provide our righteousness.
We are hostile enemies overcome by the effectual and irresistible work of the Spirit to grant life and faith in our hearts. And having been justified by that faith that was given to us as a free gift, we have been adopted into the family of God.
Those shared realities far outweigh any worldly differences that exist between us.
The unity of all believers in Christ
“There is neither Jew nor Greek, neither slave nor free man, neither male nor female; for you are all one in Christ Jesus.”
The brotherhood of believers cuts across the lines of nationality, race, language, culture, social position, and geographical location. It also crosses all the lines of time.
This brotherhood includes not just Christians on the earth today, but Christians who are in Heaven. The things which we now have in common with one another as we share in Christ far outweigh any differences between us.
And so no matter what distinctions might exist between you-whether ethnic and cultural backgrounds, levels of education, age and circumstances of life, shared interests and hobbies, and even degrees of spiritual maturity-the reality of our common adoption into the family of God puts us all on a level.
There’s no room in the family of God for an attitude that exalts natural, superficial distinctions over and against the supernatural, spiritual unity that belongs to every brother and sister in Christ.
- “Oh, I prefer not to hang out with those people because they don’t understand my cultural heritage.”
- “Because they’re so much younger or older than me.”
- “Because they don’t have young children and I’m at the stage of life where I need people who are sharing my experiences.”
The Gospel trumps all of that!
What brothers and sisters in Christ should do for one another
There are three practical aspects of the brotherhood of believers. The first practical aspect is that brothers in Christ should be a spiritual help to each other.
Spiritual help and mutual growth
Christians should love one another and should desire the advancement of their brothers above their own advancement. Christians should sorrow when other Christians suffer, and should rejoice when other Christians have joy.
Christian brothers are to pray for each other. Christians should pray for each other and for all Christians.
When individual Christians become what they should be, the Church becomes what it should be. Each Christian has something to contribute to this.
The brotherhood of believers should be the predominant factor between Christians in all the relationships of life. This is true of husbands and wives, children and parents, servants and masters, employees and employers.
In all such relationships we are also brothers and sisters. See Song of Solomon 4:9, 10, 12-there is a double relationship of sister and bride.
The two great spiritual helps which brothers in Christ should be to each other are that of encouraging one another and edifying one another. The latter means helping other Christians to be what they should be in doctrine and life.
Material help and hospitality
The second practical aspect is that brothers in Christ should be a material help to each other. From the earliest days of the Church, Christians gave of their material goods to help those brothers in Christ who had less materially, even those at great geographical distance.
This is one illustration of many examples given in the New Testament of Christians giving money to help other Christians in material need. One form of practical help is by giving hospitality.
There is no use talking about Christian love if we do not help our brothers in Christ when they have material needs. The Christians helped each other materially, but they did it voluntarily.
Each man kept the right of personal property and possession.
Fellowship and companionship
The third aspect is that brothers in Christ should enjoy the fellowship and companionship of each other. From the earliest days of the Church, the Christians had daily fellowship with each other.
True Christians should try to have fellowship together in love and peace. It is the direct command of our Lord that after we have become Christians, we should meet together for worship with other Christians.
This was not just to be a passing thing in the early days of the Church, but should continue even until Christ comes back again. This verse says we should be especially careful to keep this command as we come toward the time of the second coming of Christ.
If we have accepted Christ as our Savior, we have the responsibility to search out a Bible-believing group of God’s people, where there is right doctrine and real community in love, and meet with them.
We should not join ourselves to just any group that calls itself Christian, but one where the teaching is truly biblical, where discipline is maintained concerning life and doctrine, and where there is true community.
If there is no such group geographically available (and there are such places), then prayerfully before the Lord we should find even a small number to meet for worship, prayer, study, encouraging one another, and to have community.
Brotherly love in the body of Christ
To live as a brother is the specifically Christian way to live as a part of the community, to share in its common life. Brothers in Christ must show one another a tender, devoted love modeled on the sacrificial love that Christ showed His own.
Although the love of a Christian brother must take in all men without exception, the visible community of the Christian brotherhood is the special field for that privileged form of love called philadelphia.
The command to love one another is not sentimental or superficial. It is modeled on the sacrificial love that Christ showed His own.
Christians should love one another and should desire the advancement of their brothers above their own advancement. Christians should sorrow when other Christians suffer, and should rejoice when other Christians have joy.
“You’ve got family”: the security of Christian brotherhood
One of the greater blessings during my time in seminary came when there was a potential conflict in my life. I actually don’t remember much at all about what that particular threat was, but I do remember speaking to a then-fellow seminary student about it.
We had gotten to know each other through seminary and because we lived in the same apartment complex. As I spoke with him about whatever it was that was troubling me, he assured me that if I needed his help at all that I could come running, day or night.
And then he looked up at me and said, “You’ve got family.” That really struck me. And it really stuck with me.
Maybe it was especially because my wife and I didn’t have any blood-family out here on the West Coast at the time. But the sense of belonging, and security, and strength in numbers was just so comforting and reassuring to me that I praised God for giving such a loving, familial bond to His children.
Dear reader, that kind of brotherly and sisterly bond needs to mark our relationship with one another in the body of Christ. We need to be able to look at one another in the eye-from the darkest of trials to the smallest of conflicts-and reassure one another that, “You’ve got family,” that “You belong with me, and I’m here for you whenever you need me.”
Differences, conflict, and reconciliation among believers
There may be tensions and disagreements that exist between us and our brothers and sisters in Christ. But just as nothing can separate us from the loving union that we share with Christ individually, neither can anything separate us from the union that we share with one another, corporately.
And so whatever subjective disunity exists between us, we can fight for unity, and reconciliation, and oneness with one another, standing on the solid foundation of our objective unity as children of God.
This Christian concept of brotherhood is found in a strongly ecclesial context in Matthew, chapter 18. Brothers in Christ are called to preserve the fellowship of the church through devoted love, correction, forgiveness, and reconciliation.
The Gospel trumps differences in ethnic and cultural backgrounds, levels of education, age and circumstances of life, shared interests and hobbies, and even degrees of spiritual maturity.
The meaning of brotherhood in Paul’s letter to the Philippians
“Therefore, my brethren, whom I love and long for, my joy and crown, in this way stand firm in the Lord, my beloved.” - Philippians 4:1 -
Before Paul arrives at the crescendo of his exhortation to stand firm in our battle against sin, he couches that exhortation in a flood of the most warmly affectionate and tenderly endearing language found in any of his letters.
And the first term of endearment that Paul uses to designate his relationship with the Philippians is brethren. Most fundamentally, Christians relate to one another as brothers and sisters.
Paul’s language combines affection, responsibility, and spiritual solidarity. The Philippians are not simply an audience receiving instruction; they are beloved members of the same household, people for whom Paul feels joy and toward whom he has a family-like obligation.
That family relationship gives weight to his exhortation to stand firm. Christians endure spiritual conflict not as isolated individuals but as brothers and sisters who belong to one another in the Lord.
Paul and the Philippians: unity across religious and cultural divisions
Remember where Paul was coming from. He was circumcised on the eighth day, of the stock of Israel, of the tribe of Benjamin! A Hebrew of Hebrews and a Pharisee of Pharisees (Phil 3:5-6)!
As Paul penned those words he could remember a time all too clearly when the only thing he would have called the pagan Philippians was uncircumcised dogs. He even would have looked down on Jewish proselytes-and even fellow Israelites who didn’t belong to that strictest sect of the Pharisees.
But because of the marvelous work accomplished by the Lord Jesus Christ on the cross-because of the sovereign work of God in snatching Paul from the blindness of his Judaism and snatching the Philippians from the blindness of their paganism-and opening all of their eyes to the ugliness of their sin and the unspeakable glory of Jesus, granting to them a common faith in this crucified and risen Lord-they are now brethren; they are now brothers and sisters in Christ.
That common faith created a unity deeper than their former identities. Their previous divisions did not disappear as historical facts, but they no longer determined their standing before God or their relationship within the church.
A personal example of the need for a brother in Christ
When I was twelve years old, I went to a church camp where I accepted Christ as my Savior. There were no flashes or chills, just a deep-seated understanding that I was now God’s child.
That deep-rooted knowledge of God’s grace would sustain me through many trials. Although I knew God loved me, I had no one who came beside me as a friend, mentor, or a brother in Christ to teach and prepare me in the ways of the Lord, so I easily fell prey to the offerings of the world.
Our relationship would never be the same. Although he had to start his own life, I felt alone and abandoned heading into the turmoil of my teen years.
It was a critical time in my life. I went off the deep end because no one was there to show me how to become a man. I became accountable to no one and struggled to find my identity.
Because of the pain of losing my father and now my brother, I quickly learned to protect myself by being alone and building walls. In the coming years, I would never let anyone close to me because of the loss of these important people.
I struggled with my idea of who God is and had a hard time trusting in Him. Was it really true what God said in Hebrews 13:5, “Never will I leave you, never will I forsake you”?
The two most important men had left me. Would God leave me too?
The contrast between biological brothers and brothers in Christ
Brothers in Christ are not defined by biological descent, although biological brothers may also become brothers in Christ through faith in Jesus. The spiritual relationship is created by belonging to Christ and sharing God as Father.
In my family, I had two older brothers. My oldest brother James quickly stepped in to fill the vacuum my father had left -- even though he was just a boy himself.
James looked out for the well being and safety of us younger siblings. He was five years older and I became his shadow. He instilled in me many character traits I have carried through life.
My brother was my hero and I looked to him as my compass in life. He was a natural leader, and I always wanted to be just like him.
Biological relationships can provide important care, protection, and influence, but they do not automatically constitute the biblical brotherhood of believers. Conversely, brothers and sisters in Christ may come from entirely different families, nations, cultures, and generations.
Negative influence and the need for spiritual accountability
At the age of 14, I was introduced to pot for the first time by my rebellious brother, Jake. After having a huge argument with our parents, he wanted to get back at them.
I was the target. My innocence left me. I didn’t smoke it very often because I set some limits.
Even though it seemed like I was out of control, there were lines that I would not cross because I knew they would be destructive and when crossed, I would go too far. I saw my brothers “friends” destroying their lives with hard drugs and it scared me away from that scene.
I soon learned to enjoy the taste of my brother’s home-brewed hooch, so alcohol quickly became my sedative of choice. By the time I hit the high school scene, I was ready for action, especially when I got wheels.
To cover the pain, I became the life of the party, but I was still alone and the walls that I had built were getting higher. All of the teachers wondered what had happened to me and why I wasn’t like my brother James.
I wasn’t his shadow anymore. I was on my own. I remember crying out in my soul for my parents, or anyone, to show that they cared.
It was a graceless and lifeless form of Churchianity to me. It was law upon law, rule upon rule. Be good, and make God happy -- whatever that meant.
I couldn’t live that way. I remember thinking that it would be better to party and live the way that I wanted, than live in that stiff lifeless religion.
I wanted life, God’s life, but I didn’t know how to get there. There was a still and silent place in my heart that I knew God had made and He was longing to meet me there.
I was crying out for a brother in Christ, someone who I could trust and feel safe with, to come along beside me. I would have given up everything and anything for that.
The worldly ways I was following meant nothing to me, they were just salve in my deep wounds. I have always asked tough questions about life and they were not being answered.
The church was afraid of my questions. They kept telling me what to believe and that was enough. I kept asking why I should believe.
To me, the answers would lead me to know His personal love in a deeper way.
The brotherhood of believers and the local church
In meditating on John 17, and the emphasis that Christ places on the ‘oneness’ of His redeemed, my heart is reminded of the great importance of the local assembly of saints.
The church, despite all our personal flaws and failings, is a marvelous creation of God. When we come into this new relationship with the triune God, all those who have ever trusted Christ as their Savior are our brothers and sisters.
From the earliest days of the Church, the Christians had daily fellowship with each other. True Christians should try to have fellowship together in love and peace.
If we have accepted Christ as our Savior, we have the responsibility to search out a Bible-believing group of God’s people, where there is right doctrine and real community in love, and meet with them.
The church is therefore not an optional social setting for Christians who happen to share religious interests. It is the visible community in which the family relationship created by Christ is expressed through worship, teaching, prayer, service, discipline, hospitality, encouragement, and mutual care.
How the phrase applies to daily Christian life
To call someone a brother or sister in Christ is to recognize that person as a fellow child of God, a fellow recipient of grace, a fellow member of Christ’s body, and a fellow heir with Christ.
It means that Christians should not treat one another as strangers, competitors, or isolated consumers of religious services. They should regard one another as family members whose spiritual and material welfare matters.
- Brothers and sisters in Christ encourage one another.
- Brothers and sisters in Christ help one another grow in doctrine and life.
- Brothers and sisters in Christ pray for one another.
- Brothers and sisters in Christ share one another’s sorrow and joy.
- Brothers and sisters in Christ provide material help when there is genuine need.
- Brothers and sisters in Christ offer hospitality and companionship.
- Brothers and sisters in Christ pursue unity, peace, and reconciliation.
- Brothers and sisters in Christ gather for worship and fellowship.
The brotherhood of believers should be the predominant factor between Christians in all the relationships of life. Each Christian has something to contribute to this.
Key biblical distinctions
| Relationship | Biblical meaning |
|---|---|
| All human beings | All are created by God and should be treated as neighbors. |
| Brothers and sisters in Christ | Those who have Christ as Savior and therefore have God as their Father. |
| Jesus and believers | Jesus is the divine Son, the firstborn among many brothers, and believers are united to Him through faith and adoption. |
| The local church | The visible community in which the spiritual family shares worship, love, service, and mutual care. |
Scriptural themes behind “all brothers in Christ”
The expression is connected with adoption into God’s family, union with Christ, conformity to Christ’s image, the shared work of the Holy Spirit, fellowship among believers, and the unity of the church.
“There is neither Jew nor Greek, neither slave nor free man, neither male nor female; for you are all one in Christ Jesus.”
We are sinners, born under God’s just wrath and condemnation. We are undeserving recipients of the Father’s gracious, electing love.
We are rebels for whom the sinless son of God has gone to the cross and rose from the dead in order to pay for our sins and provide our righteousness. We are hostile enemies overcome by the effectual and irresistible work of the Spirit to grant life and faith in our hearts.
And having been justified by that faith that was given to us as a free gift, we have been adopted into the family of God. And those shared realities far outweigh any worldly differences that exist between us.
What “all brothers in Christ” does not mean
“All brothers in Christ” does not mean that every person is automatically a spiritual brother or sister simply because every person is created by God. We are all created by God, but in the terms of the Bible, we are brothers to those who have Christ as their Savior and therefore have God as their father.
It does not mean that Christians have no differences, faults, disagreements, or struggles. A true brother will always have faults and struggles.
It does not mean that biological family relationships are irrelevant. Fathers also have a tremendous impact on us, whether positive or not. We learn many things, including problem solving, conflict resolution, and accountability.
It does mean that natural relationships and worldly distinctions cannot be allowed to overthrow the deeper spiritual unity shared by those who belong to Christ.
The biblical pattern of Christian identity
The identity “brother” or “sister” is grounded first in what God has done, not in what believers have accomplished. The Father elects, the Son redeems, and the Spirit gives life and adoption.
Christians are therefore family not because they are naturally compatible, morally superior, or socially similar. They are family because God has brought them into union with Christ.
That union creates both privilege and responsibility. Believers receive belonging, security, access, protection, spiritual inheritance, and fellowship, while also being called to offer love, patience, correction, generosity, prayer, and practical care.
May God grant that we grasp the implications of what it means to be brothers and sisters in Christ.
