Whoever does the will of Our Father in heaven, is Christ’s brother, sister and mother.
(Matt 12:50) “For whoever does the will of My Father in heaven is My brother and sister and mother.”
This is why, Christians are referred as Brothers and Sisters in Christ. Also, throughout the letters in New Testament we see the brotherly love written over and over again.
(Heb 13:1) Let brotherly love continue.
(Rom 12:10) [Be] kindly affectionate to one another with brotherly love, in honor giving preference to one another;
(1Pet 2:17) Honor all [people.] Love the brotherhood. Fear God. Honor the king.
However, Bible also teaches to keep away from some people who call themselves as brothers in Christ. We are also told not even to pray for such people.
(1Cor 5:11) But now I have written to you not to keep company with anyone named a brother, who is sexually immoral, or covetous, or an idolater, or a reviler, or a drunkard, or an extortioner — not even to eat with such a person.
How strong can this message be from Paul so that you need to get away from such name Christians? He didn’t stop there. Paul, Silvanus, and Timothy, in their letter to the church of the Thessalonians, warned to withdraw from every brother who walks disorderly.
(2Thess 3:6) But we command you, brethren, in the name of our Lord Jesus Christ, that you withdraw from every brother who walks disorderly and not according to the tradition which he received from us.
(2Thess 3:10-11) For even when we were with you, we commanded you this: If anyone will not work, neither shall he eat. For we hear that there are some who walk among you in a disorderly manner, not working at all, but are busybodies.
(2Thess 3:14-15) And if anyone does not obey our word in this epistle, note that person and do not keep company with him, that he may be ashamed. Yet do not count [him] as an enemy, but admonish him as a brother.
(Matt 18:15-17) ” Moreover if your brother sins against you, go and tell him his fault between you and him alone. If he hears you, you have gained your brother. “But if he will not hear, take with you one or two more, that ‘by the mouth of two or three witnesses every word may be established.'”And if he refuses to hear them, tell [it] to the church. But if he refuses even to hear the church, let him be to you like a heathen and a tax collector.
John goes one step further to not even pray for a brother in Christ who is committing a sin that leads to death.
(1John 5:16-17) If anyone sees his brother sinning a sin [which does] not lead to death, he will ask, and He will give him life for those who commit sin not leading to death. There is sin leading to death. I do not say that he should pray about that. All unrighteousness is sin, and there is sin not leading to death.
The question is, are you obeying the Bible in getting away from name-Christians? Or are you yourself a name-Christian? Repent!
