Division (Differences) Among Christians Is Also Wrong
I Corinthians 1:10 is many times correctly used by brethren to prove denominationalism is wrong, that such religious division is sinful. But did you ever notice that verse is written to and about brethren? Here is the text - "Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfectly joined together in the same mind and in the same judgment."On a number of occasions I've heard mature Christians indicate that when denominational people don't believe and practice the truth on things such as baptism, the Lord's Supper, and etc., they will be lost because of that, but that differences among conservative brethren won’t cause people to be lost. That's a double standard if I've ever seen one.Yes God also expects Christians to "all speak the same thing" (teach the truth) just as much as he expects denominational people to do so. It is not optional for anybody. To condemn those "outside my group" for not practicing the truth (James 2:10), but not do the same for those "in my group" is doing exactly what Matt 7:1ff ("Judge not, that ye be not judged") is condemning - hypocritical judging.We all must abide in the "doctrine of Christ" to have God (II John 9) - regardless of what church we belong to. If two gospel preachers (Christians) are teaching two different things (say like on I Cor 11:2-16), they both can’t be right. We must continue in God’s word and stand for the truth on every Bible topic in order to be set free from sin (John 8:31-32), not just topics that members of churches of Christ agree on.
