"I exhort you, brethren, by the name of our Lord Jesus Christ, that you all agree and that there be no divisions among you..."
The Division in which he speaks:
1 Corinthians 1:13
"Has Christ been divided?"
Believers at Corinth claimed to be of a certain 'sect' under Christ: 'of Paul', 'of Apollos', 'of Cephas'. Christ has not been divided. Let us as believers at least agree that we are not of a certain sect under Christ, but that we are under Christ and Christ alone.
Other verses I think of:
1 Corinthians 11:3
"But I want you to understand that Christ is the head of every man, and the man is the head of a woman, and God is the head of Christ."
Romans 14:4
"Who are you to judge the servant of another? To his own master he stands or falls; and he will stand, for the Lord is able to make him stand."
Matthew 15:3
"And He answered and said to them, "Why do you yourselves transgress the commandment of God for the sake of your tradition?"
