1 Corinthians 1:10-11

But I urge you, believers, by the name of our Lord Jesus Christ, that all of you be in full agreement in what you say, and that there be no divisions or factions among you, but that you be perfectly united in your way of thinking and in your judgment [about matters of the faith]. For I have been informed about you, my brothers and sisters, by those of Chloe’s household, that there are quarrels and factions among you.
