1 Corinthians 1:10 – 13
New International Version (NIV)
A Church Divided Over Leaders
10 I appeal to you, brothers and sisters, in the name of our Lord Jesus Christ, that all of you agree with one another in what you say and that there be no divisions among you, but that you be perfectly united in mind and thought. 11 My brothers and sisters, some from Chloe's household have informed me that there are quarrels among you. 12 What I mean is this: One of you says, “I follow Paul”; another, “I follow Apollos”; another, “I follow Cephas”; still another, “I follow Christ.”
13 Is Christ divided? Was Paul crucified for you? Were you baptized in the name of Paul?
