8 Bible Verses about Division Among Christians

Certain men [i.e., believers, see verse 5] came down from Judea [to Antioch of Syria] and began teaching the brothers this: You cannot be saved unless you are circumcised according to the custom [required] by Moses. After Paul and Barnabas had a heated debate and argued with these men [over this issue], the brothers [of the Antioch church] decided that Paul and Barnabas, along with certain others, should go up to Jerusalem and discuss the question with the apostles and elders there. So, they were sent on their way with the backing of the [Antioch] church and traveled through both Phoenicia and Samaria, telling them about the conversion of the Gentiles. This brought great rejoicing to all the brothers [who heard about it].read more.
When they arrived in Jerusalem they were welcomed by the church, together with the apostles and elders, and then reported everything that God had done through their ministry. But certain believers, [who had been] members of the sect called Pharisees [i.e., a strict sect of the Jewish religion], began saying, "It is necessary to circumcise people [see verse 1] and require them to keep [the ordinances of] the law of Moses."

Now I urge you, brothers, watch out for those who are causing divisions and occasions for falling [away from God over matters] contrary to the teaching you have learned, and withdraw from them [i.e., stop listening to their false teaching].

Now I urge you, brothers, through the name [i.e., by the authority] of our Lord Jesus Christ, that you should all agree in what you say, so that no divisions [continue] among you. Be restored [to unity] by having common thoughts and convictions [i.e., in spiritual matters]. For it has been reported to me about you, my brothers, by some of Chloe's family, that there is quarreling [going on] among you. Now this is what I mean: Each of you is saying, "I am a follower of Paul," and another "I am a follower of Apollos," and another "I am a follower of Cephas [i.e., Peter]," and another "I am a follower of Christ."read more.
Has Christ been divided? Was Paul crucified for you? Or were you immersed into the name of Paul?

for you are still worldly [minded]. And since there is jealousy and quarreling among you, is that not evidence that you are [still] worldly and living like [unspiritual] people?

If any one of you has a complaint against someone, how can you dare to take it before non-Christian judges [to be decided], instead of before the saints [i.e., God's holy people]?

For first of all, I have been informed [Note: This was probably by Chloe's family. See 1:11] that divisions exist among you people when you assemble as a congregation. And I am inclined to believe it [is true].

Watch out for the "dogs!" [Note: "Dogs" were viewed with disgust by the ancient Jews (Deut. 23:18; II Kings 8:13; Rev. 22:15), so the term is used here derogatorily for Jewish Christians who were trying to impose on the church the requirements of the law of Moses]. Watch out for the evil workers! Watch out for those who mutilate the body meaninglessly! [Note: Paul here alludes, in a derogatory wordplay, to the Jewish practice of circumcision].

These antichrists left our group [i.e., withdrew their fellowship from us], but they were not [really a part] of us, for if they had been, they would have continued [to participate] with us. But, by their leaving us, it proved that none of them were [really] a part of our group [after all].
