I refer you to these scriptures.
2 Thessalonians 3:6
In the name of the Lord Jesus Christ, we command you, brothers, to keep away from every brother who is idle and does not live according to the teaching you received from us.
I urge you, brothers, to watch out for those who cause divisions and put obstacles in your way that are contrary to the teaching you have learned. Keep away from them.
1 Corinthians 5:10-13 (New International Version)
10 not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters. In that case you would have to leave this world. 11 But now I am writing you that you must not associate with anyone who calls himself a brother but is sexually immoral or greedy, an idolater or a slanderer, a drunkard or a swindler. With such a man do not even eat.
12 What business is it of mine to judge those outside the church? Are you not to judge those inside? 13 God will judge those outside. "Expel the wicked man from among you." [a]
2 Thessalonians 3:14
If anyone does not obey our instruction in this letter, take special note of him. Do not associate with him, in order that he may feel ashamed.
The anointed in the early Christians held each other up to rebuke and expelling if they ignore their teachings or caused divisions among many other things. Are you saying this was wrong of the early Christians?
