Did the Apostles break fellowship with those who were teaching different doctrines than they were teaching?

Answer 1

2 John 9-11....Everyone that pushes ahead and does not remain in the teaching of the Christ does not have God. He that does remain in this teaching is the one that has both the Father and the Son.  If anyone comes to YOU and does not bring this teaching, never receive him into YOUR homes or say a greeting to him. For he that says a greeting to him is a sharer in his wicked works.

(2 Thessalonians 3:14) But if anyone is not obedient to our word through this letter, keep this one marked, stop associating with him, that he may become ashamed.

Answer 2

It would appear that they did.

Galatians 1:8 But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let him be eternally condemned! 9 As we have already said, so now I say again: If anybody is preaching to you a gospel other than what you accepted, let him be eternally condemned!

1 Timothy 1:18 Timothy, my son, I give you this instruction in keeping with the prophecies once made about you, so that by following them you may fight the good fight, 19 holding on to faith and a good conscience. Some have rejected these and so have shipwrecked their faith. 20 Among them are Hymenaeus and Alexander, whom I have handed over to Satan to be taught not to blaspheme.

2 John 1:7 Many deceivers, who do not acknowledge Jesus Christ as coming in the flesh, have gone out into the world. Any such person is the deceiver and the antichrist. 8 Watch out that you do not lose what you have worked for, but that you may be rewarded fully. 9 Anyone who runs ahead and does not continue in the teaching of Christ does not have God; whoever continues in the teaching has both the Father and the Son. 10 If anyone comes to you and does not bring this teaching, do not take him into your house or welcome him. 11 Anyone who welcomes him shares in his wicked work.

Titus 3:9 But avoid foolish controversies and genealogies and arguments and quarrels about the law, because these are unprofitable and useless. 10 Warn a divisive person once, and then warn him a second time. After that, have nothing to do with him.

Answer 3

Yes. Paul continually warned people in his letters about differences. Jesus likewise in His preaching and teaching said to have no fellowship with the works of darkness or to go after other Christs. He spoke of Satan sifting the Church, but called on the Apostles, Peter in particular, to remain faithful.

Answer 4

I don't know if fellowship was broken but the apostles did write letters to certain groups rebuking them of their teaching wrong doctrine.

Answer 5

Outside of the church assembly yes.However in order to preserve the purity and doctrine of the early church no one was allowed to preach doctrine contrary to Biblical teachings in the church.All christians do not hold the same beliefs such as predestination,limited atonement etc.

Answer 6

Yes, Absolutely
