Paul was criticized by “superfine apostles,” certainly an equivalent of a modernday apostate of JWs. No, he did not kick them out of the congregation, for he says his purpose was to “to build up and not to tear down.”
5 For I consider that I have not in a single thing proved inferior to YOUR superfine apostles.
6 But even if I am unskilled in speech, I certainly am not in knowledge; but in every way we manifested [it] to YOU in all things. (2Co 11:5, 6 NWT)
11 I have become unreasonable. YOU compelled me to, for I ought to have been recommended by YOU. For I did not prove to be inferior to [YOUR] superfine apostles in a single thing, even if I am nothing. (2Co 12:11 NWT)
10 That is why I write these things while absent, that, when I am present, I may not act with severity according to the authority that the Lord gave me, to build up and not to tear down.
11 Finally, brothers, continue to rejoice, to be readjusted, to be comforted, to think in agreement, to live peaceably; and the God of love and of peace will be with YOU.
(2Co 13:10-11 NWT)
