Here is something to think about
3rd John 1:9-10 I wrote unto the church: but Diotrephes, who loveth to have the preeminence among them, receiveth us not. Wherefore, if I come, I will remember his deeds which he doeth, prating against us with malicious words: and not content therewith, neither doth he himself receive the brethren, and forbiddeth them that would, and casteth them out of the church.
Many people say we shouldn't name names when discussing proponents of false doctrine but should refute their doctrine only but I think it is wise and only right to warn people of certain men and expose them.This only of course if they will not be corrected privately by sound doctrine.
Look at John here, watch out for Diotrophes he says, he like to be first, he likes to be highest, he will not accept apostolic authority, he rejects the brethren.
Judge not? or judge righteous judgement.
