Do you ever just get sick of lying to yourself? There are so many questions we have that are never answered because of the greater good or pragmatic traditional positions, not to mention the much work being done 24/7 building the Kingdom of the Lord, socializing and reforming all society! At what point is the body of Christ allowed to discuss our divisive matters openly? When do men just get together to plod through the scriptures on a subject that comes up continually? I don't care how long something has been happening or who says we should keep doing it.
Paul laid down specifics on sound doctrine and church discipline (withdrawing) with the intention to establish truth and put down heresy and false gospels, not to just to cast the sinners out or the ignorant heretic. Heresies are a work of the flesh like anything else (Gal 5:20). Heresies must be for the word of God to be established as the authority. You're approved by sticking to the Book, and those things left to the body of Christ, not by hanging around in the OT, the prophets, the gospels, and early Acts.
1 Cor 11:18-19 For first of all, when ye come together in the church, I hear that there be divisions among you; and I partly believe it.
For there must be also heresies among you, that they which are approved may be made manifest among you.
If there is division, there is heresy. The body is meant to be unified. It's a work, and it won't happen overnight. Dealing with false doctrine is how a church comes to a unified position, established in the faith. The gospel being confirmed, and defended. When Paul talks of dealing with a man that is a heretic, it is an admonition (gentle reproof, counseling against a fault, instruction in duties, direction, to caution). It is one thing if a man is openly subverting, seeking preeminence, drawing sheep away, but for a brother in Christ to bring valid arguments to some long-standing traditions, he is not attempting to teach heresy, he is attempting to understand the present conditions of things as they relate to the scriptures, more specifically for us living today, parts of the NT to keep himself from losing his marbles!
