Divorce and remarriage

[good samaritan]

We don’t have a precedent to command a converted saint to leave a second marriage that they entered while in sin. We do have precedent of excommunication of saints that are dead set on entering unlawful unions such as incest ( and homosexuality would fit the bill as well).

Interesting situation:
A man I know just was in a revival where his current wife and his ex wife where present, and there was contention. These things should not be in the church of God and they give occasion to the adversary and bring reproach.
