Boasting over your tolerance of sin is inappropriate.
-I Corinthians 5:6a, TPT
Some churches welcome adulterous spouses. They have no shame about this behavior.
In fact, they celebrate how welcoming they are to these folks. It truly is head-scratching to think they see this sort of behavior as a faithful witness to how God wants them to treat adulterous individuals.
The “Christian” cheater finds a church that will welcome them with open arms. They fear no pressure to stop their sin in such environments. It is a “cheap grace” sort of church.
I wish I could say this was uncommon. However, I suspect this is more the rule than the exception.
