There are too many churches and church leaders that warp scripture. My understanding is that if the church knows of members that are actively sinning without repentance they are to be dealt with (judged) up to being removed from that body. avoidance of judgment is for the unsaved. But please note that avoiding judgment doesn’t preclude speaking truth with love for those who are lost.
I have no way to know if she and her husband are saved. I think that if they were in an active relationship with the Lord Jesus Christ this would be unthinkable, but God knows the heart and it’s capacities; I don’t.
In any case, I doubt the value of posts that point out the obvious. I don’t necessarily disagree. Indeed, my first thoughts were that similar excuses were probably offered by guards in conversation over coffee at Auschwitz.
But they will never see these condemning posts. If we want to make a difference, and we belong to Him, we should be praying for them and grieving over the misery this is causing.
