I’ve had older family members who belonged to very strict churches that practiced shunning of unrepentant sinners. At one time, entire communities did so. It seems rather too severe to most in the modern era, and perhaps it errs too far on the side of caution, condemning souls to Hell who might otherwise be saved. But, we as Christians on the whole now err too far on the side of incaution, otherwise these seemingly daily posts of horrendous abuse and moral failure would not be such a topic of heated discussion.
This article is a perfect example of how the leftist media will hold this against all of us. And we fall for it each time, the aim to cause divisions, the spreading of hatred against Lutherans/Catholics/Pentecostals/Methodists/Jews/Orthodox etc.
