I don’t call child rapists and molesters my Christian brothers.
Are you insinuating that all Catholics are child rapists and molesters and not your brothers in Christ?
Ditto - regardless of what Catholic/Orthodox church or Protestant/Evangelical denomination that they try and hide within.
...But actually, I wrote to you not to associate with any so-called brother if he is an immoral person, or covetous, or an idolater, or a reviler, or a drunkard, or a swindler--not even to eat with such a one.
