And there are enemies of the Church, outside and even from within!
And it is CHRISTIAN CHARITY if you call out a brother of his errors!
If your brother sins against you, go and tell him his fault between you and him alone. If he listens to you, you have won over your brother. If he does not listen, take one or two others along with you, so that ‘every fact may be established on the testimony of two or three witnesses. (Matt 18:15)
