“If anyone comes to you and does not bring this teaching, do not receive him into your house or give him any greeting, for whoever greets him takes part in his wicked works”– 2 John 10, 11.
At the heart of Christianity is love. Paul reminds us that of the three, faith, hope, and love, the greatest is love (1 Cor. 13:13). However, we should not confuse love with tolerance of falsehood. Love does not mean paying a blind eye to heresy that threatens to destroy the Church. Christians must never give approval or support to false teachers. Those who preach the false gospel, which is no gospel at all, are not misguided brothers but the enemies of the cross of Christ (Phil. 3:18). Of course, we should pray for them, love them while hating their falsehood, show them their error, and strongly challenge them to repent. But Christians should not offer them any encouragement or hospitality for it might be interpreted as a sign of approval. The false teachers might also take advantage of any hospitality shown to them to pounce on the unsuspecting and vulnerable people with their heresies. This for sure is tough love.
