Rebuke/false teachings

‘Whoever resents reproof walks in the sinner’s footsteps; whoever fears the Lord is repentant of heart’ [Sirach 21:6]. This does not mean that you should allow yourself to be intimidated by false teachings from those who claim to have seen the light by breaking out from the body of Christ {‘since as Christ is the head of the Church and saves the whole body…’ Eph.5:23}, (the Church of the living God, the pillar and support of truth 1 Tim.3:15), [“for nobody can lay down any other foundation than the one which is there already, namely Jesus Christ” 1 Cor.3:11].
