One needs to distinguish a sinner from a penitent. If you have taken upon yourself the role to rebuke the sinner, guard yourself well, that you do not rebuke the penitent also. How dear the repentant sinner is to God; call to mind the Parable of the Prodigal Son. Therefore, let it be very dear for you, he who has become dear to God.
Saint Nikolai Velimirovic
