Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 23
Woe unto you, Scribes and Pharisees, hypocrites! for ye compass sea and land to make one proselyte, and when he is made, you make him two fold more the child of hell than yourselves.
And that not of compassion from desire to save him whom they taught, but either from covetousness, that the greater number of worshippers might increase the number of offerings made in sacrifice, or out of vain glory. For he who sinks himself in a slough of sins, how should he be desirous to rescue another out of them? Will a man be more merciful to another than to himself? By a man’s actions therefore it may be known whether he seeks another’s conversion for God’s sake, or out of vain glory.
