Catena Aurea · Matthäusevangelium 26

He did not out of any fear forsake Christ, but through lust of money cast Him off; for in comparison of the love of money all our affections are feeble; the soul athirst for gain fears not to die for a very little; there is no trace of righteousness in that heart in which covetousness has once taken up its abode. The traitor Judas, intoxicated with this bane, in his thirst for lucre was so foolishly hardened, as to sell his Lord and Master.
