John Chrysostom — as excerpted in the Catena Aurea on Luke 20:45-47

“Thrusting themselves also into the possessions of widows, they grind down their poverty, not content to eat as it may be afforded them, but greedily devouring; using prayer also to an evil end, they thus expose themselves to a heavier condemnation; as it follows, These shall receive the greater damnation.”
