Remigius of Auxerre
Catena Aurea · Matthäusevangelium 7
Or what man is there of you, whom if his son ask bread, will he give him a stone? Or if he ask a fish, will he give him a serpent? If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him?
By the fish we may understand the word concerning Christ, by the serpent the Devil himself. Or by the loaf may be understood spiritual doctrine; by the stone ignorance; by the fish the water of Holy Baptism; by the serpent the wiles of the Devil, or unbelief.
