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?
The sense therefore is; we need not fear that should we ask of God our Father bread, that is doctrine or love, He will give us a stone; that is, that He will suffer our heart to be contracted either by the frost of hatred or by hardness of soul; or that when we ask for faith, He will suffer us to die of the poison of unbelief. Thence it follows, If then ye being evil.
