Augustine of Hippo — as excerpted in the Catena Aurea on Matthew 26:6-13

“(de Doctr. Christ. iii, 12.) But let not any suppose that the Lord’s feet were by this woman bathed in ointment after the manner which the luxurious and debauched use. In all things of this nature, it is not the thing itself, but the mind of him who uses it, that is in fault. Whoso uses things after such sort as to pass the bounds observed by good men with whom he lives, either has some meaning1 in what he does, or is vicious. What then is vice in others, in a divine or prophetic person is a sign of some great thing. The good odour is the good report which one has gained by the works of a good life, and in following Christ’s footsteps sheds a most precious odour on His feet.”
