Augustine of Hippo
Catena Aurea · Lukasevangelium 5
And it came to pass, when he was in a certain city, behold a man full of leprosy: who seeing Jesus fell on his face, and besought him, saying, Lord, if thou wilt, thou canst make me clean. And he put forth his hand, and touched him, saying, I will: be thou clean. And immediately the leprosy departed from him. And he charged him to tell no man: but go, and shew thyself to the Priest, and offer for thy cleansing, according as Moses commanded, for a testimony unto them. But so much the more went there a fame abroad of him: and great multitudes came together to hear, and to be healed by him of their infirmities. And he withdrew himself into the wilderness, and prayed.
(de Qu. Ev. l. ii. qu. 3.) He seems here to approve of the sacrifice which had been commanded through Moses, though the Church does not require it. It may therefore be understood to have been commanded, because not as yet had commenced that most holy sacrifice which is His body. For it was not fitting that typical sacrifices should be taken away before that which was typified should be confirmed by the witness of the Apostles’ preaching, and the faith of believers.
