Luke 17:11–19

Verse 14. To the priests. Jesus sends them to the priests, to convince the latter of the reality of the cures which he wrought, and oblige them by that to acknowledge him for their Messias; 2ndly, that the lepers might enjoy the fruit of their cure, by returning to the society of their fellow men, after they had been declared clean, and satisfied all the demands of the law; for there were may ceremonies previous to be gone through. Calmet.—And lastly, to shew that in the new law, such as are defiled with the leprosy of sin, should apply to the priests. Hence, says Saint Augustine, let no one despise God’s ordinance, saying that it is sufficient to confess to God alone. Lib. de visit. infirm.

Verse 19. Thy faith hath made thee whole. Were not the others also made whole? They were cleansed indeed from their leprosy, but it no where appears that they were justified in their souls like this Samaritan, of whom it said, thy faith hath made thee whole; whereas it was said of the others, that they were made clean, that is of their leprosy in their body, though not justified in their soul: this the Samaritan alone seems to have obtained. Maldonatus.
