Luke 7:39

(ubi sup.) But the Pharisee beholding these things despises them, and finds fault, not only with the woman who was a sinner, but with the Lord who received her, as it follows, Now when the Pharisee who had bidden him saw it, he spake within himself, saying, This man, if he were a prophet, would have known who and what manner of woman this is which toucheth him. We see the Pharisee really proud in himself, and hypocritically righteous, blaming the sick woman for her sickness, the physician for his aid. The woman surely if she had come to the feet of the Pharisee would have departed with the heel lifted up against her. For he would have thought that he was polluted by another's sin, not having sufficient of his own real righteousness to fill him. So also some gifted with the priests' office, if perchance they have done any just thing outwardly or slightly, forthwith despise those who are put under them, and look with disdain on sinners who are of the people. But when we behold sinners, we must first bewail ourselves for their calamity, since we perhaps have had and are certainly liable to a similar fall. But it is necessary that we should carefully distinguish, for we are bound to make distinction in vices, but to have compassion on nature. For if we must punish the sinner, we must cherish a brother. But when by penance he has himself punished his own deed, our brother is no more a sinner, for he punished in himself what Divine justice condemned. The Physician was between two sick persons, but the one preserved her faculties in the fever, the other lost his mental perception. For she wept at what she had done; but the Pharisee, elated with a false sense of righteousness, overrated the vigour of his own health.

(in Hom. 33. in Evang.) Now in a mystical sense the Pharisee, presuming upon his pretended righteousness, is the Jewish people; the woman who was a sinner, but who came and wept at our Lord's feet, represents the conversion of the Gentiles.
