Gregory the Great — as excerpted in the Catena Aurea on Luke 7:36-50

“(in Hom. 33. in Evang.) For her eyes which once coveted after earthly things, she was now wearing out with penitential weeping. She once displayed her hair for the setting off of her face, she now wiped her tears with her hair. As it follows, And she wiped them with the hairs of her head. She once uttered proud things with her mouth, but kissing the feet of the Lord, she impressed her lips on the footsteps of her Redeemer. She once used ointment for the perfume of her body; what she had unworthily applied to herself, she now laudably offered to God. As it follows, And she anointed with ointment. As many enjoyments as she had in herself, so many offerings did she devise out of herself. She converts the number of her faults into the same number of virtues, that as much of her might wholly serve God in her penitence, as had despised God in her sin.”
