Chastity is not charity; but, insofar as it is a refusal to grasp and an indefectible adherence to Him who gives, it forms its necessary condition.

A chaste life is thus a given life. “You must give over your life as you would toss a flower,” Madeleine Danielou said to her “daughters” of the apostolic Community of St. Francis Xavier. For “the grass dries up and the flower wilts, but the Word of our God abides forever” (Is 40:7-8; 1 Pt 1:24). full text.
