Roman Catechism 33.19

Chapter 33 — Part IV: Prayer — On Prayer in General

Section 19. Prayer Increases Charity — Our charity is also augmented. In recognising God as the author of every blessing and of every good, we are led to cling to Him with the most devoted love. And as those who cherish a mutual affection become more ardently attached by frequent interviews and conversations, so the oftener the soul prays devoutly and implores the divine mercy, thus holding converse with God, the more exquisite is the sense of delight which she experiences in each prayer, and the more ardently is she inflamed to love and adore Him.
