Chapter 11 — Part I: The Creed — Article IX: The Holy Catholic Church; the Communion of Saints
Section 61. Communion Of Good Works — But there is also another communion in the Church which demands attention. Every pious and holy action done by one belongs to and becomes profitable to all through charity, which seeketh not her Own. This is proved by the testimony of St. Ambrose, who, explaining these words of the Psalmist, I am a partaker with all them that f ear thee, observes: As we say that a limb is partaker of the entire body, so are we partakers with all that fear God. Therefore has Christ taught us that form of prayer in which we say our, not my bread; and the other Petitions are equally general, not confined to ourselves alone, but directed also to the common interest and the salvation of all.
