Chapter 33 — Part IV: Prayer — On Prayer in General
Section 51. Enemies And Those Outside The Church — The Lord has also commanded us, to pray for those that persecute and calumniate us. The practice of praying for those who are not within the pale of the Church, is, as we know on the authority of St. Augustine, of Apostolic origin. We pray that the faith may be made known to infidels; that idolaters may be rescued from the error of their impiety; that the Jews, emerging from the darkness with which they are encompassed, may arrive at the light of truth; that heretics, returning to soundness of mind, may be instructed in the Catholic faith; and that schismatics may be united in the bond of true charity and may return to the communion of their holy mother, the Church, from which they have separated.
