Doctrinal Treatises of St. Augustin: Chapter 7

Chapter 7.—The Creed and the Lord’s Prayer Demand the Exercise of Faith, Hope, and Love.

For you have the Creed and the Lord’s Prayer. What can be briefer to hear or to read? What easier to commit to memory? p. 239 When, as the result of sin, the human race was groaning under a heavy load of misery, and was in urgent need of the divine compassion, one of the prophets, anticipating the time of God’s grace, declared: “And it shall come to pass, that whosoever shall call on the name of the Lord shall be delivered.” 1096 Hence the Lord’s Prayer. But the apostle, when, for the purpose of commending this very grace, he had quoted this prophetic testimony, immediately added: “How then shall they call on Him in whom they have not believed?” 1097 Hence the Creed. In these two you have those three graces exemplified: faith believes, hope and love pray. But without faith the two last cannot exist, and therefore we may say that faith also prays. Whence it is written: “How shall they call on Him in whom they have not believed?”
