114 And you, white legions of children who are so loved and dear to Jesus, when you receive in Holy Communion the Bread of Life, raise up your simple and innocent prayers and unite them with those of the Universal Church. The heart of Jesus, Who loves you, does not resist your suppliant innocence. Pray every one, pray uninterruptedly: "Pray without ceasing" ( Thessalonians , v. 10).
