Note 12 — Chapter VI
Reading edition
"St. Thomas and many other grave doctors say that it is by reason of the war that the devil is accustomed to make against those that are in prayer, that the Church, directed by the Holy Ghost, ordains that we should begin all the canonical Hours with this verse, 'O God, make speed to save me: O Lord, make haste to help me.' Whereby we implore God's assistance in prayer against the snares and temptations of the enemy."—Quoted by Rodriguez, Christian Perfection.
