“Guard me around about with the loving and watchful care of Thy holy angels: and before their most sure defence may the enemies of all good, flee in confusion. For the sake of this dread mystery and by the ministering hand of the holy angel of the sacrifice, do Thou, O Lord, preserve me and all Thy servants from that obstinacy of spirit wherein lies pride and vain-glory, envy and blasphemy, uncleanness and wrong-doing, doubt and mistrust. Let them be confounded that persecute us. Let them perish that are bent upon our ruin.”
Devotions in Preparation for Mass and Communion, prayer for Sunday, in The New Roman Missal (Fr. Lasance), 1956.
