Since the 16th century Catholic piety has assigned entire months to special devotions. Toward the end of the eighteenth century a zealous Jesuit priest, Father Lalomia, started among the students of the Roman college of his Society the practice of dedicating May to Our Lady. The devotion, which others had promoted in a small way, soon spread to other Jesuit Colleges and to the entire Latin church and since that time it has been a regular feature of Catholic life.
Thou who wast a virgin before thy delivery, pray for us. Hail Mary, etc. Thou who wast a virgin in thy delivery, pray for us. Hail Mary, etc. Thou who wast a virgin after thy delivery, pray for us. Hail Mary, etc.
My Mother, deliver me from mortal sin. Hail Mary (three times).
Mother of love, of sorrow and of mercy, pray for us.
Remember, O Virgin Mother of God, when thou shalt stand before the face of the Lord, that thou speak favorable things in our behalf and that He may turn away His indignation from us. Roman Missal
Thou art my Mother, O Virgin Mary: keep me safe lest I ever offend thy dear Son, and obtain for me the grace to please Him always and in all things.
FOR THE HELP OF THE BLESSED VIRGIN MARY
May we be assisted, we beseech Thee, 0 Lord, by the worshipful intercession of Thy glorious Mother, the ever-Virgin Mary; that we, who have been enriched by her perpetual blessings, may be delivered from all dangers, and through her loving kindness made to be of one heart and mind: who livest and reignest world without end. Amen.
