Eleven years later, the sentence was included in the Catechism of the Council of Trent of 1566. The catechism says that to the first part of the Hail Mary, by which “we render to God the highest praise and return Him most gracious thanks, because He has bestowed all His heavenly gifts on the most holy Virgin . . . the Church of God has wisely added prayers and an invocation addressed to the most holy Mother of God . . . we should earnestly implore her help and assistance; for that she possesses exalted merits with God, and that she is most desirous to assist us by her prayers, no one can doubt without impiety and wickedness. ” Soon after, in 1568 Pope Pius V included the full form as now known in his revision of the Roman Breviary.
