Who said the Hail Mary to Mary?

Answer 1

Actually, the words "Hail Mary" were not found in the New Testament, and the prayer to Mary known today as part of the Rosary is a much later additions to the Christian (especially Roman Catholic) canon of prayers. The original greeting to Mary did not use her name: it was "Hail, full of grace, the Lord is with thee." It was spoken by the Angel Gabriel, as quoted in the Gospel of Luke. Years later, when the role of Mary, as the Mother of Jesus and the Blessed Virgin, was expanded, prayers specifically asking for her intercession and help were developed-- but church scholars do not believe the "Hail Mary" prayer was used before the Middle Ages; and in its original Latin form, the prayer we know today was called the "Ave Maria."
