As an Anglican convert to Catholicism while studying at Harvard (not what my Harvard professors would have wished), I was a bit standoffish of the Rosary at first. But I have come to the point of saying it daily, in the evening.
Just about all the prayers in the Rosary are biblical. The Apostle’s Creed, which is a kind of summary of Bible teachings. The Lord’s Prayer, which Christ himself commanded us to use. And the Hail Mary, which Protestants may at first find disturbing. But the first half of the Hail Mary is straight from the Bible—the words of the Archangel to the Virgin Mary at the Annunciation. And the second half asks Mary to pray for us, “that we may be made worthy of the promises of Christ.” It is not an adoration of Mary, not idolatry, but a fervent request that the Mother of God will intercede for us with her Son, and will help to show us her Son.
Finally, each decade ends with a Glory be to the Father, and to the Son, and to the Holy Spirit. . . .” So, we pray to all three persons of the Trinity in the course of saying the rosary, as well as asking Mary’s intercession. Jesus Himself said to the servants at the wedding feast of Cana, “Do whatever she tells you.” Because Mary will never say or do anything that goes against His wishes.
As for the Mysteries of the Rosary, those two are basically biblical, and they are centered on the life of Jesus, or on Mary giving birth to Jesus, presenting or finding him in the Temple, and so on. It is because all that she does is directed toward God that the Bible says that “all generations” will call Mary blessed.
“Those two” should be “Those too.”
"His mother saith to the waiters: Whatsoever he shall say to you, do ye." -John 2:5.
Mary always points the way to her Son.
So, if we need to ask Mary to ask her Son to help us, (I guess He needs convincing?) do we first need to ask someone else to ask Mary to ask Jesus? You know, does she, like...need convincing too, like Jesus needs to be convinced to help us?
You know, like “Hail Elizabeth, please ask Mary to ask Jesus, to help us...”?
