I would add that most of the prayers used when saying the Rosary come straight from the Bible.
The two prayers used throughout are the “Our Father,” which Jesus himself instructed us to say, and the “Hail Mary,” more than half of which is taken directly from the words of the Archangel when he appeared to Mary: “Hail Mary, full of grace, the Lord is with thee. Blessed art thou among women, and blessed is the fruit of thy womb, Jesus.” The prayer adds the words Jesus to the biblical text, but I don’t think that is anything more than filling in the obvious.
Each decade ends with “Glory be to the Father, and to the Son, and to the Holy Spirit, as it was in the beginning, is now, and shall be forevermore.” I think that’s unexceptionally in accordance with the Bible, too.
And the Rosary starts with the Apostles’ Creed, which I think most orthodox Protestants accept.
Also, you might take a look at the Wedding Feast of Cana. Jesus was not yet ready for his Public Life, but his mother came to him and asked him to change to water into wine. He agreed to do so, although the time was not yet. And he told the servants: “Do whatever she tells you.”
“I would add that most of the prayers used when saying the Rosary come straight from the Bible.”
I don’t think anyone has a problem with the parts that are taken from the Bible. The other parts are what cause the controversy.
Your religion probably actually teaches this...Why else would it be in your mind and your mouth???
