No of course not. The Hail Mary is actually scriptural. “Hail Mary, full of grace, the Lord is with Thee, Blessed art Thou amongst women and Blessed is the Fruit of Thy Womb Jesus” is from Luke if I’m not mistaken.
“Holy Mary Mother of God”- If Jesus is 100% God 100% Man, Mary cannot just be the Mother of His Humanity, but also His Divinity.
“Pray for Us Sinners, now and at the hour of our death”- Think about it like this. Would you ask a friend to pray for you? Yes, probably. So you would definitely ask Jesus’ own Mother to pray for you right?
God Bless!!!
