You won't get an argument from me on the others you posted, but the one above surely adds to what was revealed.
The "holy Mary mother of God, pray for us sinners now and at the hour of our death, Amen" however is not in Scriptures. But that discussion is on another thread, so we digress a bit.
So what if the last part isn’t in Scripture? Is a praise band in Scripture, or an altar call? How about a mini-mall, or coffee bar? Pews, Sunday best, women ministers? Nope, nope and nope.
Not to be short with anybody, but the Bible doesn’t limit our ability to praise God, or seek the intercession of others.
The imitation of the Angelic Salutation, followed by the words of Elizabeth, and then followed by a petition are pretty darn Biblical. To argue otherwise is nit picking.
“however is not in Scriptures”
No it’s not because it’s of this world.
