Where is this in the Bible?
Nobody believed such things until catholicism made it up.
Beware of "other Gospels" that elevate a dead girl into things she isn't.
You exaggerate HOW blessed Mary was. But solid Bible-based Christians don't do this exaggeration.
Where in the Bible does it say that everything Christ did and taught, or everything we are to believe is restricted to the Bible. (read John 21:25, that says that not everything Christ did and taught is in the Bible. Yet Matt. 28:20 has Christ commanding the Apostles to teach all that He taught them. In fact, the New Testament wasn't decided until the late 4th century, when the Catholic Church went through over 300+ documents, praying to the Holy Spirit for guidance, and coming up with the 27 books we all agree on are the New Testament.
Christ didn't write a book to spread His truths, He founded a (one) Church, the Catholic Church, to do so. It would have been useless to found a Church based on a book, since the vast, vast majority of humanity was illiterate for the first 18+ centuries of Christianity. That would have effectively eliminated 95+% of humanity from learning Christ's message.
You might also review 2 Peter 1:20-21, where St. Peter warns against personal interpretation of Scripture.
Original KJV had the 73 books of the
Cannon approved by the council of Rome and promulgated by papal authority in 381!
The authority of Christ in His apostolic church gave is the authentic scriptures, and the authentic interpretation!
For hundreds of years the authority of Christ acted and operated in His apostolic church without scripture, and the apostolic church wrote the New Testament.
The apostolic church is not dependent upon scripture:
The apostolic church does not need scripture to know truth, Christ taught “all truth” Jude 1:3 to His apostolic church in person for three years, the church does not need scripture to exercise her authority from Christ to teach and sanctify all nations unto eternal salvation, and to govern the church.
“Christ founded a church to teach and sanctify all men unto
Eternal salvation”: Matt 28:28 Lk 1:4 acts 1:8, 2:42, 8:31 Jn 16:13, 20:21-23 Matt 18:17 1 Tim 3:16
1 Jn 1:4
