"Hail Mary, Full of Grace" is outside the Bible?

Also, what was the faith when the New Testament didn't exist yet? It was passed down faithfully via oral tradition.

So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter" (2 Thess. 2:15)

Actually, yes, I believe it is. Can you quote the Bible verse it comes from? Because I couldn't find it in several versions I searched through--here's what I found that matched it the closest though:
Luke 1:28:
28The angel went to her and said, "Greetings, you who are highly favored! The Lord is with you." (KJV)
28And coming in, he said to her, "Greetings, favored one! The Lord is with you." (NASB)
28The angel went to her and said, "Greetings, you who are highly favored! The Lord is with you." (NIV)
28 Gabriel appeared to her and said, “Greetings, favored woman! The Lord is with you![a]” (NLT)
28 The angel went to her and said, "Greetings, you who are highly favored! The Lord is with you." (TNIV)

Please read your Bible.

Jesus laid out what the Old Testament was before the resurrection. Peter recognized Paul's writings as inspired. Paul recognized Peter's writings as inspired. All the books of the New Testament were written before the last Apostle died.

IOW, the Scriptures were provided to us before the end of the Apostolic Era so that we would not fall into the same error as the Jews who had so grossly manipulated the law by their "tradition".
