I’m looking at the intro to Hebrews from the NIV, its says:
“Although the author of Hebrews is unknown, this book was probably written in the late A.D. 60’s...”. It did not stop me from accepting it as part of the Word of God. It’s in there because the Lord WANTED it in there.
That is your belief. You don't know that for sure,m unless you can prove it! What we do know is that it's in the Bible because the Church erroneously believed it was apostolic in origin.
Of course, we can attribute everything to God, including natural disasters, famines, and injustice; who's is going to prove it otherwise. Claiming that it is is no proof. It's a speculation.
