I too struggle with which books of the Bible should or should not be there. The Catholic Church being the first Church had much to do with which books are in the Bible.
Yes, The Roman Catholic Church finanlized the Biblical canon at The Council of Trent in 1546.
As a Christian, one must conclude that the Holy Spirit's work in this matter was not "flawed".
Therefore, we must essentially, by faith, place our trust in the Roman Catholic Church's ability to set in stone,
thee definitive Biblical canon for the Christian Church.
But, ever since, 33,000+ protestant denominations have been detracting certain books from the Biblical canon because they don't fall in line with their particular theologies.
Christians should remain open to reading/studying the original Biblical canon, and refuse to be brainwashed into thinking it is/was flawed simply because the Roman Catholic Church finalized it.
Especially, since it is our belief that the Holy Spirit was at work during the finalization of the Biblical canon.
If He wasn't at work, then we are
still without a Biblical canon.
Bottom line- The books which belong in the Christian Bible have been established at the Council of Trent. So, are we going to rely upon and trust that The Church "got it right" with the Biblical canon, or are we going to detract from it as has been going on for centuries throughout the 33,000+ protestant denominations?
I'd much rather choose the former so I can settle the matter within my own soul, thus keeping myself from becoming "a wave of the sea driven and tossed by the wind" because of the doubts that would constantly arise. James 1:6.
