To return to your question HS.
Please understand that the Bible was never intended as a guide for converts, it was written for those who already were in the faith. It is not a full-scale theological exposition or a comprehensive catechesis. There are parts that are clearly very difficult to understand and easy to misinterpret. This was even true in the temporal immediacy of the 1st century. As Peter writes: Bear in mind that our Lord's patience means salvation, just as our dear brother Paul also wrote you with the wisdom that God gave him. He writes the same way in all his letters, speaking in them of these matters. His letters contain some things that are hard to understand, which ignorant and unstable people distort, as they do the other Scriptures, to their own destruction.
If we use textual criticism in evaluating Scripture we are able to conclude that we have a text with an accuracy that is more certain than that of any other ancient work. The Bible contains many fulfilled prophecies and is very accurate with respect to historical details as well. However, even if it did contain some historical inaccuracies, the message of scripture isn't detracted from. It isn't a history textbook but a spiritual guide.
Besides all this, I believe in Jesus Christ. Jesus Christ founded the Church, and the gates of hell would not prevail against it. What would be bound on earth would be bound in heaven by that mystical body. Christ entrusted the Church with authority and protected it, beginning with the 12 apostles. He enfused it with the Holy Spirit. The Church, using this authority, decided which books constituted Scripture and which did not (albeit after a considerable period of time and much disagreement) That Christianity had lasted so long under frequently very difficult circumstances without a universally accepted canon is evidence that the book is not the sole foundation of the faith.
However, regardless of any arguments I can put forward, I trust the Bible on faith.
Sincerely,
Burn
