There are many Bible, but one faith - in Jesus Christ.
As the scriptures say: “There is one Lord [Jesus Christ], one faith [in Jesus Christ] ... one God and Father of all.”
That is what it comes down to. There are many Bibles, but as long as one puts their faith in Jesus, it really doesn’t matter what Bible [Protestant, catholic, Greek Orthodox, etcetera) you adhere to.
Oops, meant to say “many Bibles.”
Sure it matters for there are as many false Bibles and additions to these that are out there.
Examples:
Jehovah witnesses Bible and the additions to the Mormon Bible.
So you are wrong...it does matter what Bible one uses for the truth.
