It puzzles me that more people don't study about the Nicene Council and how and why the choosing - by man - of which books would make it into the ‘BIBLE” and which - among many that were used by Christ's followers for 300 years - would be burned.
Do you really want to ride that train ?
Joe Smith, the uneducated carnival huckster, who never knew the original languages, never had access to the manuscripts, and borrowed heavily from the KJV (based on the questionable TR and Byzantine texts) rewriting inconvenient passages to suite his heresy. You are going to hold that up against the many manuscripts predating Nicaea, and the theological fire-power attending what was probably the first ecumenical meeting of the Church. All you have is Joe Smith's unsubstantiated and debunked claims, and you want to compare that to God's promise to always keep a remnant?
What kind of drugs are you doing ?
If I had to guess I would say LDS...
