For a decade now, we have had Mormonism adherents using nearly the same failed arguments as the poster to whom you addressed your excellent post. It is the Mormonism way to try and paint the Bible as unreliable in order to make a crack into which the fantasy novel from Joseph Smith may be injected In the case of the current naysayer the effort appears to be aimed at spitting on Christian believers. That is a sad soul which feels the need to do such in an effort to stroke their own ego. If no other source were used than the letters exchanged between the earliest Church Fathers dating to just 100 years after the Resurrection, the vast majority of the materials in the New Testament can be verified to a high degree. But the poster wants to have some phantasm upon which to build their disbelief, so the body of evidence must be reject out of hand.
Yes I would wholeheartedly agree with you.
Together in Christ we will always win, and they will always lose in the end.
If I question the provenance of the bible, calmly imagine what I think of the pretended sources of the Book of Mormon.
