Rotfl... excuse me, but there were always the influence of idolatry, Hellenism, foreign cultures, etc., and we don't consider those legitimate.Equivocating a Jewish sect living in Palestine 2,200 years ago with Joseph Smith is absurd. That has got to be the weakest dodge I have ever seen on CARM.
Do you accept that Paul was the man of lies lies talked about in the Qumran docs?
So, why don't you consider the JWs, Mormons, Moonies, RCC, SDAs, etc., legitimate when they use the same NT as you do? Why are you dodging this?
