If anyone, man woman or child, minister or teacher or politician or doctor, told me those lies,Flipping this question around:
If "Bob" told me that an angel appeared to him and told Him the Calvinistic views of the Gospel was true, I would acknowledge his view and continuing to respect him as a person, even while disagreeing with his beliefs and not believing his claimed experience.
If a person is seeking truth -- really seeking it -- they should first and foremost consult the Spirit of God. Not being a person going solely off another mortal person's claims.
it would not be possible to give them any respect, period, except maybe as God orchestrated for His Own Purpose at the time if needed. (as God's Judgment is Perfect, and is not late)
