Is it a sin (blasphemy against the Holy Spirit) to say that Satan visited Joseph Smith (leader of the mornons) instead of God? There was a girl at my church who I've seen was carrying "the book of mormon" . I explain to her that the mormons teaches a false religion and that Joe Smith claimed that he was visited by Jesus the Son and God the Father. I told her that it was not God who visited him but a demon. For the bible says in John 1:18 "No man hath seen God at any time, the only begotten Son, which is in the bosom of the Father, he hath declared him."
