PHIL [Johnson]: There is, as you say, a concerted public relations effort under way right now to get evangelicals to accept Mormons as mainstream Christianity.
JOHN [MacArthur]: Right.
PHIL [Johnson]: And I encountered some of that literature recently. They actually quote from your books.
JOHN [MacArthur]: Well, I have met with the leaders of that Movement. There are a couple of guys, one of them is Robert Millet(?) who is the main teacher of Mormon theology...
PHIL [Johnson]: Teaches at Brigham Young, right?
JOHN [MacArthur]: Yeah...yeah, he’s the head of that department. But you have to understand, they don’t have any Bible interpreters. They don’t have any interpreters of Mormonism. They can’t interpret any of it. The presiding president apostle is, he has the final say on what is true. So all they can do is affirm these things. And they came to meet with me, invited me to Brigham Young, invited me...they wanted me to come into the city, they wanted me to talk to the faculty, talk to students. I tried to be as gracious as I could. I said, “You’ve got a different God, a different Christ, a different gospel, different source material and you’ve got a false religion. What am I going to gain by going there and having you pat me on the back like I’m some kind of co-belligerent here.”
So I have not gone and I’ve continued to correspond with these people. But to me this is a deeply insidious issue. Now what do you do to evangelize these people? First you realize there are two things you’ve got to say to a Mormon, one is this, “The Bible is the Word of God and the Bible alone is the Word of God.” Joseph Smith is a false prophet.
