When I met with [Mormon apologist] Robert Millet I expressed my conviction as clearly as possible that the God of the Bible is a completely different God from the god of Mormonism, that the Christ of Scripture is a wholly different Christ from the christ of Mormonism, and the true gospel is a radically different gospel from the gospel of Mormonism.
I have maintained a cordial relationship with Dr. Millet for the sake of the truth, and am happy to provide him with as much of my material as he wishes to read. But my concern is for the truth; I’m not interested in artificial harmony between two contradictory faiths. For that reason I have consistently made clear in all my dialogue with Dr. Millet that there is no spiritual common ground between biblical Christianity and Mormonism.
I would never deliberately equivocate on the truth or do anything that might lend credence to Mormonism. I’m convinced (as are all who understand Scripture accurately) that Mormonism is a false religion, generated by Satan. It is a damnable heresy, and in the words of Paul, “a different gospel,” under God’s anathema. (Final notes on the Mainstreaming of Mormonism)
