Beck is a Mormon - Christian Syncretist

Finally, we have to have a grid for thinking through degrees of error, damnable beliefs, essential beliefs, etc. I’ve been helped here by Michael Wittmer’s excellent book, Don’t Stop Believing: Why Living Like Jesus Is Not Enough. He classifies Christian beliefs into  three categories:

1. What you must believe,
2. What you must not reject, and
3. What you should believe.

I asked him to explain the three categories:

In the book of Acts, the bare minimum that a person must know and believe to be saved was that he was a sinner and that Jesus saved him from his sin. As Paul told the Philippian jailer, “Believe in the Lord Jesus and you will be saved” (Acts 16:29-31; cf. 10:43). This is enough to counter the postmodern innovator argument that we can be saved without knowing and believing in Jesus.
But any thinking convert will inquire further about this Jesus. While he may not know much more at the point of conversion than Jesus is the Lord who has saved him, he will quickly learn about Jesus’ life, death, resurrection, deity and humanity, and relation to the other two members of the Trinity. Anyone who rejects these core doctrines should fear for their soul.
According to the Athanasian Creed, whoever does not believe in the Trinity and the two natures of Jesus is damned. However, since it seems possible for a child to come to faith without knowing much about the Trinity or the hypostatic union (this is likely not the place where most parents begin), I take the Creed’s warning in a more benign way—that we do not need to know and believe in the Trinity and two natures of Christ to be saved, but that anyone who knowingly rejects them cannot be saved.
The final category is important doctrines which genuine Christians may unfortunately misconstrue. I think that every Christian should believe that Scripture is God’s Word, know its story of creation, fall, redemption, and consummation, and know something about the nature of God, what it means to be human, and what Jesus is doing through his church. However, many people have been genuine Christians without knowing or believing these things (though their ignorance or disbelief in these facts significantly diminished their Christian faith).
Thus, I believe that every doctrine in this diagram is crucially important for sound Christian faith. And some are so important that we cannot even be saved without them.

If Glenn Beck is a Mormon, he knowingly denies beliefs that one must believe in order to be saved. Let us pray that he leaves this religion in order to embrace the eternal Son of God, Jesus Christ, and his atoning cross-work so that he has fellowship by grace alone through faith alone with the Triune God.
