Some of the teachings in the Book of the Law differed substantially from those held by other Mormon sects. For instance, in his "Note on the Sacrifice of Christ" and "The True God," Strang rejected both the traditional Christian doctrine of the virgin birth of Jesus and the Mormon doctrine of plurality of gods. He insisted that there was but one eternal God, the Father, and that progression to godhood, a doctrine taught by Joseph Smith in the King Follett sermon, was impossible. God had always been God, said Strang, and he was one person (not three, as in the traditional Christian Trinity).
