Isaac Sheen writes that, in the Endowment, there is a God above God the Father.
Isaac Sheen, "The Man of Sin," Aaronic Herald 1, no. 1 (February 1, 1849): 1
In the pretended endowments in the temple at Nauvoo, (according to the testimony of some who went through those performances,) there was a presence made to represent the Garden of Eden, and Adam and Eve therein, whilst Brigham Young blasphemously personified the God of Gods, answering to his name. The old sects don’t believe in the existence of any being higher than the Father of Jesus Christ, and therefore cannot counterfeit that which they have no idea or belief in. But it is a doctrine of the Church of Jesus Christ of Latter Day Saints that there is such a being, and Brigham Young has had the daring audacity to personify such a being.
