Brigham Young teaches that every earth had its own redeemer and tempter.
Brigham Young, "Sin—the Atonement—Good and Evil—the Kingdom of God," Journal of Discourses, 26 vols. (Liverpool: Albert Carrington, 1872), 14:71-72
But the fact exists that the Father, the Divine Father, whom we serve, the God of the Universe, the God and Father of our Lord Jesus Christ, and the Father of our spirits, provided this sacrifice and sent his Son to die for us; and it is also a great fact that the Son came to do the will of the Father, and he has paid the debt, in fulfillment of the Scripture which says, "He was the Lamb slain from the foundation of the world." it is so on any other earth? On every earth. . . . Sin is upon every earth that was created. . . . Consequently every earth has its redeemer, and every earth has its tempter; and every earth, and the people thereof, in their turn and time, receive all that we receive, and pass through all the ordeals that we are passing through.
