"The Prophet Joseph Smith confirmed the Savior’s central role in our doctrine in one definitive sentence: “The fundamental principles of our religion are the testimony of the Apostles and Prophets, concerning Jesus Christ, that He died, was buried, and rose again the third day, and ascended into heaven; and all other things which pertain to our religion are only appendages to it.”
