How did Joseph's Masonic membership affect the development of the Mormon Church? The most significant area appears to be in the development of the Mormon temple ceremonies. As noted above, Joseph became a Mason on March 15, 1842 and "rose to the sublime degree" the following day. Less than two months later, on May 4, 1842, Joseph introduced the temple endowment ceremony (History of the Church, Vol. 5, pp. 1-2).
