DC 132:Intro SECTION 132
President Joseph Smith died at Independence, Missouri, December 10, 1914. His oldest living son, Frederick Madison Smith, had been designated as his successor and was accepted by the church in this capacity. He was set apart as President of the Church and the High Priesthood at the Stone Church in Independence on May 5, 1915.
The Conference of 1915 had given consideration to the honorable release of Presiding Bishop E. L. Kelley, but referred any necessary action to the Presidency and Council of Twelve. President F. M. Smith reported the situation to a council of the Presidency, Council of Twelve, and Presiding Bishopric. By action of this council the text of the revelation was taken from the body of President F. M. Smith's report and presented to the General Conference, where it was endorsed and approved for inclusion in the Doctrine and Covenants.
The matter of selecting one to succeed Bishop E.L. Kelley in the office of Presiding Bishop has received by me careful and prayerful consideration.
