that he would not yield, and thus Pratt was excommunicated on August 20, 1842. Pratt reconciled with Smith a few months after their falling out and requested re-baptism. Pratt was reinstated in the Quorum of the Twelve Apostles on January 20, 1843. Sources claim that Pratt returned to fellowship in the LDS Church because he was able to reconcile Smith's human weakness with his divine revelations, and others point to Smith's explanation that he was only trying to test Sarah's obedience, though Joseph's conclusion was that Sarah had failed the test of obedience by not accepting his proposal. Conflict with Brigham Young Pratt's brief period of disassociation with the church had long-term consequences. When dealing with seniority in the council after the death of Joseph Smith, Brigham Young ruled that if a council member had been disciplined and removed from the council, his seniority was based on the date of readmission. By this ruling, both apostle Orson Hyde and Pratt were moved down in seniority in June 1875. This ensured that neither would become president of the LDS Church.

Young expressed an appreciation for Pratt's ability to preach but added regrettably that Pratt preached "false doctrine" more often than not.

Missionary service After settling in the Salt Lake Valley with the Mormon pioneers, Pratt was called to return to Europe as a mission administrator between 1848 and 1851, during which time he also served as editor of the Millennial Star. In 1850, as mission president of the British Mission, Pratt told his missionaries his strategy for spreading the gospel in an article titled, "How to Warn the
