Joseph Smith was the patron of the Church of Jesus Christ of Latter-day Saints. After he was assassinated, his work was resumed by Brigham Young. The First Revelation relates to a concept that Joseph Smith said he received in the spring of 1820, in a woody area in Manchester, New York, which his supporters call the Sacred Grove. Smith explained it as an individual theophany in which he got guidance from God.
