Starting this month, adult Latter-day Saints will shelve their study of past Mormon prophets and return to fundamentals of their faith as spelled out in a 30-year-old book called Gospel Principles .
Twice a month, Mormon men in their Sunday priesthood meetings and women in their Relief Society sessions will consider a different chapter in the book, originally published in 1978, which discusses everything from the nature of God and Christ's atoning sacrifice to the need for baptism and temple rituals.
Until now, the book largely has been used as a primer for new converts to the 13.5 million-member Church of Jesus Christ of Latter-day Saints.
But church officials believe it can enhance worship for longtime members as well.
"The more we reflect on the principles and doctrines, the greater our understanding becomes," Elder Kenneth Johnson of the Seventy, who oversaw the revision of the manual, said in the Ensign , the church's official magazine. "They never grow old, and our understanding of them is increased and enhanced. The truth is not just an intellectual truth, but more of an understanding as the Spirit is present."
