The 42nd Annual Brigham Young University Sidney B. Sperry Symposium The Psalmist asks, “Who shall ascend into the hill of the Lord?” This year’s Sperry Symposium discusses ascending into the Lord’s moun- tain within the context of theophany, ancient temple worship, sacred space, sacrifice, offerings, and hymns and songs in the text of the Old Testament and the Book of Mormon. The scriptures contain a rich treasury of information of how ancient Israelites and the people in the Book of Mormon worshipped God and expressed themselves through ritual and devotions as found in the Psalms. These explorations of ancient temple worship help us to better understand and appreciate latter-day temple and worship traditions.
