Further study of the Book of Mormon's Visionary Men yields new insights into their worship and ideas, and also into other ancient scripture. John 1 uses ritual props and staging to introduce Jesus as the Lord; Helaman 5 recounts an endowment of power; Ether 3 is a temple account; and Isaiah is an underground prophet, describing the dark apostasy of his day in code.
This book is a follow-up to Plain and Precious Things: The Temple Religion of the Book of Mormon's Visionary Men, which should be read first.
