According to Margaret Barker's groundbreaking theory, temple mysticism
underpins much of the Bible. Rooted in the cult of the first temple in
ancient Judaism, it helps us to understand the origins of Christianity.
Temple mysticism was received and taught as oral tradition, and many
texts were changed or suppressed or kept from public access. Barker
first examines biblical texts: Isaiah, the prophet whom Jesus quoted
more than any other in Scripture, and John. Then she proposes a more
detailed picture, drawing on a wide variety of non-biblical texts. The
resulting book presents some remarkable results.
