Master Mahan Master Mahan
From Wikipedia, the free encyclopedia
In the religious texts of the Latter Day Saint movement, Master Mahan is a title assumed first by Cain and later by his descendant Lamech. The title indicates that Cain and Lamech were each the "master" of a "great secret" whereby they covenanted with Satan to kill for personal gain.[1] The term is found in Joseph Smith, Jr.'s translation of the Bible, Genesis 5 (currently published by the Community of Christ), and as an excerpt in the Pearl of Great Price, Book of Moses 5, a religious text of The Church of Jesus Christ of Latter-day Saints (LDS Church).
Scholars approaching the issue from a secular perspective, who argue that Joseph Smith's translation of the Bible was influenced by his cultural environment including strong local anti-Masonry, generally suggest that the term is related to Master Mason, the highest degree of the Blue Lodge of freemasonry.[2] Another suggestion is that the term is related to Mahoun, a pejorative reference to Muhammad during the Middle Ages which eventually became associated with witchcraft by Joseph Smith's era.[3] Apologists, however, generally argue that references to Master Mahan were restored by Joseph Smith from missing parts of the Bible, and therefore the term has middle-Eastern roots. Consequently, the LDS Church's publications suggest that the term Mahan could mean either mind, destroyer, or great one,[4] and one prominent Mormon apologist speculates that the term is related to Arabic and Sanskrit words meaning "keeper of a great secret".[5
