According to The Church of Jesus Christ of Later Day Saint (The Mormons) - the phrase ''Sons of Perdition'' is related to those Persons who will not achieve The Afterlife or ''know God''. These Souls are either pre-determined to be ''Satanic Servants'' (in Spirit an perhaps unknowingly), and those who are not baptized into The Mormon Faith. As such, One will go into a Realm of Darkness, devoid of Light (God) and be forever tortured in a ''Lake of Fire''. Mormonism applied the term ''Perdition'' as both a physical (albeit supernatural) location and in context to Satan (as a proper name).
