Our attitude toward abortion . . . is fixed by our knowledge that according to an eternal plan all of the spirit children of God must come to this earth for a glorious purpose, and that individual identity began long before conception and will continue for all the eternities to come. We rely on the prophets of God who have told us that while there may be 'rare' exceptions, 'the practice of elective abortion is fundamentally contrary to the Lord's injunction, 'Thou shalt not . . . kill, nor do anything like unto it'
