The Holy Ghost is believed to be subordinate to the Father and the Son and operates under their direction. The Holy Ghost, like all intelligent beings, is believed to be fundamentally eternal, uncreated, and self-existent.[80] Mormonism teaches that the influence of the Holy Ghost can be received before baptism, but the gift, or constant companionship, of the Holy Ghost, which comes by the laying-on of hands by a properly ordained Priesthood Holder with a line of authority traced back to Christ through Peter, is obtained only after baptism.[81] Joseph Smith, the founding prophet of Mormonism, taught "You might as well baptize a bag of sand as a man," he said, "if not done in view of the remission of sins and getting of the Holy Ghost. Baptism by water is but half a baptism, and is good for nothing without the other half-that is, the baptism of the Holy Ghost".[82]
