"There are two Comforters spoken of. One is the Holy Ghost, the same as given on the day of Pentecost, and that all Saints receive after faith, repentance, and baptism." (Joseph Smith, HC 3:25)

"Baptism is a sign to God, to angels, and to heaven that we do the will of God, and there is no other way beneath the heavens whereby God hath ordained for man to come to Him to be saved, and enter into the kingdom of God, except faith in Jesus Christ, repentance, and baptism for the remission of sins, and any other course is in vain; then you have the promise of the gift of the Holy Ghost." (Joseph Smith, HC 4:32)
