Mormonism, like Roman Catholicism, is essentially a sacerdotal system — although that word most likely would not appear in any official doctrinal statement. It is clearly put forth in the Book of Mormon that without baptism, a person cannot be saved, because baptism is the prerequisite for receiving the Spirit of God. Right on the heels of condemning the Roman Catholic practice of infant baptism, the Book of Mormon falls into the same trap of investing baptism with the actual power of Spiritual regeneration.
(II Nephi 9:23-24) “And he commandeth all men that they must repent, and be baptized in his name, having perfect faith in the Holy One of Israel, or they cannot be saved in the kingdom of God. And if they will not repent and believe in his name, and be baptized in his name, and endure to the end, they must be damned; for the Lord God, the Holy One of Israel, has spoken it.”
(II Nephi 31:17) “For the gate by which ye should enter is repentance and baptism by water; and then cometh a remission of your sins by fire and by the Holy Ghost.”
(III Nephi 12:2) “Yea, blessed are they who shall believe in your words, and come down into the depths of humility and be baptized, for they shall be visited with fire and with the Holy Ghost, and shall receive a remission of their sins.”
(Moroni 6:1-4) “And now I speak concerning baptism. Behold, elders, priests, and teachers were baptized; and they were not baptized save they brought forth fruit meet that they were worthy of it. Neither did they receive any unto baptism save they came forth with a broken heart and a contrite spirit, and witnessed unto the church that they truly repented of all their sins. And none were received unto baptism save they took upon them the name of Christ, having a determination to serve him to the end. And after they had been received unto baptism, and were wrought upon and cleansed by the power of the Holy Ghost, they were numbered among the people of the church of Christ.”
(Moroni 8:11-14, emphasis added) “And their little children need no repentance, neither baptism. Behold, baptism is unto repentance to the fulfilling the commandments unto the remission of sins. But little children are alive in Christ, even from the foundation of the world; if not so, God is a partial God, and also a changeable God, and a respecter to persons; for how many little children have died without baptism! Wherefore, if little children could not be saved without baptism, these must have gone to an endless hell. Behold I say unto you, that he that supposeth that little children need baptism is in the gall of bitterness and in the bonds of iniquity; for he hath neither faith, hope, nor charity; wherefore, should he be cut off while in the thought, he must go down to hell.”
