“There Shall Be No Disputations among You” concerning the Ordinance of Baptism
3 Nephi 11:18–28
18 And it came to pass that he spake unto Nephi (for Nephi was among the multitude) and he commanded him that he should come forth.
19 And Nephi arose and went forth, and bowed himself before the Lord and did kiss his feet.
20 And the Lord commanded him that he should arise. And he arose and stood before him.
21 And the Lord said unto him: I give unto you power that ye shall baptize this people when I am again ascended into heaven.
22 And again the Lord called others, and said unto them likewise; and he gave unto them power to baptize. And he said unto them: On this wise shall ye baptize; and there shall be no disputations among you.
23 Verily I say unto you, that whoso repenteth of his sins through your words, and desireth to be baptized in my name, on this wise shall ye baptize them—Behold, ye shall go down and stand in the water, and in my name shall ye baptize them.
24 And now behold, these are the words which ye shall say, calling them by name, saying:
25 Having authority given me of Jesus Christ, I baptize you in the name of the Father, and of the Son, and of the Holy Ghost. Amen.
26 And then shall ye immerse them in the water, and come forth again out of the water.
27 And after this manner shall ye baptize in my name; for behold, verily I say unto you, that the Father, and the Son, and the Holy Ghost are one; and I am in the Father, and the Father in me, and the Father and I are one.
28 And according as I have commanded you thus shall ye baptize. And there shall be no disputations among you, as there have hitherto been; neither shall there be disputations among you concerning the points of my doctrine, as there have hitherto been.
President Joseph Fielding Smith said:
“There is nothing strange in the fact that when the Lord came to the Nephites, Nephi was baptized and so was everybody else although they had been baptized before. The Church among the Nephites before the coming of Christ was not in its fulness and was under the law of Moses. The Savior restored the fulness and gave to them all the ordinances and blessings of the gospel. Therefore, it actually became a new organization, and through baptism they came into it. We have a similar condition in this dispensation. The Prophet Joseph Smith and Oliver Cowdery were baptized by command of the Angel John the Baptist. Several others were baptized before the organization of the Church. However, on the day the Church was organized, all who had been previously baptized were baptized again, not for the remission of sins, but for entrance into the Church. In each case the reason was the same.”
