The Book of Mormon has almost no explicit mention of justification, but it can be inferred from the text that a person’s justification is by faith in Christ and his own works — particularly through the rite of baptism, which will be explained in more detail in the next section.

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 8:25-26) “And the first fruits of repentance is baptism; and baptism cometh by faith unto the fulfilling the commandments; and the fulfilling the commandments bringeth remission of sins; And the remission of sins bringeth meekness, and lowliness of heart; and because of meekness and lowliness of heart cometh the visitation of the Holy Ghost, which Comforter filleth with hope and perfect love …”
