In the mid-second century A.D., a devout Christian named Hermas wrote an account of some of his visions, in a book that has come to be known as The Pastor of Hermas because he described an angel who appeared to him in the form of a pastor or shepherd. His visions depicted the Church as a temple into which the righteous, represented by stones, were placed. Shown a beast with four colors on his head, he asked the meaning and was told that “the white part is the age that is to come, in which the elect of God will dwell, since those elected by God to eternal life will be spotless and pure.”
Another early Christian writer who compared white clothing to purity was Ambrose, Bishop of Milan (died A.D. 397). Commenting on the third chapter of Zechariah, in which the prophet describes the high priest Joshua (the Hebrew source of the name Jesus) wearing a filthy garment that the angels replace with a clean white garment, Ambrose wrote, “But Christ, beholding His Church, for whom He Himself, as you find in the book of the prophet Zechariah, had put on filthy garments, now clothed in white raiment, seeing, that is, a soul pure and washed in the laver of regeneration” (Concerning the Mysteries 7 [37]).
In his fourth catechitical lecture (22:8), St. Cyril of Jerusalem cited Ecclesiastes 9:8 (“Let thy garments be always white; and let thy head lack no ointment”) and added, “But now, having put off thy old garments, and put on those which are spiritually white, thou must be continually robed in white: of course we mean not this, that thou art always to wear white raiment; but thou must be clad in the garments that are truly white and shining and spiritual.” From this, it is clear that the concept of white garments is symbolic.
Contrasted with the clean, white garments of the righteous are those of the wicked. Isaiah wrote, “But we are all as an unclean thing, and all our righteousnesses are as filthy rags” (Isaiah 64:6). The Hebrew word rendered “rags” in this passage is beged, which means “garment, piece of clothing.” Zechariah wrote of his vision of the high priest Joshua, “Now Joshua was clothed with filthy garments, and stood before the angel. And he answered and spake unto those that stood before him, saying, Take away the filthy garments from him. And unto him he said, Behold, I have caused thine iniquity to pass from thee, and I will clothe thee with change of raiment” (Zechariah 3:3-4).
With these facts in mind, it makes perfect sense that the term “white” was rightly changed to “pure” in 2 Nephi 30:6. Moreover, knowing that the words can be used interchangeably clarifies Jacob’s declaration to the Nephites:
O all ye that are pure in heart, lift up your heads and receive the pleasing word of God, and feast upon his love . . . But, wo, wo, unto you that are not pure in heart, that are filthy this day before God; for except ye repent the land is cursed for your sakes; and the Lamanites, which are not filthy like unto you, nevertheless they are cursed with a sore cursing, shall scourge you even unto destruction . . . Behold, the Lamanites your brethren, whom ye hate because of their filthiness and the cursing which hath come upon their skins, are more righteous than you . . . O my brethren, I fear that unless ye shall repent of your sins that their skins will be whiter than yours, when ye shall be brought with them before the throne of God. Wherefore, a commandment I give unto you, which is the word of God, that ye revile no more against them because of the darkness of their skins; neither shall ye revile against them because of their filthiness; but ye shall remember your own filthiness, and remember that their filthiness came because of their fathers. (Jacob 3:2-3, 5, 8-9)
Here we read that some of the Nephites were “pure” and others were “filthy,” while the Lamanites, even with their darker skin, were “not filthy” and were “more righteous” than those of the Nephites who were filthy. Jacob’s brother, Nephi, wrote of the Lamanites becoming “a dark, and loathsome, and a filthy people, full of idleness and all manner of abominations” (1 Nephi 12:23). Similarly, Mormon wrote of the Nephites (whose skin color was not changed), “this people shall be scattered, and shall become a dark, a filthy, and a loathsome people, beyond the description of that which ever hath been amongst us, yea, even that which hath been among the Lamanites, and this because of their unbelief and idolatry” (Mormon 5:15). Both passages refer to the sinful state of the people, not their skin color. This is also supported by Moroni’s description of the Nephites: “And only a few years have passed away, and they were a civil and a delightsome people.” Passages like these verify Nephi’s teaching that the Lord “denieth none that come unto him, black and white, bond and free, male and female; and he remembereth the heathen; and all are alike unto God, both Jew and Gentile” (2 Nephi 26:33).
