God’s Word Won’t Pass Away
D&C 1:38-39; “What I the Lord have spoken, I have spoken, and I excuse not myself; and though the heavens and the earth pass away, my word shall not pass away, but shall all be fulfilled, whether by mine own voice or by the voice of my servants, it is the same. 39 For behold, and lo, the Lord is God, and the Spirit beareth record, and the record is true, and the truth abideth forever and ever. Amen.”

I wouldn’t be able to count the number of changes that have been made in the Doctrine and Covenants alone. You can do a side by side comparison of the two books (D&C & Book of Commandments) to see for yourself but plan on being at your desk for a long while. This doesn’t even account for the changes made in the Book of Mormon (4,000).
There has been no change in meaning, however, which is really all that matters.
You can start with 2 Nephi 30:6. That one example alone tells me your statement isn’t correct. The word pure in that verse used to say white. The entire meaning of that verse was changed when they did this in 1981.
God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, hath in these last days spoken unto us by his Son
LIFE
In the 1800’s the term white was frequently used to describe something that was pure, just as black was used to describe that which was defiled. I have read others use the terms in this way. This was taken largely from the Imagery of Isaiah when he states that though your sins be as scarlet they will be as white as snow; and obvious allusion to purity.
As such, the meaning is not changed, but is an update of language, since this use is no longer in practice. Rather than use the imagery of white, the meaning of the imagery is used instead.
The meaning of 2 Nephi 30: 6 has always been a cleansing of the soul and living a righteous life. This unchanged.
