So, that promise & warning in Revelations was strictly for the book(or scroll as it were) of Revelations.
Then just answer why Joseph Smith added so many words to the book of Revelation in the JST "version" of the Bible.
Good point. But is there a difference between adding & restoring? Also, the warning has to do w/ man adding. What if the Lord wanted to add or restore? Could he do so through a prophet? Is He bound by that warning? Remember even though Moses produced the Ten Commandments, they were the Lords words & at his behest.
Well ... first of all, there is only the LDS claim ... apart from all Christians ... that anything was lost from any scriptures ... let alone from Revelations.
For the LDS to make such a claim, ... it is only to be expected that the claim be proven. Demonstrate exactly what was lost from the scriptures, when and how.
The rather feeble argument that it's possible doesn't prove anything. If you claim to have the authority to restore ... then you should be able to prove your claim.
When Jesus came and prompted the addition of new scripture ... He demonstrated His authority by His miraculous works which were acknowledged by all familiar with Him, whether friend or foe.John 14:11 Believe me when I say that I am in the Father and the Father is in me; or at least believe on the evidence of the works themselves.If God wished again to add (or restore) to His scriptures ... it would be expected that He would demonstrate authority in the one (prophet or other) assigned to the task.
Also note that even though Moses presented the Ten Commandments (along with the remainder of the OT Law) ... he had no authority to add to it.
REVELATION 12: 1-17
1 And there appeared a great sign in heaven, in the likeness of things on the earth; a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars.
2 And the woman being with child, cried, travailing in birth, and pained to be delivered.
3 And she brought for a man child, who was to rule all nations with a rod of iron; and her child was caught up unto God and his throne.
4 And there appeared another sign in heaven; and behold, a great red dragon, having seven heads and ten horns, and seven crowns upon his heads. And his tail drew the third part of the stars of heaven, and did cast them to the earth. And the dragon stood before the woman which was delivered, ready to devour her child after it was born.
5 And the woman fled into the wilderness, where she had a place prepared of God, that they should feed her there a thousand two hundred and threescore years.
6 And there was war in heaven; Michael and his angels fought against the dragon; and the dragon and his angels fought against Michael;
7 And the dragon prevailed not against Michael, neither the child, nor the woman which was the church of God, who had been delivered of her pains, and brought forth the kingdom of our God and his Christ.
8 Neither was there place found in heaven for the great dragon, who was cast out; that old serpent called the devil, and also called Satan, which deceiveth the whole world; he was cast out into earth; and his angels were cast out with him.
9 And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ;
10 For the accuser of our brethren is cast down, which accused them before our God day and night.
11 For they have overcome him by the blood of the Lamb, and by the word of their testimony; for they loved not their own lives, but kept the testimony even unto death. Therefore, rejoice O heavens, and ye that dwell in them.
12 And after these things I heard another voice saying, Woe to the inhabiters of the earth, yea, and they who dwell upon the islands of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
13 For when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child.
14 Therefore, to the woman were given two wings of a great eagle, that she might flee into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.
15 And the serpent casteth out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood.
16 And the earth helpeth the woman, and the earth openeth her mouth, and swalloweth up the flood which the dragon casteth out of his mouth.
17 Therefore, the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.

Have you not read the accounts of the miracles that Joseph Smith wrought? The prophecies that have come to pass? Joseph was not alone when he received the priesthood under the hands of Peter, James, & John. Joseph was not alone to witness the plates.
You are right to assert that Moses had no authority to change the commandments on his own but he did have the authority to change them under the direction of the Lord & this he did. Remember the first set? Did Moses not have authority to present the second set?
On a book that was compiled at the behest of the Roman Empire, I think it is up to your side to PROVE that it is all there. Are the original manuscripts still available?
