Revelation 22:18-19
King James Version (KJV)
18For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:
19And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.
Luvtosew,
This does refer to all of Holy Scripture; but not in the way you are asserting.
It applies to all of Scripture in that we are not to alter God’s Word by adding to it or taking away from it, lest we be found a liar:
Proverbs 30:
5 Every word of God proves true;
he is a shield to those who take refuge in him.
6 Do not add to his words,
lest he rebuke you and you be found a liar.
In addition to the verses from Revelation you quoted; you will find a similar warning here:
Deuteronomy Chapter 4: 2
You shall not add to the word that I command you, nor take from it, that you may keep the commandments of the Lord your God that I command you.
After God gave specific instructions to Israel about what they were to do and not to do; He said:
Deuteronomy Chapter 12:
32 Everything that I command you, you shall be careful to do. You shall not add to it or take from it.
If we applied to the words in Deuteronomy, the same assertion you are making with Revelation; we would have to disregard all the teachings and commandments of Christ that did not precisely match Jewish law.
Obeying the Commandments of God, whether under the New Covenant or the Old Covenant is extremely important:
Deuteronomy 28: 45 “All these curses shall come upon you and pursue you and overtake you till you are destroyed, because you did not obey the voice of the Lord your God, to keep his commandments and his statutes that he commanded you.
When you study the transmission of Scripture; you will find that there has always been a problem with man attempting to alter Holy Scripture, whether it be ancient scribes or modern day translators.
God rebukes His people in Jeremiah and speaks of the
lying pen of the scribes (scribes were copyists):
Jeremiah 8:
7 Even the stork in the heavens
knows her times,
and the turtledove, swallow, and crane
keep the time of their coming,
but my people know not
the rules of the Lord.
8 “How can you say, ‘We are wise,
and the law of the Lord is with us’?
But
behold, the lying pen of the scribes
has made it into a lie.
9 The wise men shall be put to shame;
they shall be dismayed and taken;
behold, they have rejected the word of the Lord,
so what wisdom is in them?.
Some scribes decided to give their theological view a boost and inserted or removed things when copying N.T. autographs and manuscripts. Several of these are found in the KJV, btw.
Most of the obvious intentional changes have been discovered and corrected in many (not all) of the Bible translations we have today.
Keep in mind there are more than 5,000 manuscripts of the New Testament (copies of copies of copies), with more variants than words in the New Testament. Most variants are obvious scribal errors, such as missing a line; or copying into the main body of text, notes that were scribbled in the margins of Holy Scripture.
Some manuscripts contain scathing comments by authors, who found their writing altered by a scribe.
The author of Revelation is making it very clear that not one word of his writing is to be altered.
The whole point is that were are not to alter Holy Scripture, the Divinely inspired Word of God.
Peace,
Anna
