That is why Paul received revelation from the Lord so he could teach the Gospel of Jesus Christ.
Something to ponder sense it was an on going challenge in those days to keep the word of the Lord intact as Jesus made know in Gal 1.
There was 1800 years of opportunity to edit and revise the scriptures according the government in office.
That was why there was needed in the last day a restoration OF ALL things
Gal 1
6 I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:
7 Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.
8 But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.
9 As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
10 For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ.
11 But I certify you, brethren, that the gospel which was preached of me is not after man.
12 For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.
That angel in Gal 1;8, had nothing to do with the latter day’s restoration
Revelation 14
5 And in their mouth was found no guile: for they are without fault before the throne of God.
6 And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people,
Hebrews 13:8-9
Jesus Christ is the same yesterday and today and forever.
Do not be carried away by all kinds of strange teachings. It is good for our hearts to be strengthened by grace, not by ceremonial foods, which are of no value to those who eat them.
"Jesus Christ is the same yesterday and today and forever."
Some honest-hearted reading of Hebrews, Ephesians, Colossians 1, John 1, and Isaiah 53 may be in order, for any who believe in any requirement for "progressive" revelation -- or that Jesus, Omnipotent God in Human Flesh didn't know "from the foundation of the world" just who he was, what he was doing, why he was doing it, and what the outcome would be.
"In Him all things hold together." Nothing else is necessary, when you have God.
