They are available on the internet. And they have indeed been altered, which is why when you do a manuscript comparison, you will arrive at this precise conclusion. Take a look at one of the verses here at Biblehub
1 John 5:7 For there are three that testify: , only around six render it in the false trinitarian form, because it only exists in manuscripts from around the
16th century and onwards. And the reason this was a forgery was because it serves a greater lie, the lie of the trinity that was forged unto that verse. Open your eyes.
Your scholarship is lacking teknon. Granted the "Trinity" took 3 centuries before it was promulgated by the council of Nicea. The Trinity had been know all along.
The Trinity has been known from the beginning.
The word for God in the very first passage of the Hebrew Bible uses the word Elohim (plural) for God
בְּרֵאשִׁית בָּרָא אֱלֹהִים אֵת הַשָּׁמַיִם וְאֵת הָאָֽרֶץ׃
The third word in from the RIGHT is Elohim - plural.
Then in verse 26
26 And God said, Let us make man in
our image, after
our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
27 So God created man in his own image, in the image of God created he him; male and female created he them.
Later the tetragrammaton (YHWH) was used together with Elohim YHWH-Elohim.

22 And the
LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
23 Therefore the
LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken.
24 So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life.
Lord God :
יְהוָה אֱלֹהִים
YHWH is a concatenation of the three tenses of "I was, I am, I will be" translated by the KJV translators as I AM or Jehovah or LORD (all uppercase).
YHWH (Jehovah) is a singular masculine noun.
Lord God YHWH-Elohim used together - God is a plurality of persons in one Godhead.
It was not until the advent of Jesus Christ the Logos the second person of the Trinity that we were given the full definition of the Trinitarian Godhead.
John 1:18 No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him.
In the Great Commission:
Matthew 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
