Moses was not a Christian...
Doesn't matter.
The claims that Jesus is the messiah are predicated on prophecies in the Hebrew texts.
However, the New Testament texts are in conflict.
1) #47 (Chester Beatty) circa 250 CE papyrus contains only Revelation 9:10-17:2 usually agreeing with
Codex Sinaiticus. This papyrus alone has over 40 lines of disputed text even though it covers only portions of six chapters of Revelation.
2) #75 (Bodmer) a circa 225 CE papyrus contains parts of Luke and John usually agreeing with
Codex Vaticanus but it conflicts with other sources.
3)
Codex Sinaiticus circa 350 CE.
This is the only complete version of the New Testament.
4) Codex Alexandrinus circa 450 CE. It is nearly complete and very close doctrinally to
Codex Sinaiticus, except for the Epistles. There are more than 40 disputed lines of text between
Codices Alexandrinus and
Sinaiticus.
5)
Codex Ephraemi Rescriptus circa 450 CE. Most of you wouldn’t even recognize this as the New Testament, we’re talking 100s of lines of disputed text. It contains portions of every book except for 2 Thessalonians and 2 John.
6)
Codex Regius circa 750 CE. Only the gospels. It most often agrees with
Codex Vaticanus. Again, several hundred lines of disputed text.
7)
Codex Washingtonianus circa 425 CE. A Byzantine work of portions of the gospels only. Parts of John appear to be copied from
Codex Alexandrinus.
8)
Codex Koridethi circa 850 CE. Gospel parts only. Parts of Mark appear to have been quoted from the works of Origen and Eusebius in the 3rd and 4th Centuries respectively.
9)
Codex Athous Laurae circa 900 CE. Contains parts of gospels, Acts, most of Paul and the Epistles. A mix of the Alexandrian, Western and Byzantine doctrines. Hundreds of lines of disputed text.

"Translators" -- and I do use the word loosely -- use those and other works to write their nonsense.
I won't even get into doctrines such as Coptic, Alexandrian, Western, Byzantine,
et al, because I already know that's way beyond your understanding.
