Leolaia (again),
There is also an interesting Petrine tradition about the church itself as being a "different race," of Christianity as the "third way" (neither Jew nor Gentile)....
The "different race" theme is certainly given a rather different application in the Petrine pseudepigrapha, but it still looks like a thread that runs between distinct groups of Christian literatures....btw, the Petrine idea of Christians as a "third race" is not ideologically one of including Gentiles into the Jewish fold but rather creating a new race that was neither Jewish nor Gentile.
A different (or another) race I clearly see in both biblical and extra-biblical writings. But, forgive me if I didn't check all your references (and I didn't/ have time), but I've never read in any of these texts about a "third race."
The literature speaks about "births" (or being born into a race) and I've identified "Two Races" that seem to be consistent throughout all of the literature (biblical and non-biblical). This is a theme that seems to be somewhat "unknown" (for lack of vocabulary). But it's apparent to me.
I refer you back to my post where quoted from 1 Enoch and the Gospel of John:
(and echoing back to an earlier text)
1 Enoch 39
1. And it shall come to pass in those days that elect and holy children will descend from the
2. high heaven, and their seed will become one with the children of men.
Odes of Solomon 31
4. Then He lifted his voice towards the Most High, and offered to Him those that had become sons through Him.
John 1 (NKJV)
10. He was in the world, and the world was made through Him, and the world did not know Him.
11. He came to His own, and His own did not receive Him.
12. But as many as received Him, to them He gave the right to become children of God, to those who believe in His name:
13. who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
This might be a tad off-topic for the thread but, surely; I can't be the only person (around) who "sees this" can I?
