Why does Emperor Julian praise Yahweh?

[Null Sechs]

If he wrote it he could have written it for diplomacy or it's a mistake in translation

 

[Wisdom_Seeker]

The Christians have often tried very hard to alter texts to make the writer seem supportive of their cult. They couldn't write into his manuscripts that he liked them because he persecuted them but they could write in that he liked Yahweh and that the Old Testament patriarchs were great and then they could use that to say that Julian just didn't know we the Christians were the true yehuborim all along

That is definitely possible, and it would not be the first nor the last time they did it. There is also a supposed quote of him "admitting" that the Galilean won. The majority of stories surrounding the saintly figures are fables and exaggerations.
