God gave both the Hebrew covenants and Greek philosophy

And further, that the same God that furnished both the Covenants was the giver of Greek philosophy to the Greeks, by which the Almighty is glorified among the Greeks, he shows.

…But as the proclamation [of the Gospel] has come now at the fit time, so also at the fit time were the Law and the Prophets given to the Barbarians, and Philosophy to the Greeks, to fit their ears for the Gospel.

Early admonitions against racism

And it prohibits an ox and ass to be yoked in the plough together; pointing perhaps to the want of agreement in the case of the animals; and at the same time teaching not to wrong any one belonging to another race, and bring him under the yoke, when there is no other cause to allege than difference of race, which is no cause at all, being neither wickedness nor the effect of wickedness.

This you did yourself at the commencement of the discourse, when you declared that I would not be saved unless I observe these institutions.”
