Cyril of Alexandria

For those who had never seen Christ on account of residing in gloom and darkness called on him, that is, they acknowledged Jesus as God and fled to him calling him their hope and shelter and means of salvation and called on him as God … for although according to the measure of humanity Christ was thought to be ignoble, he went back to that which was appropriate to him and divine and the highest glory—but not without his flesh.

Thomas Aquinas

And what may be done for them: behold you shall call nations, to fulfill your command, not by your own power, but because of the Lord, above: and they shall adore for the sake of the Lord your God, who has chosen you (Isa 49:7).
