Hilary of Poitiers

The Lord has declared: “If I do not perform the works of my Father do not believe me.” Hence, he teaches that the Father is seen in him because he performs his works so that the power of the nature that was perceived would reveal the nature of the power that was perceived, wherefore the apostle, indicating that this is the image of God, says: “Who is the image of the invisible God … that through him he should reconcile all things to himself.” Accordingly, he is the image of God by the power of these works.

There is no doubt that all things are through the Son, since, according to the apostle, “All things are through him and in him.” If all things are through him, and all things are from nothing, and nothing is except through him, I ask in what way does he lack the true nature of God, since he is not lacking either in the nature or the power of God? For he used the power of his nature that these things should exist which had no existence, and that these things should exist which pleased him.
