Tertullian

“ Much more will “the power of the Highest” not be the Highest Himself, because It is not an actually existing thing, as being Spirit—in the same way as the wisdom (of God) and the providence (of God) is not God: these attributes are not substances, but the accidents of the particular substance. Power is incidental to the Spirit, but cannot itself be the Spirit. These things, therefore, whatsoever they are— (I mean) the Spirit of God, and the Word and the Power—having been conferred on the Virgin, that which is born of her is the Son of God. ”

“ On this passage even they will wish to raise a cavil; but truth will prevail. Of course, they say, the Son of God is God, and the power of the highest is the Most High. And they do not hesitate to insinuate [2] what, if it had been true, would have been written. ”
