And although the breath of all this mighty and immeasurable power, and the vigor itself produced, so to speak, by its own existence, proceed from the power itself, as the will does from the mind, yet even this will of God is nevertheless made to become the power of God.
…And if he shall grant that there was once a beginning, when that breath proceeded from the power of God, we shall ask him again, why not even before the beginning, which he has allowed; and in this way, ever demanding an earlier date, and going upwards with our interrogations, we shall arrive at this conclusion, that as God was always possessed of power and will, there never was any reason of propriety or otherwise, why He may not have always possessed that blessing which He desired. By which it is shown that that breath of God’s power always existed, having no beginning save God Himself.
Origen
On First Principles
Chapter II
