Origen

The power of choosing good and evil is within the reach of all.

— Origen

Having refuted, then, as well as we could, every notion which might suggest that we were to think of God as in any degree corporeal, we go on to say that, according to strict truth, God is incomprehensible, and incapable of being measured. For whatever be the knowledge which we are able to obtain of God, either by perception or reflection, we must of necessity believe that He is by many degrees far better than what we perceive Him to be.

— Origen

Every being which is endowed with reason, and transgresses its statutes and limitations, is undoubtedly involved in sin by swerving from rectitude and justice.

— Origen

As the eye naturally seeks the light and vision, and our body naturally desires food and drink, so our mind is possessed with a becoming and natural desire to become acquainted with the truth of God and the causes of things.

— Origen

The reason why all those we have mentioned hold false opinions and make impious or ignorant assertions about God appears to be nothing else but this, that scripture is not understood in its spiritual sense, but is interpreted according to the bare letter.

— Origen

As for the apostolic epistles, what person who is skilled in literary interpretation would think them to be plain and easily understood, when even in them there are thousands of passages that provide, as it through a window, a narrow opening leading to multitudes of the deepest thoughts?

— Origen

Now the true soldiers of Christ must always be prepared to do battle for the truth, and must never, so far as lies with them, allow false convictions to creep in.

— Origen
