Authority that is not confirmed by true reason seems weak. Whereas true reason does not need to be confirmed by any authority.

For authority proceeds from true reason, but reason certainly does not proceed from authority. For every authority which is not upheld by true reason is seen to be weak, whereas true reason is kept firm and immutable by her own powers and does not require to be confirmed by the assent of any authority.

We do not know what God is. God Himself does not know what He is because He is not anything. Literally God is not, because He transcends being.

Observe the forms and beauties of sensible things and comprehend the Word of God in them. If you do so, the truth will reveal to you in all such things only He who made them.

Christ wears two shoes in the world: scripture and nature. Both are necessary to understand the Lord, and at no stage can creation be seen as a separation of things from God.
