Quotes from Johannes Scotus Eriugena

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.

Nemo intrat in caelum nisi per philosophiam

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.

Every visible and invisible creature is an appearance of God.

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.
