Augustine of Hippo — as excerpted in the Catena Aurea on John 1:1

“(de Verb. Dom. Serm. 38) Now the Word of God is a Form, not a formation, but the Form of all forms, a Form unchangeable, removed from accident, from failure, from time, from space, surpassing all things, and existing in all things as a kind of foundation underneath, and summit above them.”
