Pseudo-Dionysius: "Most divine of all sacraments"

“Do thou, O holy Sacrament, most divine of all sacraments, lift the veils that envelope Thee with their symbols, reveal Thyself clearly to our sight, and fill the eyes of our mind with a unifying and clear light!”

~Pseudo-Dionysius the Areopagite (6th cent.): Ecclesiastical Hierarchy, 3, 3.
