Thomas Aquinas's Summa theologiae Quotes

“Thomas seems to be implying a threefold, originally Neoplatonic, model that he would have known through the writings of Pseudo-Dionysius, comprising (1) God in God-self; (2) the exitus, or procession of creatures from God; and finally (3) the reditus, or the return of creatures to God.”
