St. Maximus the Confessor ca. 580-662
The grace of the New Testament is mystically hidden in the letter of the Old; thus, the Apostle says that “the Law is spiritual” (Rom. 7:14). The Law, consequently, although in the letter it ages and grows old when not being practiced (cf. Heb. 8:13), nevertheless in the spirit it constantly grows young, being energized. For grace is absolutely unaging. (Two Hundred Chapters on Theology, 1.89)
