Gregg Allison, Ph.D.: "Historical Theology," Ch. 11--Trinity, 238ff.
Augustine as well as the Cappadocian Fathers—Basil the Great, Gregory of Nyssa, and Gregory of Nazianzus—bring further support and clarification, including the now-tossed-off Athanasian Creed. Am afraid a Trinitarian consciousness is nearwise gone, except for the schools, books, and seminaries. Thankfully, Prayer Book Churchmanship certainly helps to conserve and advance Trinitarianism, not leaving it to some cleric "to wing it." And also, our glorious Reformed Confessions. Some hymns helps too. Also, "Trinity Season." Time to be a part of the solution and not the problem. A retour.
