The Divine Trinity - the greatest of all Christian mysteries. How is it that the one God is a unity of three divine persons? Christ-Jesus first revealed this mystery to his disciples when on earth. Later, around the sixth century, the Trinitarian mystery was theologically clarified and outlined by the formulation of the Athanasian Creed. Conceptual understanding of the divine Trinity has changed very little in Western society since then. Similarly with the theological understanding of the Logos-Word as mentioned in the Gospel of St. John. The traditional understanding that has remained essentially unchallenged for centuries is that the Logos-Word is synonymous with God the Son. As for creation, the best that mainstream Christianity has historically provided is an ancient, allegorical account contained in the Book of Genesis. Out of the hidden well-springs of esoteric Christianity, and as the title indicates, "The Greater Mysteries of the Divine Trinity, the Logos-Word and Creation" delves much more deeply into the profound mysteries of the Trinitarian God, the Logos-Word of St. John and the creation of the universe. The divine Trinity is here demonstrated to be the loving union of Heavenly Father, Holy Mother and Eternal Son. The Logos-Word is here evidenced to be the "Universal Man," the primordial, cosmic creation of God the Son. Universal creation itself is here detailed to be the "one life becoming many" - the multiplication of the Logos-Word into countless, individualized life-forms and beings. The depth and breadth of original and thought-provoking information presented here will, no doubt, stimulate and excite those esoteric thinkers who are seriously seeking answers to the deeper mysteries of life, existence and the universe.
