There is no abstract conceptual apparatus by which we can know the Christian God. Knowledge of God is absolutely contingent on God’s free Self-revelation in Jesus Christ. This is the only way as Christians that we know God; as the God of Abraham, Isaac, and Jacob. He has descended to us in the real garb of a flesh and blood human; as a Jew from Nazareth. And His reception in Mary’s womb was made fertile by the millennia of preparation for His first coming as the Holy Spirit hovered over the Hebrews.
None of the above requires augmentation by way of appeal to and appropriation of foreign and abstract metaphysics. The Christ child came in the wood of the manger; died on the wood of the cross; and rose again from the rock of the tomb. These are all concrete and particular materials that have no correspondence with the ethereal of the philosophers, per se.
