[The theophanies of the Pentateuch are trinitarian in their implication. They involve distinctions in God—God sending, and God sent; God speaking of God, and God speaking to God. The trinitarianism of the Old Testament has been lost sight of to some extent in the modern construction of the doctrine. The patristic, mediæval, and reformation theologies worked this vein with thoroughness, and the analysis of Augustin in this reference is worthy of careful study.—W.G.T.S.]
