[The original is: “propter principii commendationem,” which the English translator renders “On account of commending to our thoughts the principle [of the Godhead].” The technical use of “principium” is missed. Augustin says that the phrases, “sending the Son,” and “sending the Spirit,” have reference to the “visible creature” through which in the theophanies each was manifested; but still more, to the fact that the Father is the “beginning” of the Son, and the Father and Son are the “beginning” of the Spirit. This fact of a “beginning,” or emanation (manatio) of one from another, is what is commended to our thoughts.—W.G.T.S.]
