The Greek theologians, founding on the primary sense of the Greek term Πνεῦμα, and on certain passages of Scripture in which the word seemed to retain that sense more or less (especially Psalm xxxiii. 6. in the Vulgate rendering, verbo Dei cœli formati sunt: et spiritu oris ejus omnis virtus eorum), spoke of the Holy Ghost as proceeding from the Father like the breath of His mouth in the utterance or emission of His Word. See ch. 15 of this Book, where we have the sentence, οὐδεμία γὰρ ὁρμὴ ἄνευ πνεύματος. Compare also such passages as these—Greg. Naz., Orat. i. 3: Cyril. Alex., Thes., assert. 34, De Trin. dial. 2, p. 425, and 7, pp. 634, 640; Basil, Contra Eunom., B.V., and De Spiritu Sancto, ch. 18; Greg. Scholar., Contra Latin., de process. Spiritus Sancti, i. 4, where we have the statement οὕτω καὶ τὸ ἅγιον Πνεῦμα ὥσπερ ὁρμὴ καὶ κίνησις, ἐνδοτέρα τῆς ὑπερφυοῦς ἐκείνης οὐσίας, so the Holy Spirit is like an impulse and movement within that supernatural essence.
