Likewise we believe also in one Holy Spirit, the Lord and Giver of Life: Who proceedeth from the Father and resteth in the Son: the object of equal adoration and glorification with the Father and Son, since He is co-essential and co-eternal Greg. Naz., Orat. 37.: the Spirit of God, direct, authoritative ἡγεμονικόν., the fountain of wisdom, and life, and holiness: God existing and addressed along with Father and Son: uncreate, full, creative, all-ruling, all-effecting, all-powerful, of infinite power, Lord of all creation and not under any lord Greg. Naz., Orat. 49.: deifying, not deified θεοῦν οὐ θεούμενον.: filling, not filled: shared in, not sharing in: sanctifying, not sanctified: the intercessor, receiving the supplications of all: in all things like to the Father and Son: proceeding from the Father and communicated through the Son, and participated in by all creation, through Himself creating, and investing with essence and sanctifying, and maintaining the universe: having subsistence, existing in its own proper and peculiar subsistence, inseparable and indivisible from Father and Son, and possessing all the qualities that the Father and Son possess, save that of not being begotten or born. For the Father is without cause and unborn: for He is derived from nothing, but derives from Himself His being, nor does He derive a single quality from another Text οὐ γὰρ ἔκ τινος· ἐξ ἑαυτοῦ γὰρ τὸ εἶναι ἔχει, οὐδέ τι τῶν ὅσαπερ ἔχει ἐξ ἑτέρου ἔχει· Another reading is, οὐ γὰρ ἔκ τινος τὸ ειναι ἔχει, οὐδέ τι τῶν οσα ἔχει, i.e. or He does not derive His being nor any one of His qualities from any one.. Rather He is Himself the beginning and cause of the existence of all things in a definite and natural manner. But the Son is derived from the Father after the manner of generation, and the Holy Spirit likewise is derived from the Father, yet not after the manner of generation, but after that of procession. And we have learned that there is a difference See Greg. Naz., Orat. 29, 35; Thomas Aquin., I. Quæst. 35, art. 1. between generation and procession, but the nature of that difference we in no wise understand. Further, the generation of the Son from the Father and the procession of the Holy Spirit are simultaneous.
