On the Holy Trinity — Historical footnotes

48. But because it is most difficult to distinguish generation from procession in that co-eternal, and equal, and incorporeal, and ineffably unchangeable and indivisible Trinity, let it suffice meanwhile to put before those who are not able to be drawn on further, what we said upon this subject in a sermon to be delivered in the ears of Christian people, and after saying wrote it down. For when, among other things, I had taught them by testimonies of the Holy Scriptures that the Holy Spirit proceeds from both, I continue: “If, then, the Holy Spirit proceeds both from the Father and from the Son, why did the Son say, ‘He proceedeth from the Father?’ Why, think you, except as He is wont to refer to Him, that also which is His own, from whom also He Himself is? Whence also is that which He saith, ‘My doctrine is not mine own, but His that sent me?’ If, therefore, it is His doctrine that is here understood, which yet He said was not His own, but His that sent Him, how much more is it there to be understood that the Holy Spirit proceeds also from Himself, where He so says, He proceedeth from the Father, as not to say, He proceedeth not from me? From Him, certainly, from whom the Son had his Divine nature, for He is God of God, He has also, that from Him too proceeds the Holy Spirit; and hence the Holy Spirit has from the Father Himself, that He should proceed from the Son also, as He proceeds from the Father. Here, too, in some way may this also be understood, so far as it can be understood by such as we are, why the Holy Spirit is not said to be born, but rather to proceed; since if He, too, was called a Son, He would certainly be called the Son of both, which is most absurd, since no one is son of two, save of father and mother. But far be it from us to surmise any such thing as this between God the Father and God the Son. Because not even the son of men proceeds at the same time from both father and mother; but when he proceeds from the father into the mother, he does not at that time proceed from the mother; and when he proceeds from the mother into this present light, he does not at that time proceed from the father. But the Holy Spirit does not proceed from the Father into the Son, and from the Son proceed to sanctify the creature, but proceeds at once from both; although the Father has given this to the Son, that He should proceed, as from Himself, so also from Him. For we cannot say that the Holy Spirit is not life, while the Father is life, and the Son is life: and hence as the Father, while He has life in Himself, has given also to the Son to have life in Himself; so has He given also to Him that life should proceed from Him, as it also proceeds from Himself.” I have transferred this from that sermon into this book, but I was speaking to believers, not to unbelievers.
