Brother Ryan. Can you not see that from the perspective of St. Gregory (and all the Fathers, actually), you cannot divorce in any way the concept of origination from the concept of co-divinity or consubstantiality? You claim that there were heretics who were making a point about the Spirit not originating from the Father. But isn’t it true that these heretics were denying said origin precisely because they were intent on denying the divinity of the Holy Spirit?
I agree that the concept of the origination of co-divinity/consubstantiality cannot be separated from the concept of origination. Also, after reading your last response to me, I think that we do not disagree to the degree that I thought. However, I think in some of your posts, you have minimized the extent to which the purpose of the language concerning the begetting of the Son by the Father and the procession of the Spirit from the Father serve the purpose of explaining the relationships among the three divine hypostases and the manner in which the Son and the Spirit originate from the Father.
There is a great degree of scholarly agreement that St. Gregory of Nazianzus and St. Gregory of Nyssa were pivotal in the workings of the Second Ecumenical Council, and through their presence, so was St. Basil the Great, who had died prior to the Council. There is also a great deal of scholarly agreement that the three Cappadocian Fathers used the language of the procession of the Spirit from the Father exactly for the purpose of distinguishing the manner in which the Spirit originates from the Father from the manner in which the Son originates from the Father. This is why I continue to insist that the primary purpose of the language of the procession of the Spirit from the Father is to show the manner in which the Spirit originates from the Father.
The consubstantiality of the Holy Spirit had, as I believe you are aware, been taught by multiple local synods prior to the Second Ecumenical Council. Also, it had been defended in writings of numerous Church Fathers, both Latin and Greek. In some sense, the issue was likely already settled in the minds of the Fathers of the Second Ecumenical Council (it certainly was in the minds of the Cappadocian Fathers). It is my contention that the consubstantiality of the Spirit was demonstrated
primarily by the language of “the Lord, the Giver of life” and “who together with the Father and the Son is worshipped and glorified,” as well as by various authoritative writings leading up to the Second Ecumenical Council that actually used the term “consubstantial.” I further contend that the consubstantiality of the Spirit is demonstrated
secondarily by the language concerning the origination of the Spirit from the Father, insofar as the (eternal) origination of the Holy Spirit from the divine life of the Father implies his consubstantiality with the Father. On the other hand, I contend, on the basis of the writings of the Cappadocian Fathers themselves, the language of the CCC, and the work of scholars, that the language of procession
primarily concerns the origination of the Holy Spirit from the Father and how it differs from that of the Son, while it
secondarily demonstrates the consubstantiality of the Spirit with the Father (and the Son).
So, I do not disagree with you that the origination of the Son and the Spirit from the Father is inextricably linked to their consubstantiality with the Father; otherwise, one could not maintain the monarchia and/or arche of the Father. In other words, if, as the Gospel of John teaches, the Father is in some sense “greater” than the Son (and the Spirit), but Father, Son, and Holy Spirit are consubstantial, then it must be the case that the Son and the Spirit originate from the Father (ontologically, though not temporally, since they are co-eternal with the Father).
