Although speaking from a Latin understanding which supports all ECFās, Saints and Martyrs, who write; That the Essence of God does not proceed, when it is the Trinity of persons in Presence who proceeds divine revelation to be known.
Right, its a matter of discerning the language, same with the begotten Son and Spirit which proceeds. This is dogma of our Church [both Churches] which again is indicative of human analogy or procreation which or course isnāt reality with God. The language also can give the impression of a dual procession misunderstooding, which isnāt limited to Rome but polemics would like to attribute it to Rome, hence its the Creed. Here too St Thomas used cause and effect as his second of 5-points in elaboration of the existence of God. The argument is simple and leaves little room for rebuttal so its used even today in consistency such as in the apologeticās area. For example lets look at the Creed which one can easily arrive at a dual procession.
We believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible;
And in one Lord Jesus Christ, the Son of God, the Only-begotten, Begotten of the Father before all ages, Light of Light, Very God of Very God, Begotten, not made; of one essence with the Father, by whom all things were made:
Who for us men and for our salvation came down from heaven, and was incarnate of the Holy Spirit and the Virgin Mary, and was made man;
And was crucified also for us under Pontius Pilate, and suffered and was buried;
And the third day He rose again, according to the Scriptures;
And ascended into heaven, and sits at the right hand of the Father;
And He shall come again with glory to judge the living and the dead, Whose kingdom shall have no end.
And we believe in the Holy Spirit, the Lord, and Giver of Life, Who proceeds from the Father, Who with the Father and the Son together is worshipped and glorified, Who spoke by the Prophets;
And we believe in one, holy, catholic, and apostolic Church.
We acknowledge one Baptism for the remission of sins.
We look for the Resurrection of the dead,
And the Life of the age to come. Amen.
Through the Son is understood as; The Father sends the Son: the Father and the Son send the Holy Spirit, the Son isnāt a vessel which Divinity passed through in a non active role. This understanding is disturbing as it reminds me of fringe protestant thinking with the Incarnation and Christ[God] Nature defined at Council. Thus again with the gospel of John- He will glorify me because it is from me that he will receive what he will make known to you. All that belongs to the Father is mine. That is why I said the Spirit will receive from me what he will make known to you."
In God there are Three Persons, the Father, the Son and the Holy Ghost. Each of the Three Persons possesses the one (numerical) Divine Essence. (De fide.) The Divine Persons, not the Divine Nature, are the subject of the Internal Divine processions (in the active and in the passive sense). (De fide.) But there is āONEā Divine Essence of which all have. We use numerical order to understand the monarchy of the Father, who as Augustine state in the CCC reference is the first principle without principle. Which if I remember is out of his work on the Trinity in the footnotes.
So for us its a matter of understanding first what is infallible to synthesis all this. Which in all honesty is why Randy and few others suggest reading Ludwig for fundamental doctrinal understanding For example we follow thisā¦
- In God there are two Internal āDivine Processionsā. (De fide.)
- The Divine Persons, not the Divine Nature, are the subject of the Internal Divine processions (in the active and in the passive sense). (De fide.)
- The Second Divine Person proceeds from the First Divine Person by Generation, and therefore is related to Him as Son to a Father. (De fide.)
- The Holy Ghost proceeds from the Father and from the Son as from a Single Principle through a Single Spiration. (De fide.)
- The Holy Ghost does not proceed through generation but through spiration. (De. fide.)
And again as St Thomas explains in the highest sense this participation would be generation but not in any way corporal but spiritual, āsince the divine intelligence is of the highest perfection, it is necessary that the divine word be perfectly one with Him from whom He proceeds without any diversity of Nature.ā
This can be further read where its much deeper elaborated on for example in The Trinity by Garrigou Lagrange pg 93.
However, point being the teachings begin with the Creed with has infallible implications.
Interesting enough aside from the polemics the doctrine of Father and Son isā¦
The Father sends the Son: the Father and the Son send the Holy Ghost. (Sent. certa.)
This is infallible but has not been formally elevated yet to the level of De Fide, with respect to the dialogue of the East.
So while Rome is elaborating from the West, its mindful of the āusā as in East-West. Which anyone following Aquinas will quickly realize, he doesnāt disregard the Fathers but corrects language which is misleading and distracting. The Fathers digress to Rome as Augustine did in Retractions, they knew contemplation of discernment would continue. And it has as for example with Essence and Energies. Thus its not a matter of changing the truth which we have been saying, but clarification of the truth.
Anyway, not to further complicate a complicated teaching.
