Dear sharpag,
I agreed with a great deal of what you said; however, I must disagree with your claim that the filioque does not address the origin of the Trinity. Procession is most definitely a term of origination. I don’t think it’s fair to say this is just the Easterners being Eastern. While the filioque does address the essence of the Trinity (as you rightly pointed out), it also addresses the economic origin. In what other circumstance is the procession of the Holy Spirit mentioned without applying to the economy of the Trinity or to origination?
The sending of the Holy Spirit is not thought of in terms of origin in the Latin Tradition. The sending occurs, in the Latin Tradition, not because the Son is origin, but because the Spirit shares what the Son has from the Father. It is a matter of sharing, not a matter of originating.
The concept of originating is a peculiarly Eastern theological principle that should not be imposed on the Latin concept simply because later Latin authorities had to make a definition to explain the matter in terms of origin for the benefit of the Easterns.
To the Latins, the phrase “Proceeding from the Father” was a statement about the consubstantiality. Hence, to them, it was perfectly fine to add “and the Son” because the Spirit is, in the fullness of orthodox Truth, consubstantial with the Father
AND the Son. This is perhaps why a some Latins would have accused the Easterns of heresy in denying
filioque. To Latins, it would mean denying the consubstantiality of the Spirit with the Father
AND the Son. Of course, those particular Latins would have misunderstood that the Easterns were coming from a different theological presupposition - namely, that “proceeding from the Father” was a statement about origination, not consubstantiality.
Not correcting, just explaining.
If the filioque really is about the unity of the Trinity why is it 1) in an economic phrase
That is imposing an Eastern outlook on the Latin paradigm. Unlike the Eastern paradigm, the Latins do not make a distinction between Essence and Energy. The Energetic economy is not conceived of separately from the Essential divinity in the Latin Tradition. So to speak of the Economic procession as something distinct from considerations of Essence in trying to understand
filioque from the Latin perspective would be improper.
- after the Son is already said to be of the same being as the Father as He is “true God of true God”?
To the Latins, to combat a certain brand of Arianism in their lands, that the Son is consubstantial with the Father COULD still make the Son subordinate to the Father if it was not equally affirmed that the Son was consubstantial with the Spirit (who is consubstantial with the Father). It is, after all, the common consubstantiality of the three Persons that make them all equally God.
