Dear brother Alex,
I hate to do this (apologies to the OP

)-
I partly agree, partly disagree.
What I mean is this:
The fact is that the Latin understanding of Procession is different from the Greek understanding of Procession. To the Latins, Procession refers to the transmission of Divinity. To the Greeks, Procession refers to the hypostatic Origin of the Holy Spirit.
Both East and West agree that there is only one Souce of the hypostatic Origin of the Holy Spirit - namely, the Father.
Both East and West
also agree that the Divinity of the Holy Spirit comes from the Father and the Son (or through the Son). I don’t understand how you can say this is a mere theologoumenon, since it is a universal belief of the Church from times past (held everywhere and always).
The issue is ultimately not about the use or removal of
filioque from a
local version of the Creed. Nor is it about the theology of
filioque. Rather, we need to reflect on the difference in understanding on the nature of Divinity. To the East, Divinity is seen as an Energy of God, distinguishable from his Essence. But to the West, Divinity
is the Essence of God (I think the Orient is somewhat stuck between both positions).
It is really on this issue - the nature of Divinity - on which East and West are distinguishable, as far as this topic is concerned. The question is - can we accept each others’ position as equally valid and orthodox (West - Divinity is Essence; East - Divinity is Energy), or can we live together with that distinction? I don’t think either side has the monopoly on knowledge of Divinity. Both groups have to admit that we see through a glass darkly on this matter of Divinity as Essence or Energy, and have no right to rigidly impose either view at the expense of Unity.
Blessings,
Marduk
