Dear Friends,
Discussions on the Filioque can, and have, filled many volumes!
That being said, we are blessed to live in irenical times. The great work of Father Francis Dvornik on the East-West divide has brought to light a number of important things that were lost in the previous centuries of polemical infighting (most notably, that Photios, Patriarch of Constantinople, died in union with Rome and he is honoured today as a saint by many Eastern Catholics as well as by Orthodox).
On one level, there is the issue of the inclusion of the Filioque in the Nicene Creed. Perhaps both East and West could agree on the original text of the Creed that did not have the Filioque. The Venerable Pope John Paul II would leave the Filioque out whenever he served the Mass in Greek. The removal of the Filioque by the West would in no wise mean that the West is giving up its legitimate theological heritage on this point either.
Both East and West agree that the Holy Spirit proceeds in time from both the Father and the Son. They both send the Spirit. Eastern texts proclaim that the Holy Spirit “Proceeds from the Father and rests on the Son” or “Proceeds from the Father and is sent by Jesus Christ” etc.
With respect to the eternal procession of the Spirit, even if it can be demonstrated from the Scholastic perspective that the Spirit proceeds from the Son as He does from the Father - there is still the need for a qualifier with respect to His procession from the Son. I’ve read Roman Catholic texts that indicate that the Spirit proceeds “passively” from the Son but “actively” from the Father (similar to the “from the Father through the Son” in the East although this term refers entirely to the Spirit’s temporal procession).
Where the discussion tends to break down is on the point of whether an explicit acknowledgement of the Spirit’s procession f(in eternal terms) from the Son is necessary in order to maintain the “distinctiveness” of the Spirit from the Son. The West has traditionally affirmed this while the East has disagreed. However, both East and West agree that the manner of the Son’s being Begotten of the Father and the Spirit’s procession from the Father are distinctly different - if completely mysterious and unknown as to the “how.” The East is content to leave the matter as a mystery, while the West would prefer to go further.
In that case, since there already is agreement on this point - why not use that as the basis for unity and leave all else to the theologoumenon traditions of each Church? The Filioque can be understood as a theological viewpoint in the West which is simply that and something that should not be required of the Eastern Churches for unity on the important issue of Triadology/Trinitarian theology.
