Is 'Filioque' still a deal breaker for the Orthodox? Perhaps not. In 2003 the North American Orthodox-Catholic Theological Consultation produced: The Filioque: A Church-Dividing Issue? The document recommended the following:
1. That all involved in such dialogue expressly recognize the limitations of our ability to make definitive assertions about the inner life of God.All in all, it seems that the commission believes that the Filioque clause is no longer a "a Church dividing issue". Of course, it remains to be seen if the monks at Mt. Athos will sign on the dotted line and join in on the ecumenical group hug.
2. That, in the future, because of the progress in mutual understanding that has come about in recent decades, Orthodox and Catholics refrain from labeling as heretical the traditions of the other side on the subject of the procession of the Holy Spirit.
3. That Orthodox and Catholic theologians distinguish more clearly between the divinity and hypostatic identity of the Holy Spirit (which is a received dogma of our Churches) and the manner of the Spirit's origin, which still awaits full and final ecumenical resolution.
4. That those engaged in dialogue on this issue distinguish, as far as possible, the theological issues of the origin of the Holy Spirit from the ecclesiological issues of primacy and doctrinal authority in the Church, even as we pursue both questions seriously, together.
5. That the theological dialogue between our Churches also give careful consideration to the status of later councils held in both our Churches after those seven generally received as ecumenical.
6. That the Catholic Church, as a consequence of the normative and irrevocable dogmatic value of the Creed of 381, use the original Greek text alone in making translations of that Creed for catechetical and liturgical use.
7. That the Catholic Church, following a growing theological consensus, and in particular the statements made by Pope Paul VI, declare that the condemnation made at the Second Council of Lyons (1274) of those "who presume to deny that the Holy Spirit proceeds eternally from the Father and the Son" is no longer applicable.
