Dear brother JesusforMadrid,
A belief need not be dogmatized (set into a formal decree) in order for it to be dogmatic. A lot of EO (perhaps all) view the Essence/Energy distinction as a dogmatic principle.
Whether it is dogma is beside the point. The point is that it is regarded as a dogmatic principle by many (if not all) EO by which many judge the merit of Latin teachings. And it’s not just with regards to filioque. Another is in relation to the patristic teaching on the unity of God. The unity of God is a defined dogma in the Catholic Church; however, the Catholic Church has never utilized it in opposition to the Essence/Energy distinction. In contrast, many EO have dogmatized the Essence/Energy distinction to such an extent that they actually use it in opposition to the Latin concept of the unity of God.
The ultimate problem is that there are a lot of EO who utilize the Essence/Energy distinction as a basis for disunity with the Catholic Church. In the face of that, the claim that “it is not a dogma” seems like an empty platitude, especially as it is nevertheless held to be dogmatic, believed with the same zeal as if it was in fact a dogma (only without the name).
The problem is that there are way too many EO who utilize the filioque as a basis for division with the Catholic Church when it should not be.
Like I said, there might not be any new dogma, but there are things believed with the same dogmatic fervor. Another example is the issue of purgatorial fire. The Latins have never even dogmatized this matter, yet there are a lot of EO who view it as some sort of heresy. Though there is no dogma (a formal decree) about it, the zeal of the Easterns in opposition to it is nevertheless dogmatic. There are a LOT of issues on which the opposition of many Easterns has become dogmatic, so, again, the claim that “there has been no dogma” sounds like a hollow platitude.
Again, the opposition to these things from the EO have become just as dogmatic as the positive affirmation of these dogmas from the Catholic side. Among non-Latin Catholics, you can find criticisms and occasional arguments with our Latin brethren, but you won’t find non-Latin Catholics calling them heresies. You can rationalize that the EO have not made any new dogmas all you want, but the fact still remains that many EO actually do have a very dogmatic outlook on a lot of matters. The moment one says “that is a heresy,” one has made a dogmatic determination.
On the other hand, I have met EO, some of them members of CAF, who are more consistent with the apophatic phrenoma of the East, and don’t go around hurling accusations of heresy at Catholics, but try to engage in genuine dialogue.
Blessings,
