I’m not sure what you mean by “councils of their own”, but
here is a short listing of Orthodox councils, including pan-Orthodox councils (last one listed in 1627), local councils (last one listed 1872), and one inter-Orthodox congress (1927, about the calendar).
Not to sound too “Orthodox”-ish, but why? I was taught in RCIA only a few years ago that any official pronouncements of doctrine are made only in those cases when absolutely necessary, as to combat some
specific heresy or unacceptable practice, not because we had supposedly “learned more” about the subject at hand. This seems different to me than the assertion that our understanding is supposed to expand as a natural consequence of time and increased understanding about the world, or whatever it is you’re talking about here. I joined the Church with that original explanation in mind (to combat specific heresy, not merely “it’s supposed to happen this way”), and since then I have increasingly wondered if I wasn’t in fact sold a bit of a false picture of how things actually work. I much prefer the original parameters as they were explained to me, which seem much more in line with what I saw when browsing the above list. You know…actual reasons and whatnot.
Forgive me, but what is the difference between this and just making things up as you go along? I left Protestantism to get away from this kind of thinking, where things change on a fairly regular basis in accordance with one’s personal understanding of scripture and what you feel the Holy Spirit is telling you. More to the point, doesn’t a “faith journey” typically NOT include promulgation of doctrine binding on millions of faithful? Again, I guess since I have been under the impression so far that the development of doctrine in Catholicism involves something other than deciding to define what we had been happy to leave undefined
in the absence of a pressing need to define it just because, hey, we’re on a journey, I don’t really understand this kind of thinking.
God help me…I am so confused right now.
