"This talk of Tradition just seems, and it is not meant as an insult, but it seems to this interested observer, that the OC knows if the RC Traditions are questioned, that soon theirs will be also, since they come from the same roots and as 'inspired' traditions must logically be the same lest they are shown to not be. The reason they must reconcile, and cannot reconcile is because of these Traditions."
I think you misunderstand what we Latins and Orthodox are talking about when we speak of Holy Tradition. You referred to Papal Infallibility and purgatory as Traditions. They are not. As was pointed out, there is only one Holy Tradition; there are many traditions. Both of your citations are to dogmas of the Latin Church. These dogmas are, the Latins would say, in accord with Holy Tradition. We Orthodox say otherwise. How Holy Tradition plays itself out in dogma can be and sometimes is quite different between the Latin Church and Orthodoxy. Claims to base a dogma or a belief on Holy Tradition is no assurance that the "dogma" or belief or practice is not in fact heretical. There are many, many examples of this in the early One Church, especially in the East. As a general proposition, it was Rome which was the bastion and beacon of Orthodoxy for the first 800 years of The Church. Since then, on account of the influence of +Augustine and the gradual and increasing secular role the Pope played along with the influence of temporal rulers like Charlemange, Orthodoxy believes that Rome fell into error. of course, Rome believes otherwise. At any rate, individual hierarchs, groups of hierarchs, entire particular churches within The Church can and have misinterpret(ed) Holy Tradition and scripture or the decisions of Ecumenical Councils and fall into heresy. Only The Church can infallibly glean the Truth from scriptures and then through the use of Holy Tradition.
So what you are saying, if I may paraphrase, is the interpretation of the Holy Traditions are different, not the Traditions themselves.
