If I might be so bold as to speak for him, I don’t believe that Dr. Roman was saying that the Catholic Church should compromise on dogma, he was saying that there are perhaps no dogmatic differences on which to compromise. From the study that I have done, the only significant dogmatic difference is the understanding of the primacy of the Pope. The other differences that are usually cited are misunderstandings based on different languages and theological traditions. One example of this is the “filioque” clause that was inserted into the Nicene Creed by the west. For a long time I believed this was a significant dogmatic difference, and indeed Orthodox often argue that it is, but after studying the issue and reading what Catholics really believe about it (particularly in a treatise written by Pope John Paul II), I realized that I misinterpreted their understanding, and that the Catholic and Orthodox doctrines are mutually compatible. I believe this is also the case with other supposed differences such as the Immaculate Conception, Purgatory, Created Grace, and other teachings. You have to realize that a difference in “emphasis and expression” as Fr. Thomas J. Loya says, is not necessarily a difference in dogma. Regarding the Pope, Dr. Roman’s point is that since we were united as one Church for over 1000 years, there is reason to be hopeful that we can reach an agreement on this dogma once again as well. Most Catholics who have studied the issue will admit that the power of the Papacy has increased over time, particularly after the schism, and that it could be reassessed in a future Catholic/Orthodox council. Most Orthodox likewise will admit that the Pope was the principal bishop of the Church and enjoyed a primacy, though they debate what power this primacy entailed. Both will admit that the Church is infallible, and that this infallibility is expressed in ecumenical councils, with Catholics also extending the exercise of infallibility to the Pope when he speaks as head of the Church. The difference then is not as great as it might first appear, and I agree with Dr. Roman that there is hope for reconciliation. I would also like to caution against the term “true” church when used to compare the Catholic and Orthodox Churches. The Catholic Church has stated that the Orthodox Church is a true church, with valid orders and sacraments, and is a “sister” church, and the “second lung” of the Church. If we follow the logic of only the Catholic Church being “true” Church, then does that make the Orthodox Church “false”, fake, counterfeit, not what the Catholic Church has described her as? This term, while you might believe it to be correct, is however not helpful. You might think for example that someone’s haircut is silly, but you need not tell them that either. Both of us must abandon the triumphalist mentality that only exaserbates the schism and does nothing to heal it.
