I have met antiCatholic Orthodox, but I don't think that I (or most Orthodox converts I know) are antiCatholic any more than you would consider yourself antiOrthodox.
AntiCatholic is a very loaded word. You need to use it with more and purpose.
AntiCatholic is a very loaded word and those of us who are not members of the RCC must always do our honest best to be fair to Catholicism in every possible way. Now the RCC prides itself in the line, "The Catholic Church - the same yesterday, today and forever". There is no doubt that there is much truth in that line. The RCC still contains the essence of Apostolic Christianity. However, what about the EO Church? Who deserves that tagline more, the RCC or the EO?
It would seem that the EO Church has changed even less in recent decades and centuries than the RCC. Here is just a small sample of the RCC changes: (1) Regarding fasting, the RCC has given up most of it's former fasting requirements, especially regarding the meatless Friday rule, with the exception of Fridays in Lent. Now while it is true that fasting requirements were never core issues of the faith and simply Church rules, this still begs the question, how could eating meat on Friday for about 1,000 years prior to Vatican II be a mortal sin and then suddenly after Vatican II it is no longer a mortal sin? (2) The understanding of the sanctity of Catholic cemeteries has really changed. Formerly, unbaptized babies and suicide victims could not be buried in hallowed ground. This is no longer the case. (3) The use of Latin in the Mass was given up in favor of the use of the common tongue, though it has now been reinstated, but certainly on a small level. (4) I am sure that most non-Catholic observers who research the subject, are of the view that the RCC
has fundamentally changed it's teachings
re: religious liberty and the possibility of salvation for non-Catholics, just like Ultra Traditonal Catholics believe, especially concerning EO schismatics and Protestant heretics. Most of this change happened at the Vatican II Council. Don't get me wrong, I am most pleased that the RCC has changed it's teachings on said subjects. (5) There would appear to be at least four core RCC dogmas that have been infallibly defined in recent centuries, that were not included by the Council of Nicea. The 1st Vatican Council defined the Infalliblity of the Pope. The Council of Trent definfed Purgatory. Infallible Papal Decrees issued in 1854 and 1950 respectively defined the Immaculate Conception and the Assumption of the Blessed Virgin. Now there is no doubt that there is at least some foundation for all four of these teachings in Early Church history, depending upon one's point of view. However, it is certainly true that the Bishops assembled at Nicea did not consider any of these four teachings to be essential to the Christian faith. It is especially noteworthy that St. Thomas Aquinas, the most famous RCC theologian of all, did not personally believe in the Immaculate Conception dogma. Hence, we can see that it was still not a universally held view in the RCC in the 1200's, the century when Aquinas lived. (Yes, I am somewhat familiar with the "development of doctrine" thesis, but I will leave it to others to try and explain.)
To be fair, I have less knowledge of EO changes than that of the RCC, but that is not my fault as much as it is that the RCC changes are more readily recognizable by it's Papal decrees and recent Vatican Councils. Maybe some of our EO or RCC posters can highlight some of the EO changes? I do believe that the EO "commonly understood" view of salvation is not as strict as it was, but I do not believe that there has been any official change in the EO salvation teaching. Anyway, it appears to me that the famous RCC line "the same yesterday, today and forever" should perhaps be handed over to the EO Church, because it really does appear like the EO Church has changed less than the RCC, especially in key areas of faith and dogma? Maybe the Christian Forums line, "The Ancient Way", is rather appropriate to the EO faith?
