I may be wrong, Jack, but I think you're wrong.
I have been at a struggle between east and west for some time now. And though I remain Roman Catholic, and have a great love for the east, and contemplate a conversion to Eastern Orthodoxy every day.
Through my study, and prayer, I have found profound theological differences between Orthodoxy and Catholicism, most of which have already been mentioned in this thread.
Catholicism and Orthodoxy are both Christian faiths, but they aren't the same faith, this is obvious to anyone who truly goes beyond the facade of the ecumenical movement and truly studies the rich litrugical and theological traditions of both east and west.
The Patriarch of Mosocow, in my humble opinion, does see the profound differences between Catholicism and Orthodoxy, and is upset about the proselytizing of the Roman Catholic faith, because he believes Orthodoxy to be the one true Church.
I don't see how any educated Christian can believe that two Churches, or three, or four, or however many, are all apart of the same Catholic and Apostolic Church. There is only ONE true Catholic and Apostolic Church, and considering the profound theological differences between Catholicism and Orthodoxy I do not see how both make up this one true Church.
"Those who attack the Church of Christ by teaching that Christ's Church is divided into so-called "branches" which differ in doctrine and way of life, or that the Church does not exist visibly, but will be formed in the future when all "branches" or sects or denominations, and even religions will be united into one body; and who do not distinguish the priesthood and mysteries of the Church from those of the heretics, but say that the baptism and eucharist of heretics is effectual for salvation; therefore, to those who knowingly have communion with these aforementioned heretics or who advocate, disseminate, or defend their new heresy of Ecumenism under the pretext of brotherly love or the supposed unification of separated Christians, Anathema!"
-Saint Philaret the Confessor
