I think that your perspective may be reflecting an idealisation of how The Orthodox Churches function. If you look at Russia now and if you look at Ukraine now, if you look at Turkey and The Orthodox Church there and if you look at Greece, and in The United States, the ideal you present isn't quite how things work today. I do not mean to disparage any of The Orthodox Christians that I know here, nor to say things about their churches that I'm not qualified to say. Nevertheless, there is a degree of stamping out happening in Russia, there is a degree of stamping out happening in Ukraine. So, even though they are extreme examples, the practise of stamping out is not unique to mediaeval Western Catholicism.
I believe then unless we abandoned the idealisations and the pretended rightness of this or that church, including the Catholic Church there is no way ahead for ecumenical discussion. And by we, I mean participants in Christian Forums.
I also believe that history as valuable as it is and from which many lessons may be learned, will not help us in our current divisions, within Christian forums.
I do admit, there is a certain pleasure to playing the game the way it is played here. We each get to pick the history we like most, we each get to quote the Saints we most admire, we each get to pick on the alleged faults of the other churches as we please, or at least to point them out. It makes for lively debates and discussions. Tally-ho and all that ...
By the way, I wrote this at about 2:30 in the morning, so please make allowances for that.
