I am talking about the Orthodox Church... Haven't you heard of it? If you know your history you will see that it was the Roman Catholic Church, and not the Orthodox Church, that started to change and and things. The pope didn't have all power alone from the beginning. He was the first among equals, not the only one. Then suddenly he wanted to be the only one. And then the latins started to add things to the nicene creed(filioque) and other things, and there you go.
Now you speak of protestantism, I have no respect for protestantism. It is not christianity. Of course there are some christians within protestantism historically that I admire, but other than that, it is a serious distortion of everything that christianity stands for.
