On a very high level it does look like there is no difference between Roman Catholicism and Orthodoxy. But is our faith merely a high level view and each Church through their own traditions can simply make stuff up in the details? The more I learn of Orthodoxy, the more foreign it to Roman Catholicism, at least in my view. Externally and mechanically there if very little difference. But when we look at what all of these means and what we actually believe about each and every single thing in our faith, we are so far apart.
I'm not trying to promote division here. Just being honest about how things are and what things are.
