So tomorrow is Sunday, and I want to attend a church. Problem is I can't choose which one.

You see, in my country majority of christians are orthodox christians, so that may mean I should join them. On the other hand, I'm still interested in catholicism and teachings of catholic church fathers. I attended my local catholic church last year during my first attempt to become a practicing christian.
I understand that I sound like a pretentious bean, but somehow the issue of choosing the right church is still bugs me. Thus I really need help of christians
