I'm a Roman Catholic convert (born into protestantism, converted as a teenager) who is looking at Eastern Orthodoxy. I have a question about my own faith that I wanted to address to converts. In Roman Catholicism, I usually get caught up in following the rules (do this, don't do this, do this before this, etc). Catholicism seems to loan itself to that legalism in some ways - examination of consciences, lists of venial and mortal sins, canon law, canon lawyers, etc. This side of the religion can be good to have a clear-cut answer of what is moral and immoral (something which the thousands of protestant denominations can't agree on). On the other side of the coin, focusing on always following the law can cause you to forget who created it (something the Pharisees learned, and now I am as well).
I was wondering how Orthodoxy and Catholic converts to the east felt about this subject. Did you all have similar experiences? What is Orthodoxy's stance on sin, legalism, and the like?
