It gets a bit confusing when it comes to Christianity and all the billion denominations there seems to be :lol:
True Christianity is non-denominational - it's about a personal relationship with God through Jesus Christ. Just because you are catholic, protestant, baptist, lutheran, episcopalian or whatever else is out there it doesn't mean you are a Christian. It just means you belong to a particular variation of the religion, not necessarily a participator of the faith itself. Anyone can go to church each Sunday, say some prayers, wear a cross around their neck, read the Bible and preach the Gospel - it does not make them a Christian. To become a Christian is a choice, it cannot be made for you by anyone else - I've been to mosques, but I'm not Muslim. I've attended Hindu temples but I am not a Hindu. Similarly, belonging to a denomination does not make you Christian.
God can turn up anywhere - catholic church, protestant church, middle of a field, when you're having a bath - He's not fussy about where. He's not interested so much in the geography, liturgy, whether you have a rosary, whether you confessed enough to a priest in the next box - His interest is in people. I've met catholics who are more passionate about God than others claiming to be pentecostal - no one has the monopoly on His power as He'll turn up wherever the need is. The problem with religion is it's full of rules and laws - the freedom comes in the faith, not the following of rules to the letter. Many denominations focus on getting it right when faith calls for you to step out on a limb at the risk of being called a fool and seeing what happens when you do - in essence, Catholicism focusses largely on rules and regulations (this is a broad assessment) and less on the power of God and forging a close relationship with Him which leads many to believe that all Catholics regard God as just the guy who comes down on you like a ton of bricks if you don't do as you are told.
(by the way, this was not part of the debate about God's existence - just a clarification thing)
