Yes, it's possible and I for one am an example. Technically, I'm Roman Catholic. I went to a Roman Catholic school, from its preparatory branch till the University. I was very interested in history and it led me to drift away from the Roman Catholic belief. I made my own interpretations and decided to go with my own beliefs. I guess you could say I'm a freethinker towards religion. I do not subject myself to religious gatherings anymore. I pray to God and the time and place does not matter to me, as long as I pray at my utmost sincerity.

I've had some friendly arguments with some of my peers who are part of another branch of Christianity. I shared my views and their response always starts with, "Because, in the bible..." I challenged their use of the bible and simply put, they said that if you're gonna part of a religion, you have to adhere to their teachings. In my view, that's just taking away free will. But hey, that's just me.
