Trouble with three religions

Through many of the chapters pi has been struggling with his religious beliefs. First there was a feud between his three religious leaders, each one declaring that he follows a different religions. Not much is solved and for the most part the matter is left alone. But after that he starts getting angry with those who do not follow or worship god. Then many temples, mosques, and churches ban him for his three religions and make him find god on his own. Which brings up the question does it matter how you find or worship god or is it that you just do it anyway you can?
