I wasn't raised in any religious tradition (except insofar as you could consider my parents' committed atheism a "religious" position). I don't really believe in god but I don't believe in no-god. it's just never been part of my life. But I am really isolated and missing a sense of community. I also struggle a lot with depression and I've considered "finding religion" but I don't really know where you start with that. forgive me if this is a weird question. just something on my mind right now.
edit: i'm not asking abt any specific religious tradition. I live in a big american city so i'd probably have a variety of options but it seems to me that the most likely places would be churches of any denomination or a mosque.
You don't have to be a baptized Catholic. The Catholic church considers any baptism performed in the name of the father, the son and the holy spirit and involving contact with water as valid. This includes most other Christian denominations, including orthodox Christians, Anglicans, Lutherans and Baptists.
