There is a difference between being an observant Christian and the way one was brought up. I was baptised and brought up a Catholic but have now ceased to believe in God but I remain a Catholic by my culture and nothing will take that away
From somewhere in The Guardian.
I rather think this happens to a lot of people. Not just Catholics. The culture, the manner in which one thinks about a point or a problem, will persist long after the initial reason for that culture existing does.
Certainly has happened to me. I’m identifiably Catholic in the way that I structure certain moral arguments for example. Don’t always come up with the same results, but the structure, the method of approach, is much the same.
