Definitely thought provoking. I would previously say I'm agnostic, as I don't rule out the idea of a higher power but don't see it within a Christian framework. But yeah, cultural concepts of Christianity are definitely embued here (UK) with holidays and ways of behaving. We probably don't even go as far as Americans to say happy holidays instead of Merry Christmas. I remember learning the Lord's Prayer at primary school and being strongly encouraged to pray in Friday assemblies.

At the same time Christianity in its overt forms was never that present in my direct family life. Neither of my parents were religious at all, I was probably in my early 20's when I went to a (Western) Christian service. I did get taken to an Orthodox service when I was 8 or so because that was nomally what my granpa was, but it was all in Serbian and I had no clue what was going on.
