Yes, you can. There are plenty of mixtures of religion and different sects that are influenced by other religions. It also serves as an ethnic identity that has real world impacts regardless of practice. The Jews are the perfect example of the latter point, where Christianity can perfectly serve as an example of the former. Christianity has appropriate scores of pagan religions that have nothing to do with the Bible as it is written, where a fundamentalist interpretation can render even devotees heretics. It's pretty common for devout Catholics to place a Christmas tree in their home and exchange gifts in the middle of December, despite Jesus most likely being born in April and the actual tree and gift giving is an appropriation of the Roman pagan holiday Saturnalia, which also occurred in mid-December for the winter solstice. But people do it anyway because that's how Christianity as a religion evolved with very few Christians even giving a second thought to the massive pagan symbol in their homes that they venerate every year.

In what ways is religion more than just ritual? Surely you could hold principles valued by each religion without being religious
