This isn't a question about like, family traditions. This is a question about religious traditions. Is it religiously, and/or morally ok for someone of one religion (specifically Christianity, but other religions too) to participate in another, and specifically another Religion's traditions? Like, say, a Catholic travelling in Japan washing his hands in a shrine before entering a Buddhist temple. Or a Buddhist partaking in Communion. Should that be allowed? or should you say "I'm sorry, but, I'm Catholic." or whatever, and not have to partake in Communion or wash your hands in front of the gods. Note: Please be courteous. This is not a place to say like, "But Christianity Stole from a bunch of other Religions!" or something like that. Nor is this a place to debate religion. I am simply asking a question that I would like to see answered.
