Codified religious beliefs are fiction.
The things described in works like the Vedas, the Torah, and the Bible are stories. Some are, at times, historical fictions, although most are for the largest part purely fantastical, but they are not true records of any real events.
Most people can grasp this, at least at the literal, factual level. Apart from the genuinely delusional, most of us understand that there is no cosmic entity that exists and identifies itself as the God of Isaac and Abraham, and that personally delivered stone tablets to Moses on Mt. Sinai at a specific date in history. Likewise, no Indra ever killed Vritra and set rivers free thereby, and at no point did a divine father-god impregnate a Jewish woman named Mary, whose son died and then physically rose from his grave.
Those things never happened in any way more real or meaningful or verifiable than the defeat, in a magical world just beyond a London alleyway, of an evil wizard named Voldemort by the plucky schoolboy Harry Potter. All fall into the same category: fictitious, fantastical fables.
That being the case — and regardless of what feels comforting or empowering to believe on a personal level, in terms of factual truth that is the case — we need to recognize that religious ritual is functionally an expression of fandom, no different from the expressions of fans of other forms of fiction. If you’re really into the Torah, maybe you wear a tallit and cover your head; if you’re really into The Hunger Games, maybe you get a mockingjay tattoo and do that three-fingered salute thingie. It’s all the same.
Only of course it is not the same, culturally or legally. A faddish diet like veganism or paleo is just that — a fad — but a religious diet like keeping halal or kosher is something that public institutions are typically required to accommodate, and that private institutions will be criticized for failing to accommodate. A burqa or a turban may be worn to school (although there is at least debate over that, from time to time); a Spider-Man costume or a baseball cap most certainly may not.
It is considered rude to point out this inconsistency. The fact (and again, it is fact) that religious texts are not true records of any real events goes largely unspoken in modern life. This is a useful reminder that “rude” is usually whatever threatens to undermine the cultural capital of the people who have the most of it already. It is also something that needs to change.
To be clear, this is not a call for a ban on religious expression. People should believe whatever irrational things give them comfort, and practice those beliefs in whatever way they see fit, so long as it does not harm others. There’s nothing inherently wrong in covering your head and praying to God, any more than there is in donning a plush suit and claiming to have the spirit of a wolf. It’s easy to see how either or both could help a person through life, and neither should be prohibited — though by the same token, neither should be privileged.
But let’s stop pretending that one is spiritually superior to the other, or that the plush-suited furry is in any way less rational than the pious churchgoer who dresses up sharp on Sunday.
