One of the often missed features of religions is that of cultural critic and cultivator. A group of people who find works of art that at least don't offend their sensibilities and which align with their didactic goals (child rearing, conversion, etc...) Having an explicit standard for judging art gives a means of determining what is that thick and thin: which pieces of entertainment are just that and which are meant to be shared, reenjoyed, and such.

Not endorsing a specific religion or philosophy here, but how is one to aspire to something more meaningful and deeper when they cannot even distinguish what that is?
