As a nonreligious person, where do you get your moral guidance?

[arewethereyet]

The belief in transubstantiation, a religious belief, is not necessarily a moral belief.

Of course it's a moral belief, Catholics believe they are doing something moral by drinking the blood and eating the body of Christ. A cannibal's morality, if you will.

 
Look up transubstantiation.  It's the belief that the Eucharist and the wine are actually transformed into the body and blood of Christ.  It's not a moral issue.
