Does it Matter?

Q: Does it matter or not whether or not a religion is true? What does it mean to say that a religion is “true?” Can a religion function as religions do whether or not they are true?

A: I think it's very important that a religion's adherents find some kernel of truth among its tenets. Though many if not most of the stories and rituals associated with a certain religion may be viewed simply in terms of elaborate metaphor, the underlying root of the faith must be grounded in something to which worshippers can identify, whether it is the natural world of native religions, the monarch-like gods and goddesses of classical faiths or the "golden rule" of brotherly love and a superior being that forms the basis of so many transcendental beliefs. While outsiders may debate the 'truth' of one specific religion or another, it's imperative, I think, that those who actually practice the religion find something within it that speaks of the supernatural plane, or they wouldn't continue to adhere to it and the faith would cease to function.

Q: But isnt it is possible for parctitioners to believe it true without it being true? And if so will religion ufcntion for them in the same way whether or not it is true?

A: Message: If we're defining Truth in the scientific sense - that is, that which can be proved by applying scientific method to hard evidence - then I suppose that it's certainly possible for a congregation's beliefs to be totally off the mark, and that they could continue to hold these beliefs indefinitely, regardless of the facts weighed against them.
I guess I was looking at truth more as a subjective notion. ;)
