I like to keep things simple. In my terms of reference, be they right or wrong, religion is about a belief in a God. While spirituality is about a belief in the existence of the spirit, soul or whatever you like to call it, independent of the body.
Nothing I've read or heard has induced me to believe the two are dependent on each other. I've known a few religious folk who are not spiritual, and I've known a lot of spiritual people who aren't religious.
If others wish to combine the two, fine - just don't try selling the concept to me. I've got as much use for it as the headless horseman has for a hat.
