Gotta have faith?

This recent article about how a growing number of Americans have changed their religious affiliation since childhood got me thinking about the role of faith in how we raise our kids.

Do you think children need a religious/spiritual foundation in order to learn about morality and how to treat others in the world? Is it important that we regularly bring our children to mosque/synagogue/church or some other gathering where people promote respect, kindness and ethical behavior?

And what do you do if you and your spouse come from different denominations or faith backgrounds?
