While there’s plenty of literature out there for the mainstream religions, and a growing number of books on paganism and earth-based spirituality, it can be difficult to find some non-Christian lit for young ones. I had several youth Bibles growing up (my dad was religious, my mother sort of agnostic), and given that the religion is centered around the book I think it’s to be expected that it would be so readily-available.
But if you want to introduce your children to goddess-centered religion or other forms of paganism, you pretty much have to rely on what you’ve learned yourself. That’s okay; in fact, it makes it more personal, and parents who take an active role in teaching their children rock! After all, parents are their children’s first teachers, right?
