This is an interesting Kickstarter project. Chrystine Trooien is trying to provide a resource for secular parents to teach their children about Christianity in a way that both brings alive the myths and contextualizes them as myths. The project reminds me of Richard Dawkins’s The Magic of Reality: How We Know What’s Really True which teaches children about mythological approaches to nature next to properly distinguished scientific understandings of nature. This book looks to focus in more specifically on Christianity and to be organized around Christian stories and concepts.
