Our three kids were raised in the Lutheran and Presbyterian faiths, even attending the Lutheran grade school during their younger years. They were required to memorize Bible verses and had religion classes where they learned the fables about Noah’s Ark, The Plagues, parting of the Red Sea and the Exodus, etc. Even though we were involved in church and took our kids regularily, there were certain things we didn’t take literally. We allowed our kids the freedom to discuss their questions, doubts and opinions openly and honestly with us and encouraged them to ask their teachers and pastors their opinions. We also always told our kids that a teacher doesn’t know everything, and a pastor doesn’t know everything and much of what they say is THEIR OPINION and they could be wrong. It was through this freedom that they eventually came to their own conclusions about religion and god as they got into their teens.
All of us are now atheists and our kids (now in their 20s) probably know more about the Bible than most Xian adults. One cannot debate and argue what they do not know. We have always taught our kids to investigate BOTH sides of an issue in order to have intelligent and fair discourse on any subject. If you don’t know the other side, go find out before engaging in debate or criticizing something.
