In the effort to offend none, the public schools have managed to offend practically everyone--either by leaving religion and ethics out of curricula altogether or by teaching them in a way that satisfies neither believers nor skeptics. In sympathy, we'll say that the public schools are in an impossible situation. They are legally bound to avoid the appearance of promoting one religion over another. And in a mixed classroom, how can you take one religion seriously without antagonizing those who don't share it? The inevitable result is summed up by a character in P. D. James's mystery Original Sin:Mrs. Bauer's comments are balanced and fair. She does not treat each and every faith as valid pathways to the same God. Neither does she promote neglecting (or avoiding altogether) teaching about other faiths. What she does affirm is that our children should know how to respond to those of differing faiths and convictions and how to address them with grace and humility. That cannot be done if we know little to nothing about other faiths and convictions.
"There were a dozen different religions among the children at Ancroft Comprehensive. We seemed always to be celebrating some kind of feast or ceremony. Usually it required making a noise and dressing up. The official line was that all religions were equally important. I must say that the result was to leave me with the conviction that they were equally unimportant."
When you're teaching your own child, you have two tasks with regard to religion: to teach your own convictions with honesty and diligence and to study the ways in which other faiths have changed the human landscape.
Also, she does not ignore the simple fact that people of faith have influenced history at every turn and to avoid the study of religion and ethics is catastrophic. Until a student is able to soberly and comprehensively address the influence various faiths have had on the history of humanity, his study will be woefully incomplete.
