Honestly? No. Religion, unless as part of a religious course, shouldn't have a place in curriculums. That's the only way to maintain neutrality. Now, an argument to this may be; why's athiesm the default? And that's simply because athiesm is less varied than religion. You cannot possibly factor in every religious explanation, and if you didn't, then you're exclusionary (Honestly, it's also that athiestic explanations better reflect academic teaching.)
That's not to mention the whole imposing-your-faith thing. You got to be respectful towards students' freedom of belief. And that still applies in schools with less varied student bodies, where some sort of religion is majoritative. You never know who's in the closet.
