Good point. I bassically only read Ender – so I’m not familiar with his other books.

I read some of his essays and interviews, and he is very outspoken about his religious convictions and beliefs. He likes to moralize alot to the point of almost being scary sometimes.

But I’m sure there many authors out there who portray religion in positive way.

Might be true in general, I don’t really know, but, I thought of a prime example of religion being portrayed positively in science fiction: Orson Scott Card, one of the biggest sci-fi novelists around, has a lot of religion in his books portrayed in good light.
