Agreed with Ancient Mariner, in that the episode didn't bash religion, it bashed the small minded thinking that oppressed science in the name of dogma. As mentioned, Bruno was a devoutly religious man, who merely stated that an infinite creator could surely create an infinite creation. For that, he was murdered, as were many others during the Inquisition. My mom is very devoutly Christian, and she didn't feel that the show bashed religion at all. To her, the show seemed to say that people can be faithful, and still accept the tenets of scientific thought.
