Very good point about Zhaan, and you're right. I guess I had been reading so much in this thread about Trek and allusions to Judeo Christianity, that my mind was clouded from seeing the Delvians' more "Earth/Mother/Goddess' type of faith. Thanks for that reminder.
Oh, and almost forgot, also on Farscape, Stark. The former Bannek Slave was also a deeply spiritual being, pretty much had no choice in the matter, as his person was by it's composition more in tune with his mystical side than most beings. It was almost a curse for him in some ways, but he took his role and the help he could offer others seriously.
As for B5's treatment, being a person of faith myself that was one reason why I've enjoyed the show so much. For my part, I appreciated what appeared to be an even-handed approach, taking in both the negative and the positive. Many times, I've relayed how ironically I almost swore off the series after watching the episode "Believers".
Wow, that would have been a mistake.

IMO, as far as televised science fiction goes, B5 has had the best handling of the topic. Absolutely incredible.
In nuWho, one of my most favorite episodes from the first two series was "The Impossible Planet / The Satan Pit".
That was a great one. And it was one of those occasions where the Doctor had to just shrug his shoulders and say, "I got nuthin', just trying to deal".
