Many years ago I was interested in expanding upon the Church of Stellar Divinity [http://wiki.travellerrpg.com/Church_of_the_Stellar_Divinity] as a sort of Catholic church for the Imperium, but I never did more with it that speculate that:

1) Jump space was the CoSD's vision of Hell, since a person therein was totally separated from his or her stellar diety and

2) This meant that most starships included a small CoSD shrine wherein the souls of those who died while in jumpspace could be held until the ship re-emerged into normal space.
