Everyone has talked about character roles in a future Trek production. What about a shipboard chaplain?
Virtually all U.S. Navy ships of any size have either a full time chaplain (or several of them) or on small ships a layperson spiritual adviser trained in handling the spiritual needs of the crew.
And for those of you who would maintain that this would not fit with Treks liberal worldview, I would like to refer to MASH.
MASH was a classic tv show and the liberalism of the shows producers and most of the cast was well known.
Yet almost from the beginning it featured the character of Father Mulcahy who was portrayed almost always in a good and favorable light.
