Sith Emperor - Pope Benedict XVI
Admiral Piett - Fr. Rostand
Grand Moff Tarkin - Fr. Schmidberger
Obi-Wan Kenobi - Bishop Williamson (the jury is out)
Yoda - Bishop Williamson (the jury is out)
Luke Skywalker - (Many trads leading the Rebel Alliance)
- Alternate: Since the Force is strong with him, he represents Fr. Pfeiffer, Fr. Chazal, and the other clerics of the resistance.
Han Solo - CathInfo
Chewbacca - ???
Leia - ???
Jabba the Hutt - ???
Boba Fett - ???
I wouldn't normally identify CathInfo or myself with Han Solo (it's kind of like bragging, right?), but 1. he's a layman and 2. he lent his services -- a vehicle -- to important agents of the Rebellion: Luke, Obi-Wan, Leia, etc. so they could use their unique powers to get the job done.
Then again, the "Force" in Trad Wars could be interpreted as a combination of the State of Grace, clear reasoning/thinking, decent education on Catholicism and the Crisis, ability to write well and influence others.
The Dark Side would be twisting that training (understanding human nature, ability to write/speak convincingly, using the understanding of how Catholics think) and mixing it with anger/hatred/violence (modern political techniques, brainwashing, manipulating people's thinking, using sophisms and deception) to achieve "evil" ends.
The Good Side of the force uses clear reasoning; the Dark Side uses sophisms, straw man arguments, secrecy and evasion. Those are the seductive tools of the Dark Side that the "Good Side" can never use, no matter how desperate things get. That would be turning to the Dark Side.
Just like any trained Jedi Knight can become superficially more "powerful" by turning to the Dark Side, any priest can become more politically powerful by resorting to sophisms, straw man arguments, etc. -- abusing his training in Logic, etc. to manipulate people and achieve more power.
Spending time with Yoda or another Jedi master would be the equivalent of going to a (trad) Seminary for a time.
Speaking of Yoda, Bishop Williamson is more like Yoda in many ways. "For 800 years have I trained Jedi knights. My own counsel will I follow on who is to be trained." Bishop Williamson's career has mostly been as a professor -- training young men to become Jedi Knights (seminarians to become priests).
Of course, his appearance/bearing is more like Obi-Wan -- they even both have a British accent!
I don't know, though...Bishop Williamson is a bit eccentric like Yoda. Of course, BOTH stayed faithful to the end.
