Joan was used.  The RCC couldn't imagine an uppity woman and canonizing (not cannonizing) her for nationalist purposes,  an order of nuns, the Jeanne D'Arcs were approved.
Their mission: domestics to clergy!
Also, there there are Jeanne d'Arc kidney beans, in her honor. Potent, as in powerful with a sword?
Didn't Jesus say those who take up the sword perish by it?
Evidently, Joan didn't read that scripture or rationalized it.
But those who support violence rationalize Joan's sword.
Alas! "And Jesus wept!"
