At merely 17 years the same age as many of today's high schoolers Joan of Arc became the supreme general of what was left of the beleaguered French army. She then led the spectacular military campaign that broke England's back in the One Hundred Years War, and which ultimately allowed France to reclaim its independence.
Upon her capture a few months later, she was turned over to an ecclesiastical court. There she was charged with dozens of crimes against her God and church, including idolatry, sorcery, witchcraft, apostasy and heresy. After six rigged trials oozing of treachery, that day's religious mafia could not get a charge to stick. Not a single one.
So what was it that finally provided grounds for the bishops to burn alive the heroic and courageous Maid of Orléans in her own beloved homeland? Answer: Not dressing as becomes a modest female parishioner.
