France gathers three cities where the shape of Latin Christian doctrine, dissent and learning was argued out and, in two cases, formally settled.
Paris carries the medieval church's intellectual weight: the cathedral school that became the University of Paris made the city the center of scholastic theology, where Peter Lombard, Albertus Magnus and Thomas Aquinas taught or studied, and Notre Dame and the Sainte Chapelle, built by Louis IX to house relics of the Passion, are its two great statements in stone. The French wars of religion left their mark here too, most sharply in the Saint Bartholomew's Day massacre of 1572, and the 1789 revolution made the city the testing ground for the secular settlement French law still calls laicite.
Lyon, the Roman Lugdunum and capital of the Three Gauls, saw its Christian community produce the martyrs of 177 described in a letter Eusebius preserved, and its bishop Irenaeus wrote there; its archbishop still carries the title Primate of the Gauls. Two ecumenical councils met at Lyon, in 1245 and 1274, and the movement that became the Waldensians began there in the 1170s when a merchant named Valdes gave away his property and had the gospels translated into local speech.
Orange, the Roman colony of Arausio in Provence, hosted a council in 529 under Caesarius of Arles that closed the long argument over grace following Augustine, ruling that even the first stirring of faith is a gift rather than human initiative while refusing to teach that anyone is predestined to evil; its canons, confirmed at Rome in 531, are still quoted in Catholic and Reformed argument alike.
Between a university, two councils and a third settling a doctrine still cited today, the group shows France as a place where Christianity kept having to explain itself.
