Italian Catharism entered the thirteenth century as a fractured church, with Concorezzo and Desenzano being respectively the bastions of the moderate and absolute schools. The ordo of other churches, such as those at Florence and the Val del Spoleto, remains unknown. Like the Languedoc, the political situation helped nurture the growth of Catharism, but, unlike the south of France, opposition did not generally come from Crusaders but from reforming movements that originated both within and without the Church. From within, the way was led by St Francis of Assisi who, while not mentioning the Cathars — or Patarenes as they were frequently known in Italy — by name, stressed the importance of closely examining the beliefs of potential new recruits to the Franciscan order. He wrote of the importance of regular attendance at both church and confession, and of the need to respect priests. He also stressed the physical reality of Christ’s birth, which went against the Docetism of the Cathars.
There were also popular preachers such as John of Vicenza, who commanded the attention of huge crowds
Every time they gave a sermon. In John’s case, it led to the rise of the Alleluia movement, a popular, if short-lived, phenomenon in the tradition of the pro-reform Pataria of Gregory Vll’s day, and John presided over the mass burning of 200 heretics — mainly Cathars and Waldensians — in Verona in August 1233. John’s success led to the founding of a number of lay confraternities, such as that of St Maria of Misericord in Bergamo, which were intended for people who wanted to further their spiritual practice without having to become a monk or nun. Its members swore to adhere to certain rules, such as the refusal to shed blood, to bear weapons and to refrain from an unethical way of life. They also actively worked towards the repression of heresy.
While the various movements acted as outlets for people who were dissatisfied with traditional forms of religiosity, conflict between the papacy and the empire created space in which Catharism could flourish. The reign of Emperor Frederick II (1220—50) saw these confrontations reach their zenith, and Italian politics came to be dominated by two factions, the pro-papal Guelphs, and the pro-imperial Ghibellines. Frederick did little to encourage the persecution of heretics, and the papacy, keen to gain allies in the key cities of Lombardy, did not press the heresy issue. Also, many cities, wishing to maintain their independence, did not enforce anti-heresy legislation, not because they were especially sympathetic to groups such as the Cathars or the Waldensians, but because any attempt to persecute heretics would have necessarily led to a greater role for the Church, thereby decreasing the cities’ autonomy. Cathars were relatively free to go about their business under the protection of the Ghibelline nobility, and in Lombardy, a Languedocian Cathar church in exile flourished.
