Cathari [Gr.,=pure], name for members of the widespread dualistic religious movement of the Middle Ages. Carried from the Balkans to Western Europe, Catharism flourished in the 12th and 13th cent. as far north as England. It was known by various names and in various forms (see Bogomils; Albigenses). Catharism was descended from Gnosticism and Manichaeism and echoed many of the ideas of Marcion. The Cathari tended to reject not only the outward symbols of the Christian church, such as the sacraments and the hierarchy, but also the basic relationship between God and humanity as taught by orthodox Christianity. Instead, the Cathari believed in a dualistic universe, in which the God of the New Testament, who reigned over spiritual things, was in conflict with the evil god (or Satan), who ruled over matter. Asceticism, absolute surrender of the flesh to the spirit, was to be cultivated as the means to perfection. There were two classes of the Cathari, the believers and the Perfect. The believers passed to the ranks of the Perfect on acceptance of the consolamentum, a sort of sacrament that was a laying on of hands. The Catharist concept of Jesus resembled modalistic monarchianism in the West and adoptionism in the East. Persecution, such as that by the Inquisition, and the efforts of popes like Innocent III destroyed Catharism by the 15th cent.

or Albigensians

Heretical Christian sect that flourished in Western Europe in the 12th–13th century. The Cathari adhered to the dualist belief that the material world is evil and that humans must renounce the world to free their spirits, which are good and long for communion with God. Jesus was seen as an angel whose human suffering and death were an illusion. Followers divided themselves into the “perfect,” who had to maintain the highest moral standards, and ordinary “believers,” of whom less was expected. By 1200 they had established 11 bishoprics in France and Italy. In an effort to stamp out their heresy, Pope Innocent III declared the Albigensian Crusade, in which the populace in Cathar regions was indiscriminately massacred. Persecution through the Inquisition, sanctioned by St. Louis IX, was even more effective, and when the Cathar stronghold of Montségur fell in 1244, most Cathari fled to Italy. The movement disappeared in the 15th century.
