Catholic, Critique, Heresy, and Response
Published by Mitch Williamson under History on 8:52 PMPelagius
The history of medieval Catholicism was one of consistently struggling to get a uniformity of belief in the face of constant questioning. Once Christianity became linked with the Roman power structure, differences of opinion about religious matters became “heresies,” equivalent to treason. In the early centuries, differences were resolved in church councils that established correct belief, and later in the West, popes in consultation with bishops determined what was orthodox and what was heretical. Nevertheless, throughout this age of faith church leaders had to wrestle with confronting and suppressing heresies.
Before the twelfth century, heresies grew from a variety of opinions—many left over from earlier deep discussions about the nature of Christ, humanity, and the clergy. The Eastern Church had always had a tradition of actively discussing theological issues, and three important heresies arose there in the early Middle Ages. In the fifth century, discussions about the nature of Christ led to two different opinions: The Nestorians emphasized the split between Jesus’s humanity and divinity, claiming that Mary was the bearer of the human person, but not of God. In response, others emphasized Jesus’s divinity, claiming that the divine portion of God obliterated the human at the Incarnation much like the sea would overwhelm a drop of honey. These were called “Monophysites” (“one nature”). The Council of Chalcedon in 451 condemned both positions arguing that Christ was fully human and fully divine. However, Nestorians and Monophysites continued to flourish in Egypt, Armenia, and even as far away as China.
In the eighth century another serious conflict arose in the Eastern Church that further emphasized the differences between East and West. The Byzantine emperor Leo III (r. 717–741) ordered all icons destroyed to avoid idolatry, and in an autocratic style, he intended for this decree to apply to all Christendom, East and West. This introduced iconoclasm, which raged in the East for a century, during which many mosaics in Constantinople and Asia Minor were destroyed. Ultimately, the iconoclasts were discredited, and icons remained a part of Christian worship.
In the West, the church father, Augustine, spent much of his career battling three heresies. The Manichaeans believed that a good God could not have created evil, so they posited the existence of two gods, one good and one evil engaged in a timeless battle for the soul of humanity. This dualist belief reappeared in the Albigensian heresy that flourished in southern France in the twelfth century.
Augustine also battled against Donatism, which split the North African church for centuries. The Donatists argued that priests who had turned over sacred books during the Roman persecutions should lose their offices. Augustine and the orthodox position was that sins of a priest did not affect the efficacy of the sacraments they perform. The violent proponents of both these positions did not end until North Africa was conquered first by the Vandals then the Muslims.
Augustine’s last struggle against heresy took a more intellectual turn when he penned his arguments against the Pelagians. Pelagius was a British monk who argued that free will was possible, that people could choose not to sin. Augustine, drawing from his own struggles against lust and sin, denied this possibility and claimed that people were burdened by original sin. Augustine’s position became the orthodox one, and Pelagianism was condemned.
By the twelfth century in the West the greatest critique of the church came from those who believed that the church had become corrupted by wealth. There were many groups who advocated following what they called the “apostolic life,” a simple existence embracing poverty, reading the Bible, and preaching God’s word. The most famous of these groups was the Waldensians, who were centered in southern France. Their leader, Valdes of Lyons (also known as Peter Waldo) was condemned as a heretic in 1181, but the movement continued in spite of repression. There are even some Waldensian churches today.
Late in the Middle Ages, other critics challenged the hierarchy in ways that foreshadowed the sixteenth-century Reformation. John Wycliffe in England and John Hus, in what is now the Czech Republic, were influential at universities and questioned papal supremacy and other church doctrines.
In the thirteenth century, the established church felt sufficiently threatened by these various heresies to establish a new court to discover and root out heretical ideas. This court was the Inquisition, and it was different from the many criminal courts in the lands because it was concerned with ideas instead of actions. Consequently, it had to resort to torture to find out what the accused was thinking, instead of other evidence to determine what he or she had done. The progress of the Inquisition contributed to the breakdown of the medieval religious structure.
