Thompson says that heresy could be defined “only with
reference to orthodoxy” (p. 125). So, the church first defined a definition of
the theology or a belief, establishing its limits and boundaries. So, when
someone or a group, leave these boundaries and go farther from them, they were
considered dissentients, “and liable to ecclesiastic sanctions if they did not
conform” (ibid).
Early and Medieval church were focused in the teaching and
Christian praxis, very orthodoxy all the time. It doesn’t mean that never had
heresy’s problems, because that did it. When lays began to be involved in the
life of the church the heresy started, “this may be connected with an
increasing level of a lay religion, and the willingness of participants to try
to clarify what they personally believed” (Thompson, p. 78). Around 1000,
Leutard was accused of denying the obligation to pay tithes. Around 1025,
emerged an Italian group who believed they don’t need the church and had any
ideas similar to the Cathars. In the
twelfth century, the church gave a powerful response to the existence of heresy
from the church authorities. The First and Second Lateran Councils talked about
heresy. “The Cathars were anathematized in 1179 at the Third Lateran Council”
(Thompson, p. 126). “The lay powers were joined to support the church, and the
ecclesiastical authorities were empowered to investigate suspect heretical
meetings” (ibid). By 1215, the Fourth Lateran Council decreed directed against
Catharism. “The decrees also renewed the command to hand heretics over to the
lay power for punishment… is demonstrated by the fact that indulgences granted
to Crusaders were extended to those who fought against heresy” (ibid). So we can see the development and involvement
of church against heresy
In that century highlight two heretical movements:
Waldensians and Cathars. Waldensians a
group created by Valdes of Lyon, after his conversion. He abandoned his fortune
and pursued a life of poverty. More people added to him and began to preach the
gospel and Jesus’s life. Many people were attracted for them and authorities
were worried for their impact. They didn’t want to separate from the Catholic
Church. They simply wanted to live as whole-hearted followers of Jesus. But the
challenge of their simple lifestyle, the popularity of this new movement and
their preaching, without the authorization of the Church, it brought them
problems and opposition, and they were excommunicated. “Valdes himself was
essentially moderate, and may well have hoped reconciliation with the church,
but more radical groups appeared elsewhere… insisting they were sole path to
salvation” (Thompson, p. 128).
