Peter Waldo

This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.

Peter Waldo, also called Valdes or Vaudes in medieval sources, was a wealthy Lyon merchant who around 1173 gave away his possessions and began preaching poverty and lay Bible reading in the vernacular, rather than in the Latin reserved for the clergy of his own time.

That preaching gathered followers who became known first as the Poor of Lyon, and later, after Waldo's own name, as Waldensians. The movement's central practices, voluntary poverty and lay people reading and preaching scripture directly in their own language, were unusual enough in twelfth century Lyon to draw notice well beyond the merchant class Waldo himself had left.

A single merchant's decision to give away his wealth produced, within his own lifetime, an organized lay preaching movement that named itself after him, a direct line from one man's personal renunciation to a religious movement that would go on to outlast him by more than eight centuries, surviving under the name Waldensians into the present day.

The Latinized forms of his own name, Valdes or Waldensis, appear in medieval sources before the English convention Peter Waldo became standard, and it is worth noting that the movement's name, Waldensians, derives from his own name rather than the other way around, a mark of how closely the tradition's early identity was tied to the specific man who had begun it in Lyon around 1173. His own death date is not firmly fixed in the surviving record, usually placed around 1205, more than three decades after the renunciation that started the movement bearing his name.

The lay preaching movement Peter Waldo began around 1173 was condemned for preaching without ecclesiastical authorization at the Third Lateran Council in 1179, a formal ruling against a practice, unauthorized lay preaching, rather than against Waldo's teaching of poverty itself.

That condemnation was followed by outright excommunication under Pope Lucius III by 1184, a rupture that pushed the Waldensian movement outside the institutional church for the next four centuries. Waldo's own death date is not firmly fixed in the surviving record, usually placed around 1205, so the movement continued underground for the great majority of that four century exile without its own founder still living to guide it.

The Waldensians survived that long exile and joined the Protestant Reformation in the sixteenth century once a wider movement existed outside Rome for them to align with. Their modern descendant united with Italian Methodism in 1975 to form the church this atlas holds today, so the 1179 and 1184 rulings against Waldo's own preaching mark the start of a separation the tradition did not formally resolve, by merging into a recognized Protestant body, for nearly eight hundred years.
