The Waldensians: Origins (Chiesa Evangelica Valdese)

This is not a medieval source. It is cited as the statement of the church that descends from the movement, to set beside medieval accounts written by its opponents. It presents Waldo as a merchant of Lyon who sold his goods for the poor and had parts of Scripture translated, and says that he and his companions preached without intending to found a new church.

For the events of the twelfth century it has no independent authority; for how Waldensians understand their own beginnings it is the primary document.
