What was the church in the wilderness called?

The church in the wilderness is often referred to as the "Waldensians." This movement began in the late 12th century in the region of the Alps, led by Peter Waldo, who advocated for a return to the teachings of The Bible and emphasized simplicity, poverty, and preaching. The Waldensians faced persecution from the Catholic Church for their beliefs and practices, which they felt aligned more closely with early Christianity. Their legacy continues today, with a significant presence in parts of Italy and other regions.
