 This article takes up the question of how the Poor Waldensians of Lyon, a predecessor of the medieval Franciscan movement, managed to become one of the main Reformed ecclesiastical bodies starting from the sixteenth century. The Italian Waldensians are an interesting ecclesiological case since during the time of the Protestant Reformation they underwent a significant transformation, from a nomadic and sectarian heterodox group to an ordered Reformed church body inserted within the broader international network of Reformed churches. This meant their survival through the support of Protestant diplomacy and public opinion, opening a door for Protestantism in the stronghold of Roman Catholicism. Their ideological move was not without changes on many ecclesiological points (Scriptures, sacraments, justification, etc.), in addition to the abandonment of their former pauperistic roots. The study shows how struggling religious minorities can at times undergo essential changes in order to guarantee their survival.
