Abstract: The article considers the preaching as a transmission of religious knowledge since the 1520s. The “espace romand”, as a land of refuge and cornerstone of the Reformation, contributed to the establishment of assemblies, and subsequently of churches with international reach. Models of evangelization were therefore developed, reflecting a transmission of practices in the pastoral setting of a community, in particular drawing on the experience of the Meaux circle and the Waldesians dissent.
