There is, however, a tendency to use it above all to refer to the Protestant Reformation in the sixteenth century. This article analyzes the idea of reform found in the writings of the Protestant reformers, considering both the background of the medieval terminology of reform and the contrast between the idea of reform and the idea of restitution held by the radical reformers.esProtestantismHumanitiesTerminologyRestitutionPhilosophyArtPolitical sciencearticle
