This critical edition of the Registers of the Consistory of Geneva in the time of Calvin reveals what life was like during the Protestant Reformation in a city where ecclesiastical discipline affected many. These valuable primary source documents- the great bulk of which have remained unknown to most modern researchers- are of capital importance for study of this seminal period in church history. Volume 1 records the activity of the Consistory between 1542 and 1544. Arbitration of disputes, surveillance of morals, repression of the vestiges of the Catholic cult, promotion of the Reformed mode of living, resolution of matrimonial cases- this is a general sketch of the Consistory's work during its earliest days. Rich in details pertaining to daily life and piety in Geneva, these noteworthy historical documents testify to the immense role played by the church in society at the beginning of the Reformation.
