The Helvetic Confessions are two documents expressing the common belief of Reformed churches, especially in Switzerland, whose primary author was the Swiss Reformed theologian Heinrich Bullinger. The First Helvetic Confession (1536) contributed to the confessional unity of the Protestant cantons of Switzerland against the Roman Catholic cantons, whereas the Second Helvetic Confession (1566) contributed to the confessional unity of Reformed churches across Europe, particularly due to the patronage it received from Frederick III, Elector Palatine, who had it translated into German.[1]: 635 [2]
