The Decades of Henry Bullinger, Minister of the Church of Zurich
Henry Bullinger (1504-1575) was one of the most widely esteemed leaders of the Reformed churches, and The Decades was the most famous of his 150 treatises and manuscripts. The Decades derives its name from being a series of fifty theological sermons divided into five groups of ten sermons each. Each sermon is a helpful, detailed exposition of an important doctrine. Combined, they encompass the field of theology in a form readable for the typical layman. They became more popular than Calvins Institutes in England.
