Most discussed subject in Reformation

Keith Mathison, Given For You (P&R, 2002):

One of the most interesting phenomena that one encounters when comparing the writings of the sixteenth-century with the writings of their twentieth-century heirs is the different amount of attention devoted to the Lord’s Supper. The Reformers devoted volumes of books, letters, tracts, and sermons to the subject. The sixteenth century was a time of heated controversy over such crucial doctrines as the authority of Scripture and justification by faith alone, yet the doctrine that was discussed more often than any other was that of the Lord’s Supper. In our own day, however, the Lord’s Supper is rarely the subject of books or sermons. (p.xv)

Zwingli’s own strictly memorialist view was generally disowned by the Reformed churches and confessions of the sixteenth century. However, from the seventeenth century onward, it has gradually become the dominant view in the Reformed church. (p.xvi)
