The debate began 14 January 1541. The Augsburg Confession as the basis of the conference; the Augsburg Confession of 1540 was a different document from the Confession of 1530, having been changed by Melanchthon to suit his sacramentarian view of the Eucharist. Eck and Melanchthon battled four days over the topic of original sin and its consequences, and a formula was drafted to which both parties agreed, the Protestants with a reservation.
