Part I Protheoria: Origins of the Sacramentarian schism — Luther, Carlstadt, Zwingli (1524)

And would that men went back to the first Origins of the dissensions, understood at length from the History of the Diffidence — first the Sacramentarian schism, born in the year 1524 between Luther and Carolostadius, otherwise Bodenstein of Carlstadt, with Huldrych Zwingli soon about to move into a middle opinion: namely, Carolostadius referring the This (τοῦτο) in the words of Institution not to the Bread but to the Body of Christ, and so removing every presence of the Body in the Eucharistic Bread; Luther on the contrary asserting a corporal presence, by the letter of the text (τοῦ ῥητοῦ); but Zwingli and Oecolampadius a Sacramental presence, under the figure of Bread and Wine.
