 Calvin answered in January 1555, with his "Defensio sanae et orthodoxae doctrinae de sacramentis".Thus there was opened a controversy which involved on the side of the Reformed Lasco, Bullinger, Ochino, Valerandus Polanus, Beza, and Bibliander; on the side of the Lutherans Timann, Paul von Eitzen, Schnepff, E. Alberus, Gallus, Flacius, Judex, Brenz, and Andreä.Westphal replied to Calvin in "Adversus cuiusdam sacramentarii falsam criminationem iusta defensio, in qua et eucharistiae causa agitur" (1555), to which Calvin answered in "Secunda defensio piae et orthodoxae de sacramentis fidei" (1556), which was an attempt to draw to his side the Philippists of Saxony and Lower Germany.
