Sacramentarians, the name given to those who during the Reformation controversies not only denied the Roman Catholic transubstantiation, but also the Lutheran sacramental union. They comprised two parties: 1. * the followers of Capito, Carlstadt and Bucer, who at the diet of Augsburg presented the Confessio Tetrapolitana from Strassburg, Konstanz, Lindau and Memmingen 2. * the followers of the Swiss reformer Zwingli, who to the same diet presented his private confession of faith.
