The name given to that school of the Protestant Church which accepted Luther's doctrine, especially that of the Eucharist, in opposition to that of the members of the Reformed Church, who assented to the views in that matter of Zwingli, the Swiss Reformer; the former maintaining the presence of Christ in the Eucharist, and that the grace of Christ is communicated in the celebration of it, and the latter maintaining that it is a merely commemorative ordinance, and the means of grace to the believing recipient only.
