Calixtines [1]

(1). In the year 1420, the Hussites divided into two great factions, the Taborites and the Calixtines. The latter, who derived their name from the chalice (Calix), asserted that communion in both kinds was essential to the sacrament. They are not generally ranked by Romanists among heretics, for many of them were persuaded by the concessions of the Council of Basle, in 1493, to be reconciled to the Roman pontiff.' The reformation they aimed at extended principally to four articles:

1. To restore the cup to the laity.

2. To subject criminal clergymen to the civil magistrate.

3. To strip the clergy of their lands, lordships, and all temporal jurisdictions.

4. To grant liberty to all priests to preach the Word of God. -Mosheim, Ch. Hist. 2: 459; Farrar, Ecclesiastes Dict. s.v. (See Bohemia); (See Hussites).

(2.) Followers of George Calixtus. (See George Calixtus).
