Effrontes

Cyclopedia of Biblical, Theological and Ecclesiastical Literature

an obscure Transylvanian sect of the sixteenth century, who not only denied the Holy Ghost, but, among other fooleries, cut their foreheads and anointed them with oil as a mode of initiation. Hence their name "exfrons" out of the brow (Eadie, Eccl. Cyclop. s.v.).
