(compounded of μόνος, "sin- gle," and θέλω, "will," of στέλλω, volo, "I will.") an ancient sect, which sprung out of the Eutychians; thus called, as only allowing of one will in Jesus Christ.

The opinion of the Monothelites had its rise in 632, and had the emperor Heraclius for an adherent: it was the same with that of the Acephalous Severians. They allowed of two wills in Christ, considered with regard to the two natures; but reduced them to one, by reason of the union of the two natures; thinking it ab- surd there should be two free wills in one and the same person. They were condemned by the sixth general council in 680, as being supposed to destroy the per- fection of the humanity of Jesus Christ, depriving it of will and operation. Their sentiments were afterwards embraced by the Maronites.
