Heretics who denied the full Godhead of the Holy Spirit. They came to the fore in 373, when Eustathius of Sebaste became their leader. They were condemned by Pope Damasus in 374. At its peak, c.380, the sect contained a more conservative section which, while rejecting the Divinity of the Holy Spirit, accepted the consubstantiality of the Son, and a radical party which rejected this also. The Pneumatomachi were anathematized at the Council of Constantinople in 381 and soon disappeared.
