They denied the Godhood of the Holy Ghost, hence the Greek name Pneumatomachi or 'Combators against the Spirit' (from πνεῦμα pneuma, spirit + μάχη machē, battle).
Nijekali su božanstvo Duha Svetoga, pa odakle dolazi grčki naziv Pneumatomachi ili 'Combators protiv Duha' (od πνεῦμα pneuma, duh + σάχη machē, bitka).
