Pneumatomachi

The Pneumatomachi (Greek: Πνευματομάχοι), also known as Macedonians or Semi-Arians in Constantinople and the Tropici in Alexandria, were an anti-Nicene Creed sect which flourished in the countries adjacent to the Hellespont during the latter half of the fourth, and the beginning of the fifth century. They denied the Godhead of the Holy Ghost, hence the Greek name Pneumatomachi or 'Combators against the Spirit'.
