Praxeas

Praxeas was a Monarchian from Asia Minor who lived in the end of the 2nd century/beginning of the 3rd century. He believed in the unity of the Godhead and vehemently disagreed with any attempt at division of the personalities or personages of the Father, Son, and Holy Spirit in the Christian Church. He was opposed by Tertullian in his tract, Against Praxeas (Adversus Praxean), and was influential in preventing the Roman Church from granting recognition to the New Prophecy.
