Sabellianism, Sabellianism

It was coined by Tertullian in his work Adversus Praxeas , Chapter I, "By this Praxeas did a twofold service for the devil at Rome: he drove away prophecy, and he brought in heresy; he put to flight the Paraclete, and he crucified the Father." It is important to note that our only sources extant for our understanding of Sabellianism are from their detractors. Scholars today are not in agreement as to what exactly Sabellius or Praxeus taught. It is easy to suppose Tertullian and Hippolytus misrepresented the opinions of their opponents.
