Marcion of Sinope
Book VII challenges the teachings of such heretics as Basilides and his disciple Saturnilus, Marcion of Sinope, and Carpocrates of Alexandria, among others. These heresiarchs all held varying opinions on the God of the Old Testament, from Saturnilus, who Hippolytus states believed that "the God of the Jews is one of the angels", directly opposed by Christ, to Carpocrates who asserted that the Father was for the most part aloof from physical creation, which had been formed by his angels.
