Hippolytus' commentary starts in Book 9 Chapter 8.[4] In his next section, Hippolytus recounts that Alcibiades teaches the natural birth, preexistence and reincarnation of Jesus which may relate, per Louis Ginzberg (1906) to the kabbalistic concept of Adam Kadmon,[5] and also that Alcibiades teaches circumcision and the Law of Moses.[4] Hippolytus then goes on at length to describe the group's teaching on baptism.
