Note 430 — Chapter IX · POST-CHRISTIAN GNOSTICS: VALENTINUS
Reading edition
R.H.R. Jan.-Fev. 1891, p. 27. Tertullian’s own heresy was of course Montanism. Harnack, Hist. of Dogma, Eng. ed., II. pp. 257, 258, says indeed that Hippolytus’ own views of the Trinity coincide with those of Valentinus and are a relic of polytheism.
