Note 69 — BOOK IX NOETUS, CALLISTUS, AND OTHERS
Francis Legge translation
If this Theodotus is, as seems probable, the Theodotus of Byzantium mentioned in Book VII (p. 390 Cr.), who was excommunicated by Victor, his heresy was, as Hippolytus himself records, Adoptianist, and his opinions must have been poles asunder from those of Callistus.
