Theodotus of Byzantium

Theodotus of Byzantium was a dynamic monarchian theologian from Byzantium, one of several named Theodotus whose writings were condemned as heresy in the early church.
Theodotus held the profession of a leatherworker or fuller in Byzantium. He taught that Jesus was a virgin born man and, though he later received the spirit of God upon baptism, he was not himself God until after his resurrection. This Christology, now referred to as "Dynamic Monarchianism" by modern scholars, was declared heretical by Pope Victor I, and Theodotus was excommunicated. Eusebius in referencing Theodotus' beliefs, refers to the group calling the correct "preaching have been delayed" ultimately "until the times of Victor". He argued that " if Victor agreed with their opinions", why were they cast out? Meanwhile, Hippolytus lists Theodotus's denial of Christ during persecution as the reason for his beliefs.
Ultimately, Theodotus' following seems to have been quite small, and later having a "fruitless attempt" at establishing a church in Rome.
