Gnosticism was an early Christian sect that taught mysticism, rejected Jewish scriptures, such as the Hebrew Bible, and felt that Jesus' teachings, crucifixion, and resurrection were mere appearances. Jesus' true mission, they said, was to teach mysticism to his few devotees. One of those teachings was in the belief (if we compare it to Zorostriaiam which is similar) of an imperfect creator (Ahriman) who created the world and humans and that of the supreme G-d (or, Wise Lord) who sent Jesus (Zoroaster) to teach the ancient, mystical teachings. As a result, the Gnostics and bishops held many debates, no less fierce as debates between later Christian Catholics and Jews. For example, many bishops called Gnostics "empty ditches" which lacked water of truth flowing from within. The Gnostics similar called the bishops "wolves" who preyed on Christ's flock. The early bishops struggled against Gnostic "ravings," barring Gnostic writings from the New Testament.
My question is:
Where can one find debate(s) of early Gnostic and Chaotolic writings? I am aware of the Disputation at Barcelona between Jewish sage Nachmanides and Jewish convert to Christianity, Pablo Christiani in 1263 before the king of Aragon, James I. Do similar recorded debates exist between Gnostics and bishops?
 These were also the views of the pagan Greek philosopher, Plato.
 Or, we might compare the Gnostic and bishops' feud to the ancient Jewish sects called Sadducees and Pharisees who argued over the authenticity of Oral Law (Oral Torah).
