Marcionism

Marcionism was a type of Christianity that started around 144 C.E.According to Tertullian in Adversus Marcionnem, it started 115 years and 6 months after the Crucifixion of Jesus. It was started by Marcion of Sinope in Rome. He believed in Jesus Christ but did not accept the Bible or Yahweh. He was a dualist and believed that the god who wrote the Old Testament was different from the god who wrote the New Testament. 

Traditionally, members were required to wear pointed-head garments to show reverence to the god of the Old Testament.
