 Marcion was well-known for preaching that the god who sent Jesus into the world was a different, higher deity than the creator god of Judaism.While no manuscript copies of Marcion's gospel survive, reconstructions of his text have been published by Adolf von Harnack and Dieter T. Roth, based on quotations in the anti-Marcionite treatises of orthodox Christian apologists, such as Irenaeus, Tertullian, and Epiphanius.These early apologists accused Marcion of having "mutilated" canonical Luke by removing material that contradicted his unorthodox theological views.
