S. Baring-Gould, The Lost and Hostile Gospels
“ Marcion was too conscientious and earnest a man wilfully to corrupt a Gospel. He probably brought with him to Rome the Gospel in use at Sinope in Pontus, of which city, according to one account, his father was bishop. The Church in Sinope had for its first bishop, Philologus, the friend of St. Paul, if we may trust the pseudo-Hippolytus and Dorotheus. It is probable that the Church of Sinope, when founded, was furnished by St. Paul with a collection of the records of Christ's life and teaching such as he supplied to other “Asiatic” churches. ”
