35. 'Marcion cut Matthew 16:17 - 19'

The publican who was chosen by the Lord, [Luke 5:27] he adduces for a proof that he was chosen as a stranger to the law and uninitiated in Judaism, by one who was an adversary to the law. The case of Peter escaped his memory, who, although he was a man of the law, was not only chosen by the Lord, but also obtained the testimony of possessing knowledge which was given to him by the Father. – Tertullian expected to see Mt 16:17 [or possibly Mt 16:17-19] in the Marcionite gospel [Tertullian Adv Marc 4:11]
