Serapion died c. 211 AD. He was the 8th bishop of Antioch and served in that role c. 190-211. He spoke against Marcion and against the so-called Gospel of Peter.
Of the apostles, Serapion said:
For we, brethren, receive both Peter and the rest of the apostles as Christ Himself. But those writings which are falsely inscribed with their name, we as experienced persons reject, knowing that no such writings have been handed down to us.
