Tatian, Justin, Marcion and Marcus Agrippa

Tatian must have been connected to Marcion through Justin. Justin = Justus (don't believe the nonsense about him living in the Antonine period; that's just when Polycarp lived). I think Justin was Justus the secretary of Marcus Agrippa. Josephus reports a tradition where he "forged" certain documents in his name. I think this is the origin of the break. Justin is the Zadok mentioned in that Karaite writer whose name begins with a Q mentioned by Pines who is said to also believe in Jesus.
