Pedigree of the Patriarchs of Antioch

Antioch is where the disciples of Christ were first called Christians.

Acts 11:26 And when he had found him, he brought him unto Antioch. And it came to pass, that a whole year they assembled themselves with the church, and taught much people. And the disciples were called Christians first in Antioch.

There is an unbroken list of the Patriarchs of the Church of Antioch down to the present day (OrthodoxWiki: List of Patriarchs of Antioch).

This is one element of Apostolic Succession. Christ left a Church and it is still here today.

His Beatitude Patriarch John X (Yazigi) of Antioch and All the East is the primate of the Church of Antioch.
