But there is no record of either Christ nor the Apostles having laid hands upon Ananias. So the break occurred there, and Paul wouldn't have been able to ordain the Presbyters that he did.
Let's see. Your initial logic is such that, if the Bible doesn't say that Jesus typically ate breakfast, then Jesus never ate breakfast. My initial logic is such that, if the Lord Jesus Christ Himself sent Paul to Ananias to receive the laying on of hands, there's a PRETTY good chance Ananias was authorized to do so.
But then, that's all moot, because according to Orthodox tradition, Ananias WAS the bishop of Damascus, which he could not be if he had not had hands laid upon him by one of the Apostles. Thus, apostolic succession is not broken here. Additionally, the Orthodox also hold that Ananias was one of the "seventy" disciples sent out by Christ to evangelize in the Gospel of Luke.
He may have been one of the forty (or forty two, depending on source). If succession is the ticket, one has to wonder why the record keeping for many of the Sees are so sparse & lists of holders "gathered" centuries after the fact. How many of the forty walked away at the Crucification?
Correction, seventy or seventy two.
