In the acts of the Council of Chalcedon it is noted that the Church of Edessa had fifteen priests and thirty-eight deacons. And Justinian, we know, appointed one hundred deacons for the Church of Constantinople. Van Espen well points out that while this canon refers to a previous law on the subject, neither the Council itself, nor the Greek commentators Balsamon or Zonaras give the least hint as to what that Canon was.
