Patres Patrum [1]
(Lat. for Fathers of the Fathers), a designation sometimes given to bishops in the ancient Christian Church. Gregory of Nyssa was called by this name in the canons of the second Council of Nice; and others say that Theodosius, the emperor, gave Chrysostom the same title after death. (See Patres).
