Special “Episcopal training” in the Ecumenical Patriarchate?

To the rest of the world, this may seem a bit redundant. If the Ecumenical Patriarchate views a person or people worthy of being consecrated to the episcopacy, what further training is needed to fulfill their duties as bishop? We are at a loss. The “job” of the bishop within the Orthodox Church is outlined by the holy Fathers, Our Lord Jesus Christ, the Sacred Canons and the Holy Saints. What more is possibly needed? May we suggest “Chastity, Humility, and Patience”? Surely bishops need these traits to guide their flock and keep them away from the Evil One. But alas, let us remember the deposed Patriarch Meletios IV (Metaxakis) whom reigned terror in the Orthodox Church as Ecumenical Patriarch, Archbishop of Athens, and finally the Pope and Patriarch of Alexandria and all Africa.
In the words of the late Patriarch Athenagoras, quote, “Chastity, Humility, and Patience are good, but only for monastics.” (Pastoral Letter to Archbishop Iakovos, Primate of the Greek Archdiocese of America, October, 1960)
