No, I believe we don't have anything like that. I think a priest/bishop is just well known by his reputation and education without a special consecration. Fr. Tadros Malaty may be equivalent to a "Vartabed" as he is a leading authority in the Church for theological and Biblical education, but he's not really consecrated/ordained as a "doctor" of the Church. He is a hegoumenous, or an archpriest, just an honorary priestly title, and used also to denote the head of other priests in a parish (in this particular instant he is the head of priests in the Church in Sporting, Alexandria, Egypt), and he also has the special role of being summoned by the Pope to help churches around the world with no priests until they get a permanent priest (our church in Holmdel, NJ had the special privilege of having Fr. Tadros as our interum priest for about a year). By reputation, Fr. Tadros is also the brother-in-law of the late Fr. St. Bishoy Kamel, a recent saint in our Church (not canonized yet, but Copts all over the world seek his prayers).
Fr. Tadros will go down in history as a true scholar in our Church, and he is also known especially for his lengthy dissertation on Origen's life and beliefs.
