The Three Degrees of Holy Orders
The Orthodox Church has maintained, from its earliest days, a threefold ordained ministry: deacons, priests (presbyters), and bishops. This structure is not a historical accident or an administrative convenience — it was established by the Apostles themselves and reflects the structure of the Church as the Body of Christ with its various members and functions.
The bishop stands at the fullness of the priesthood. He is the successor of the Apostles, the guardian of the faith in his diocese, and the visible link to the apostolic succession. Without a valid bishop, there is no valid Eucharist, no valid ordination, and no local church in the full Orthodox sense. The bishop is the source of the sacramental life of his diocese: the priests he ordains act as his representatives in the local parishes.
"Where the bishop is, there let the multitude of believers be; even as where Jesus Christ is, there is the Catholic Church." — This ancient principle binds the local community to its bishop and through him to the whole Church.
Priesthood: Service, Not Power
The priest (presbyter) serves as the pastor of a local parish. He celebrates the sacraments, preaches, teaches, counsels, and intercedes for his flock. In Orthodoxy, a parish priest is typically a married man who was ordained after marriage; the monastic (celibate) clergy can be elevated to higher offices including the episcopate. Both married and monastic priesthood are equally valid and equally holy — they represent different vocations, not different levels of sanctity.
The deacon assists the bishop and priest, particularly in the celebration of the Divine Liturgy. He proclaims the Gospel, leads the litanies of prayer, assists at the altar, and serves the poor — recovering the ancient office described in Acts 6, where the first deacons were appointed to serve the material needs of the community.
The Ordained and the Royal Priesthood
The ordained priesthood does not replace or diminish the royal priesthood of all the baptized — it serves it. The priest at the altar is not offering sacrifice instead of the people but with them and on behalf of them. The entire congregation is a priestly body offering the world to God; the ordained priest makes that offering possible by sanctifying the gifts. Both forms of priesthood are necessary; neither can stand without the other.
The priest stands before God on behalf of the whole people. What an awesome dignity! What a terrible responsibility! One trembles to think of it.
