A bishop is the fullness of the orthodox priesthood. All bishops are equals but some are given the title of Archbishop, Metropolitan, Patriarch, or Pope. All of these titles are honorific and administrative. They do not diminish the equality of all bishops as vicars of Christ and successors of the Apostles.
The priest who is to be consecrated a bishop is lead through the Holy Doors, by a bishop, during the Divine Liturgy and kisses the main consecrators hand asking his blessings. The bishop leads him around the Holy Table as the he kisses the four corners. This is repeated three times. Then the candidate kneels and the bishops lay their hands on his head and the Gospel book is held above their hands. Then the prayers of consecration are chanted. After this the new bishop is vested in his episcopal vestments. After each piece of vestments is placed on the new bishop the people chant “Axios,” Greek for “He is worthy.”
What I found most powerful was the symbolism of the Gospel book laying open over the head of the priest being ordained a bishop -- a powerful visual reminder that the only authority of the Church and of the bearers of the offices of the Church is the Word of God. I almost long to have such a rite introduced into our Western Lutheran ordination order for it surely and powerfully proclaims what we believe, teach, and confess -- that the authority of the Church and of the Pastoral Office is nothing less and nothing more than the authority of this Word of God.
BTW isn't the singing simply marvelous!
