According to the Canon 1 of the Apostolic Canons, the Consecration of a Bishop must be accomplished by three or more Bishops.
After his Consecration, if he is elected to be a ruling Bishop of a Diocese, he is formally enthroned (installed) as the ruling Bishop by the Senior (Consecrating) Bishop. The enthronement usually takes place at the end of the Consecration Liturgy.
The Consecrating Bishop leads the newly ordained Bishop through the Royal Doors to the congregation and then bestows upon him the final liturgical items associated with the Episcopacy. With the bestowal of each liturgical item he exclaims: Axios! (He is worthy!)
The congregation responds each time, "Axios! Axios! Axios!" (He is worthy!) The Archbishop presents him with the Pastoral Staff, the emblem of Episcopal authority that the Church entrusts to him, saying: Receive this Staff to shepherd the flock of Christ entrusted to you. To the obedient let it be a help and a support. With it, lead the disobedient and the wayward to admonishment and instruction.
The newly ordained Bishop is led by the Bishops to his Episcopal Throne where he pronounces the final blessing of the Divine Liturgy, to which the faithful respond Eis Polla Eti Despota – Many Years Master!
