Holy Orders is the sacrament through which the mission entrusted by Christ to his Apostles continues to be exercised in the church. it includes three degrees: diaconate, presbyterate and episcopate.
Episcopal consecration of a bishop confers the offices of sanctifying teaching and ruling. Priests are consecrated to preach the Gospel and to shepherd the faithful, as well as to celebrate the divine liturgy.
Deacons share in Christ's mission and grace. Among other tasks, deacons assist the bishop and priests in the celebration of the divine mysteries, and in dedicating themselves to the various ministries of charity.
