The American Church Dictionary and Cycopedia
One who has been ordained to the lowest order of the Ministry. The account of the institution of the order of Deacons is found in the Acts of the Apostles 6:1-7. We here learn that the first Deacons were ordained to attend especially to the benevolent work of the Church in caring for the poor, but they were also preachers of the Word. The Office of Deacon is still retained in the Church as an order of the Ministry, for "it is evident unto all men reading Holy Scripture and ancient Authors, that from the Apostles' time there have been these Orders of Ministers in Christ's Church,—Bishops, Priests and Deacons." A Deacon may assist the Priest at the Altar and administer the cup. He may baptize, say all choir offices, and if he is learned and is licensed thereto by the Bishop, he may preach, but he cannot administer the Holy Communion, or pronounce the Absolution and the Benediction. He wears his stole over the left shoulder and fastened under his right arm. If a Candidate for Priest's Orders and can pass the required examination, he may after a year's service as a Deacon be advanced to the Priesthood.
