Deacon

A deacon is a member of the diaconate, an office in Christian churches that is generally associated with service of some kind, but which varies among theological and denominational traditions.

Major Christian denominations, such as the Catholic Church, the Oriental Orthodox Churches, the Eastern Orthodox Church, Lutheranism, Presbyterianism, Methodism, and Anglicanism, view the diaconate as an order of ministry.

Quotes

Likewise deacons must be reverent, not double-tongued, not given to much wine, not greedy for money, holding the mystery of the faith with a pure conscience. But let these also first be tested; then let them serve as deacons, being found blameless. Likewise, their wives must be reverent, not slanderers, temperate, faithful in all things. Let deacons be the husbands of one wife, ruling their children and their own houses well. For those who have served well as deacons obtain for themselves a good standing and great boldness in the faith which is in Christ Jesus.

Paul the Apostle in 1 Timothy 3:813 NKJV.

We then call the diaconate and the priesthood sacred orders. In fact, we read that the early Church had only these; only in reference to these do we have a command from the Apostle.
