“Minister” From Concise Bible Dictionary:

The word commonly occurring in the Old Testament is sharath, “to minister, serve.” Joshua was Moses’ minister. All God’s hosts are called “ministers of his, that do his pleasure,” and He maketh “his ministers a flaming fire.” The priests were the ministers of Jehovah (Josh. 1:1; Psa. 103:21; Psa. 104:4; Joel 2:17). In the New Testament three words are used.
1. διάκονος. See DEACON.
2. λειτουργός, “a public servant,” one holding an official position. It is applied to the Lord; to angels; to Paul; and to magistrates (Rom. 13:6; Rom. 15:16; Heb. 1:7; Heb. 8:2).
3. ὑπηρέτης, literally “under-rower,” and so an “attendant” on, or “assistant” to a superior authority (Luke 1:2; Luke 4:20; Acts 13:5; Acts 26:16; 1 Cor. 4:1). It is also translated “officer” and “servant.”

“Officer” From Concise Bible Dictionary:

This word is used in scripture indefinitely for any one in authority, there being seven Hebrew words so translated. In the New Testament are
1. πράκτωρ, from “to do or act,” it occurs only in Luke 12:58. It is used for the officer appointed to exact the money adjudicated by the judge.
2. ὑπηρἐτης, literally “an under-rower,” a subordinate officer, who assisted the priests and the Roman governors (Matt. 5:25; John 7:32,45-46; John 18:3-22; John 19:6; Acts 5:22,26). It is also translated “minister” and “servant.”
