To serve as hosts and helpers in the Lord’s House; to represent Christ to all who gather to worship and praise God and fellowship with each other.
Psalm 84:10; Acts 1:8
Persons were appointed to keep the street door leading into the interior of a house John 18:16-17; Ac 12:13 Sometimes females held this post.
The ministry of the usher goes far beyond opening a door. Since ushers are usually the first point of contact for all who enter the worship facilities, their principle function is that of host of the building and representing Christ to believers and strangers who gather to worship and praise God and fellowship with each other.
