Acts 6:2-4 (King James Version)
2Then the twelve called the multitude of the disciples unto them, and said, It is not reason that we should leave the word of God, and serve tables.
3Wherefore, brethren, look ye out among you seven men of honest report, full of the Holy Ghost and wisdom, whom we may appoint over this business.
4But we will give ourselves continually to prayer, and to the ministry of the word.
The Apostels set the standard for how this should be done. The pastors should give themselves contunually to prayer and ministry of the word, while the church membership should appoint those that will serve tables (meeting the needs of the church membership) so that the pastor is not distracted from his family and his primary responsability of prayer and preaching.
