In carrying out the Great Commission the original twelve deployed their apostolic, prophetic, evangelistic, pastoral and teaching gifts to draw people to faith in Christ. Those so drawn were put in clusters under the temporary care of overseers to nurture them to stand on their own.
Overseers did not belong to the local church but moved from one house church to another house church as it was considered expedient for disciplining new converts.
Originally, there was no clergy-laity dichotomy in the local assembly. They were all brethren.
The purpose of the house church was to function as nursery to nurture and grow believers from babyhood to maturity in Christ.
The Holy Spirit Himself was in charge of house churches. The joy of fellowship was the fact that the Holy Spirit was totally in control of proceedings.
“And He Himself gave some to be apostles, some prophets, some evangelists, and some pastors and teachers, for the equipping of the saints for the work of ministry, for the edifying of the body of Christ, till we all come to the unity of the faith and of the knowledge of the Son of God, to a perfect man, to the measure of the stature of the fullness of Christ.” (Eph 4:11-13)
In the days of the Apostles those with pastoral calling had no direct role to play in the local house church other than to transmit messages and divinely-received teachings to them through overseers sent to establish them in the faith.
For the house church established by the Holy Spirit and enrolled mostly through fruits of evangelism qualified men and women were given appointments in the church. “And God has appointed these in the church” Apostles, Prophets, Teachers, Workers of miracles, Healers with – gifts of healing, Helpers, Administrators, Speakers with tongues & Interpreters of tongues.
House church Apostles, Prophets and Teachers were not the same as those in the five-fold ministry. Their ministry was not worldwide but limited to the place they were ordinarily resident with the cell as their base.
From maturing appointees ‘elders’ were chosen to manage the cell in the absence of the overseers that move to new centres. They in turn could be assigned to new cells as overseers.
In the early church, every member of a house church was endowed with at least one of these nine gifts to function in the local assembly. They were not ordained by ‘anointed’ men of God. They simply stirred the gift bestowed to them and carried out the enablement in the local assembly of believers and their environment.
They did not carry the titles like bracelets. Some functioned in more than one appointive position.
The twelve Apostles appointed from the men who followed them overseers of house churches. They were required to move from house church to house church establishing the new appointees in their roles in the church and strengthening them to continue in the grace of God.
