A short job description for each of the 5 fold ministry in Ephesians 4:11

Apostles: Train and then commission for ministry Prophets: Discern and confirm gifts in others. Intercede to see the plans and purposes of God. Evangelists: Win souls and turn them over to the pastors and teachers for discipleship . Pastors: Disciple and nurture the new believers. Teachers: Bring believers to maturity for the work of the ministry. Apostles: Close the circle by commissioning a new crop of believers into their place of ministry.

Besides these descriptions in simple terms the church has basically 3 functions beside worship and praising the Lord. 1. To win souls. 2. Make disciples. 3. Send out workers. Then it begins all over again with winning souls. Its simplistic but covers most of what we do.
