The purpose of the ministry of Evangelists and Pastor-Teachers is to support the rest of the ministries of church – for the equipping of the saints for the work of service to the building up of the body of Christ (Ephesians 4:12). Evangelists deal with the beginning of the Christian life while the Pastor-Teacher is involved with the development and growth of that life. Evangelists are much like obstetricians helping to bring new Christians into the world. Teaching Pastors are like pediatricians seeing that these Christians have a healthy spiritual diet so that they will be nourished, healthy, and grow.
