This concept of the complementary relationship between the ordained and the unordained should inform the church's gathered life. The sermon, the preparation for church membership, all adult education programs, and the general ministry of the church, need to be conditioned by the thought that the purpose of the official teachers and preachers and administrators of the church's program is to prepare and guide the people of God in the performance of their work _in the world_, as representatives of Christ there. Resources need to be created in the church's program whereby people can come back from their ministry in the world, be helped to understand what has happened, and by reflection upon it learn how more effectively to be the church in the world. For this reason, seminars for parents need to be held in order that they may receive assistance in understanding their role as ministers of the church in the home. Seminars for businessmen and professional people also are indicated for the same reason. A point of focus for all church membership courses should be the question: When you become a member of the church, how are you going to exercise your ministry in the world? This orientation could be the source of a new evangelism that would make its witness heard in the depth and detail of human life. _The Reunion of the Church_ We turn now to consider some of the implications of what we have been thinking for the reunion of the church. If the church is the instrument of God's action in the world, and its members are supposed to be the incarnations of His Spirit by means of which He accomplishes His purpose, the condition, as well as the concept of the church, is important. One of the tragedies of Christendom is the fact that the body of Christ is so divided and its parts live in such competitive relationship that the purposes of God are obscured and blocked. Movements toward reunion have borne fruit, with the result that some denominations have resolved their differences and reunited. But much more progress needs to be made, if the church is to be equal to the demands that modern life is making on it for spiritual leadership.
