The Father gives the Son to the world. God presents the world with this gift of himself in the person of the Son. Then, when many ages have passed, the perfected world presents the Son to the Father, by the Spirit. The Son will present the world, in the form of the church, to the Father, to receive his inspection and approval. But the Son also continually presents the first installments of the future world, the perfected creation, to the Father. The future world is entirely present to the Father in the Son. It is created by that conversation and continuously opened by the Spirit who sustains their conversation. The future and completed world is continually given to the present world by the Spirit in the church, which is itself the body of the Son for the world. The Spirit stands in for the future act of the world. Where the world is going to be one day established in its own free and joyful activity, there the Spirit is now, representing it and preparing it for this future. The someday competent world will accompany the Spirit; it will take the action the Spirit gives it and, in the company of the Spirit, it will take what is the Spirit’s and return it via the Son to the Father. In that joint act of Spirit and world, the world will become living, active, and free.
The church is the visible tip of the not yet visible company of heaven. This company is held together by God, and made visible by him to us on earth. The church understood on this eschatological definition, holds together what would otherwise drift apart. The church sustains the world, which has no unity of its own, and so the church represents that future in which the world will be spacious and free. In raising Jesus Christ, and calling out the church, God has elected the human race. He has made the church to be the body that embodies and guarantees both plurality and unity for the world. As the church is itself the work of the Spirit, it works this priestly task of bringing the world together around the Son.
