The Spirit in the Church: The Universal Christ, Particular Spirit and Christian Unity

Modern theology has had difficulty in producing an ecclesiology that makes the full visible unity of the church an essential aspect of the church's nature. One reason for this is that important modern ecclesiologies are built on a trinitarian model that either subordinates the Spirit to the Son, or reduces the Spirit to a vague, invisible 'domain of resonance', with the result that the church itself is either subordinated or rendered invisible. A new trinitarian model is needed, one that shows how the Spirit cooperates with the Son to produce a visibly united church.
