The unifying centre of Nicholas J. Healy’s book is an analysis, in dialogue with the metaphysics of Thomas Aquinas, of Balthasar’s understanding of the analogy of being. This discussion of analogy is framed by an interpretation of Balthasar’s trinitarian eschatology. Healy shows that the ultimate form of the end, and thus the measure of all that is meant by eschatology, is given in Christ’s eucharistic and pneumatic gift of himself - a gift that simultaneously lays bare the mystery of God’s trinitarian life and enables Christ to ‘return’ to the Father in communion with the whole of creation.
