If salvation makes a person to become God, then how do we understand the word 'God'? Audy Santoso assesses Robert Jenson's notion of deification on three main areas: the concept of God, Christ, and self along with their ramifications. In this comparative study, Jenson's revisionary metaphysics in his theology opens up an insightful perspective in reading John Calvin's theology. Discussion on the Supper shows the intricate relation of what these theologians hope for with the practice of our lives in God. The author makes a comparative assessment and integration between the seemingly opposite metaphysics of Jenson and Calvin while keeping the Creator-creature distinction of Reformed theology intact. Jenson says that the end is music, but the author affirms a better way without negating Jenson's.

A significant number of Muslim communities throughout the world reflect varying degrees of involvement in Islamic mysticism. What bridges are present in this context that will facilitate not only evangelism, but also discipleship and community formation? Matthew Friedman guides the reader on a journey examining the response of the early Christian community to the challenges of ancient Jewish and Hellenic mysticism, focusing on the central idea of “union with God in Christ.” Far from finding this to be a leftover from the early Church, he discovers that this theme remained crucial into the Reformation, particularly in the writing and work of eighteenth-century figures John and Charles Wesley.Join Friedman as he explores resources for discipleship and community building that will be relevant to both scholars and practitioners alike, and will be effective for witness within modern contexts of Islamic mysticism worldwide.

The complex nature of Christian communion with a personal God requires a nuanced expression. Since its inception, the early church affirmed God's unknowable nature and also participation in God through Christ. The church fathers employed the language of theosis in talking about union with God and human transformation in the likeness of God. However, the term theosis or deification is a broad category and requires precise explanation to avoid human dissolution in the divine in the mystical union. This book addresses the conundrum of imparticipable divine nature and personal union between human and the Trinity. If God is Trinity, then we are created and restored in the image of tripersonal God.

Christian Character Formation investigates worship and formation in view of Christian anthropology, particularly union with Christ. Traditions which value justification by faith wrestle to some degree with how to describe and encourage ethical formation when salvation and righteousness are presented as gracious and complete. The dialectic of law and gospel has suggested to some that forgiveness and the advocacy of ethical norms contend with each other. By viewing justification and formation in light of Christ's righteousness which is both imputed and imparted, it is more readily seen that forgiveness and ethics complement each other. In justification, God converts a person, by which he grants new character. Traditional Lutheran anthropology says that this regeneration grants a new nature in mystical union with Jesus Christ. By exploring the Finnish Luther School led by Tuomo Mannermaa, Gifford A. Grobien explains how union with Christ imparts righteousness and the corresponding new character to the believer. Furthermore, as means of grace, the Word and sacraments are the means of establishing union with Christ and nurturing new character. Considering Oswald Bayer's "suffering" the word of Christ, Louis-Marie Chauvet's "symbolic order" and Bernd Wannenwetsch's understanding of worship as Christianity's unique "form of life," Grobien argues that worship practices are the foundational and determinative context in which grace is offered and in which the distinctively Christian ethos supports virtues consistent with Christian character. This understanding is also coordinated with Stanley Hauerwas's narrative ethics and Luther's teaching of virtue and good works in view of the Ten Commandments.
