In Worship, Its Theology and Practice, Jean-Jacques von Allmen establishes the broader framework of a doctrine of worship, to then see how it can be applied in practice. The book's two parts, 'Problems of Principle' and 'Problems of Celebration', allow for a holistic approach to worship in all its forms. Covering a wide range of liturgical study, von Allmen places regular Sunday worship in its historical and theological context, affirming its nature as the 'recapitulation of the history of salvation' and a sacred sign of Christ's presence, while fully acknowledging its practical role in building the Church. In this new edition, von Allmen's work is brought up to date with a Foreword by Ronald Andrew Rienstra. There is also a new index, enabling scholars to locate key concepts and themes with ease. At its core, Worship, Its Theology and Practice remains acutely relevant, with its vision of an experience of worship comprised of deeper participation and simple obedience to Jesus Christ.
