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.
