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' allows 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. At its core, Worship, Its Theology and Practice envisions an experience of worship with deeper participation and simple obedience to Jesus Christ.
