"As to be expected, Kevin Irwin circles an almost overwhelming array of topics in liturgy around the ever present, ever new, dance between liturgy and theology. Is it liturgy shaping theology or theology shaping liturgy? It is these two, plus endless nuances of how the two are actually different expressions of the same reality-expressing and creating meaning. Structurally this large book is remarkably clear, introducing each area with a manageable overview before launching into the concepts further enfleshed by case studies of euchology, Scripture texts, or feasts and seasons of the liturgical year. The augmented section on time and the arts (liturgical ministry, music, and architecture) simply concretizes in new and engaging ways the breadth of what 'text' means, and raises new questions about liturgical presiding as art, about music as ministerial practice, and about the context of space and place as full participant in the liturgical act."
