‘What a joy to see the study of liturgy and with it the church's life of worship, taken with such seriousness. The breadth of the essays gathered in this Festschrift, and the scholarly commitments displayed here, witness to the vibrancy of this field of inquiry. Here is liturgical studies at its best - deeply engaged with historical questions, theological convictions, and contemporary practices.' - Teresa Berger, Yale Institute of Sacred Music and Yale Divinity School, New Haven, CT, USA
