"Tony Costa offers here a thoughtful and intensive investigation of worship as reflected in the Pauline Corpus. His particular contributions lie in his detailed analysis of the vocabulary of worship in Paul, and in his engagement with other scholarship. His work comprises a genuine contribution to the analysis of the religious life of earliest Christianity." (Larry W. Hurtado, Professor Emeritus, New Testament Language, Literature and Theology, University of Edinburgh, Scotland) "Tony Costa's work helpfully reviews scholarship and most importantly provides in-depth exploration of Paul's Christocentric approach to worship. This work offers fresh insights on worship from a biblical perspective and makes a vital contribution to the subject." (Craig S. Keener, Professor New Testament, Asbury Theological Seminary, Wilmore, Kentucky) "In this ground-breaking study on the concept of worship in the early Church, Tony Costa explores the phenomenon by going back to the earliest New Testament writer, Paul. He explores the various words, expressions, and ritual actions of worship offered by Paul in his letters, then proposes a comprehensive definition of worship and criteria for identifying it. Costa calls attention to the fact that, for Paul, acts of worship are not as limited as we may have imagined. I find especially valuable Costa's treatment of the integral role of Jesus within the worship experience of the Pauline faith communities. This has profound implications, suggesting a very high Christology within the early Church. Costa brings a fresh perspective, and I recommend this book to those interested in the area of earliest Christian worship and Christology." (Michael R. Licona, Associate Professor of Theology, Houston Baptist University, Houston, Texas) "The corpus of the Apostle Paul is the oldest body of Christian literature, and the way that he approaches the person of Christ in relation to worship is therefore of supreme significance. In this new work, Tony Costa presents a detailed argument for seeing the writings of the Apostle Paul as the first in a long line of Christian works that have found the raison d'etre of human existence in the worship of the Lord Jesus Christ. His argument is sound and deeply persuasive and provides cogent proof that the Church's ascription of deity to Jesus of Nazareth has been right and true. I wish it a wide reading and impact."
