This book presents two new proposals regarding Paul’s letter to the Galatians. First, it demonstrates an entirely new chiastic structure embracing the entire letter, based on strict linguistic and textual criteria rather than on conceptual or theological themes. This chiastic structure accords with the view that Galatians was originally performed orally in a setting of communal worship. Secondly, it offers a new proposal for a key theme that runs throughout Galatians, as expressed by the subtitle of this book–Worship for Life by Faith in the Crucified and Risen Lord. It considers worship to be a comprehensive concept that includes liturgical, cultic, or ritual worship as well as the moral behavior that is to complement it as ethical worship in accord with the biblical tradition. Life refers both to the present way of living as well as to future eternal life. Faith refers to the acceptance of divine grace available to the believer because of the death and resurrection of the Lord Jesus Christ.
