What was the impact of liturgy on the development of orthodox doctrine in the early Christian church? With renowned liturgical historian Maxwell E. Johnson as a guide, readers of "Praying and Believing in Early Christianity" will discover the important and sometimes surprising ways that worship helped to shape what was believed, taught, and confessed. In particular, Johnson considers this relationship in terms of soteriology: What is the role of grace in the process of salvation? Trinity: How did early devotion to Christ and the church's baptismal and eucharistic liturgies help shape the developing doctrine of the Trinity? Christ and Mary: What does the devotional and liturgical term theotokos say about them both? ethics: How does the liturgy contribute not only to doctrine but also to convictions about morality? Johnson also explores the ways this relationship worked in the opposite direction: How did doctrinal developments shape liturgical texts in the patristic period? This is an excellent text for beginning students in liturgical studies at the master's level.
