In this first volume of Sin, Grace and Free Will, Matthew Knell embarks on a journey through centuries of Christian thought, from the Apostolic Fathers to St Augustine of Hippo. While the themes of sin, grace and free will are familiar to any Christian, Knell provides a comprehensive overview of how people such as Irenaeus, Gregory of Nazianzus and Augustine explored these ideas, following the development of early church philosophy on topics such as the problem of evil and the crucial difference between conscious and unconscious sin, as well as the distinction between body and soul. An indispensable primer for any beginning scholar, Sin, Grace and Free Will presents the writings of Christian thinkers of the early church in context and examines the progress of church doctrine from the nascent model of sin in the Shepherd of Hermas to Origen's analysis of divine influence on human will and Augustine's seminal work on grace and salvation.

The fourth century was pivotal in the evolution of the feasts and fasts of late antique Christian communities. While earlier scholars have focused on developments in Jerusalem, Rome, and the Gallican West, the liturgical year in Cappadocia remains largely uncharted territory. Aspects of the Liturgical Year in Cappadocia (325 to 430) fills that gap, relying primarily on the liturgical year homilies of the Cappadocian Fathers in order to provide for the first time a comprehensive study of liturgical calendars from Cappadocia and environs during the period between the Councils of Nicaea and Ephesus. This volume is a valuable resource for students of liturgical time, the Cappadocians, and fourth-century doctrinal controversies.

Philip Schaff’s classic work colloquially known as The Early Church Fathers is an invaluable resource filled with the primary documents and early theological building blocks for the Christian church. Comprised of thirty-eight volumes, it is broken into three parts: the Ante-Nicene Fathers, and Nicene and Post-Nicene Fathers, First and Second Series.
