This unit explores the development of theology within the early church that have been seminal for later generations. The theological themes investigated include the unity and diversity in the faith of the early Christian communities, the tension between charismatic and institutional forms of ministry and authority, the Trinitarian and Christological debates within the church, and the Donatist and Pelagian disputes. It aims to help students appreciate the distinctive flavour of early Christian texts, and to understand both the questions which led to the classic formulations of Christian doctrine and the shape and limitations of those answers.
