Early Christian Doctrine is a clear, precise and up-to-date account of the early history of Christian doctrine. It is invaluable for an understanding of the formative period when the main lines of Christian dogma were laid down; and it presents a balanced picture of the early controversies in the light of modern scholarship. The doctrines of the Trinity, the authority of the Bible and tradition, the nature of Christ, salvation, original sin and grace, and the sacraments are all extensively treated in these pages.
