Series by Harrison Perkins

The early post-apostolic church followed the biblical pattern by articulating the “rule of faith” (regula fidei), which became the basis for the Apostles’ Creed, which, through not written by the Apostles’ themselves, was and is received as a summary of the doctrine of the apostles. We find Irenaeus (c. AD 130–202), the pastor of Lyons, articulating the regula fidei as early as the AD 170s. Tertullian (c. AD 155–c.220), the father of North African theology and hence Western or Latin theology, also articulated the regula fidei. The Apostles’ Creed was substantially complete by the mid-fourth century.
