Bible teacher Keith Dorricott surveys 2,000 years of Christianity and church history and explains how the important pattern that was set out in the New Testament in the early church as to how God wanted to be served, was gradually lost over the succeeding centuries.  He goes on to discuss how the understanding of the New Testament pattern, described by the apostle Jude as "the faith", was gradually recovered through the Reformation and the emergence of the Brethren movement, culminating in the re-establishment of Churches of God in the late nineteenth century.
