Most historical theology studies follow Christian beliefs chronologically, discussing notable doctrinal developments for all areas of theology according to their historical appearance. While this may be good history, it can make for confusing theology, with the classic theological doctrines scattered throughout various time periods, movements, and controversies.
In Historical Theology Video Lectures and its accompanying textbook, Gregg Allison offers students the opportunity to study the historical development of theology by a topical-chronological arrangement, setting out the history one doctrine at a time. This approach allows students to concentrate on one tenet of Christianity and its formulation in the early church, through the Middle Ages, Reformation, and post-Reformation era, and into the modern period.
Historical Theology Video Lectures is a superb resource for students and self-learners wanting to better understand the development of Christian theology.
