Abstract
The American philosopher George Santayana once proclaimed, "Those who do not remember the past are doomed to repeat it." Christians should especially be attentive to the important lessons from the past, for the truth-claims of Christianity (which center upon the life, death, and resurrection of Jesus Christ) stand rooted in the facts of history. Contemporary Christians can be enriched greatly by the careful study of Christendom's creeds and of the events that surrounded their formulation. The appropriate use of the creeds can, and do, enhance Christian education, worship, and evangelism. Additionally, an exploration of the ancient creeds can also reveal some important apologetic lessons for twenty-first century Christians.
