During services in Christian communities, the members of the congregation stand together to recite the creed, professing in unison the beliefs they share. For most Christians, the creed functions as a sort of "ABC" of what it means to be a Christian and to be part of a worldwide movement. Few people, however, know the source of this litany of beliefs, a topic that is further confused by the fact that there are two different versions: the Apostle's Creed and the Nicene Creed.

In The Creed, Luke Timothy Johnson, a New Testament scholar and Catholic theologian, clarifies the history of the creed, discussing its evolution from the first decades of the Christian Church to the present day. By connecting the deep theological conflicts of the early Church with the conflicts and questions facing Christians today, Johnson shows that faith is a dynamic process, not based on a static set of rules. Written in a clear, graceful style and appropriate for Christians of all denominations, The Creed is destined to become a classic of modern writings on spirituality.
