"I Believe", Exploring the Apostles' Creed by Alister McGrath, InterVarsity Press, 1991, 1997.  McGrath is principal of Wycliffe Hall, Oxford and research professor of theology at Regent College, Vancouver, BC.  His numerous books include Understanding Doctrine, A Passion for Truth, A Life of John Calvin, The Twilight of Atheism.  The discussion questions following each chapter make this book helpful for a small group study.  It is also useful for pastors preaching a series on the Apostles' Creed.

I Believe... The Apostles' Creed for the Third Millennium by Robert P. Mills, PLC Publications, 1998. "These studies begin with an introductory section on the nature of faith, the purpose of creeds, and the place of doubt. The remaining sections follow the order of the Creed and consider what the Creed has to teach about God the Father, God the Son, and God the Holy Spirit. Each chapter looks at a single article, or at times a single word, seeking to understand how the Creed is rooted in Scripture, how it has been understood throughout church history, and how it remains relevant.

The chapters conclude with questions for reflection and a suggested prayer for personal or corporate response. A list of Scripture passages for further study and additional resources are also included at the end of each chapter. The questions and Scripture readings make each chapter a suitable lesson for a Sunday School class, communicant’s class, or other group study. "
