This review is from: Early Christian Doctrines: Revised Edition (Paperback)
Kelly presents a masterful summary of Church theology and history. This is a great price for the content. If you have even the slightest interest in the early Church, this book will serve to both satisfy your initial curiosities and spark new ones.
Other books of interst include Jaroslav Pelikan's "The Emergence of the Catholic Tradition (100-600)" and "Christianity and Classical Culture", both of which are technical. Georges Florovsky's works, most of which are out of print, are essential to understanding the Eastern Orthodox patristic tradition. "Aspects of Church History" by G.Florovsky is excellent, although the scope of the work isn't comparable to Kelly's. Meyendorff's "Christ in Eastern Christian Thought" is remarkable in depth, detail, and insight. Leo Donald Davis' "The First Seven Ecumenical Councils (325-787)" is the best in English on the subject of the coucils. Of course, the four volume "Patrology", by Johannes Quasten, is great for beginners and experts (so experts tell me!). A popular account of heresy in the early Church is C. FitzSimons Allison's "The Cruelty of Heresy: An Affirmation of Christian Orthodoxy". "Beginning to Read the Fathers" by Ramsey is also organized and useful. Enjoy!
