St. Paul is undoubtedly the most humanly interesting of the early followers of Christ precisely because he was so obviously human and thus prone to human faults, enthusiasms, and indignations. Furthermore, he preserved these every-day characteristics so vividly in his writings that not even the most avid hagiographers have been able to disguise that humanity. It is this intriguing individual whose mind and soul Father Cerfaux so ably explores in this book, by means of a detailed examination of Paul's copious correspondence. The narrative runs from the birth of the Church at the resurrection of Christ (c. 30) to the death of Paul at Rome (c. 67), and covers not only Paul's ""spiritual life"" (as the title may imply) but all of his activities and thought as he progressed along the roads that led from the East to Macedonia, Corinth, Asia Minor, and, finally, Rome. Basically, this is a scholarly work, but it is a surprisingly engaging and well written one that will prove useful not only to the scholar but also to the layman, and interesting to the historian as well as to the theologian.
