“Jesus, the Apostles, and the Early Church”, “St. Paul”, and “The Church Fathers: From Clement of Rome to Augustine” are all based on a sermon series given on Wednesdays over a several month period. Each chapter is only 5-8 pages long, since it is based on a sermon, but it makes for an easy, but theologically rich and informative read. These three books make a sort of trilogy together that takes one through a large number of the important figures of the early Church. (These books would fit VERY WELL after reading “Jesus of Nazareth” first!)
There are two versions of each of these books, one by Ignatius Press, and one by Our Daily Visitor. They are almost identical, but the Ignatius Press books seem to be printed on much higher quality paper and with a better binding. (“The Apostles” is the Our Daily Visitor version of “Jesus, the Apostles, and the Early Church”, and “The Fathers” is the Our Daily Visitor version of “The Church Fathers: From Clement of Rome to Augustine”)
