The first decade of the fourth century, from about 302 to 313, is one of the most remarkable in history. In that short time, the Church would go from the worst of persecutions to the beginning of an unprecedented new era of peace and favor. In what we might consider a foreshadowing of the Church’s trials and final victory at the end of the world, the Great Persecution was merely the labor pains for the birth of Christendom.

This installment covers popes #29-32: Sts. Marcellinus, Marcellus I, Eusebius, and Miltiades.
