Later Chrisitan writers felt it important to answer Julian the Apostate's criticisms of Chritianity in his book Against the Galileans. They quoted liberally from the book, and, partly because of their interest, we have substantial portions of a book that might otherwise have been lost.
The reign of Constantine is certainly an important turning point in the history of Rome and in the history of the church. Please read through the Edict of Milan (either the hard-copy I gave you, or the online edition here. Cite one line that particularly well shows a way in which Constantine changes things for the church.
Diocletian and Constantine attempted to solve, not only the political and social problems of Rome, but also fundamental economic problems as well. Bruce Bartlett argues that the two did exactly the wrong thing. Please read Bartlett's article How Excessive Government Killed Rome. Do you think Bartlett's criticisms accurate? Why, or why not?
Many Romans of the imperial period followed Virgil, Ovid, and Horace in hoping for a political leader who would solve Rome's problems. At the same time, many other Romans were looking to an entirely different hope. The Gospel of Luke is particularly good at describing that hope. Please read through a chapter or two of Luke's gospel, and pick out a verse that might have had particular appeal to those living under the rule of Imperial Rome.
Herodian of Antioch's History of the Roman Empire is an important source for the AD 180-238 period. Choose one of the emperors from this period (possibilities include Commodus, Pertinax, Didius Julianus, Septimius Severus, Macrinus, Bassianus, and Alexander Severus) and note what Herodian has to say about that emperor. Cite here an example of that emperor's competence (or lack thereof) and an example of the difficulties that emperor faced, looking especially for problems that emperor had with the Roman army.
Plato said that, in an ideal society, the philosophers would be the kings, or the kings would be philosophers. Marcus Aurelius in some ways would seem to be exactly the kind of "philosopher emperor" Plato would have wanted. Please read the opening sections of Marcus Aurelius' Meditations. Choose a line that particularly well shows one of the things Aurelius particularly values, and note whether this value would make him a good emperor or not.
