The two best sources of Church history that I have come across are Foxes book of martyrs and The lamp in the dark trilogy.
The lamp in the dark Triology
The lamp in the dark trilogy is made out of three movies
1. A Lamp in the Dark: The Untold History of the Bible
2. Bridge to Babylon: Rome, Ecumenism & the Bible
3. Tares Among the Wheat: Sequel to A Lamp in the Dark
