In the past I have appreciated Dr. Carl Trueman’s teaching on Medieval theology and also the Reformation available through Itunes University. He’s also written a more practical book on the Reformation for today for the general Christian readers titled Reformation: Yesterday, Today and Tomorrow by Carl Trueman.
Every year The Master Seminary brings in a scholar to teach for the Winterim and for this year (2017) they have Dr. Trueman of Westminster Theological Seminary taught on the history of the Reformation.
The entire 19 lectures in video form have been made available online for free!
Enjoy!
