Round the Sphere Again: Christian History

And Christology
James White recently did a seminary level lecture (2 1/2 hours long) on Christology. 

Christology should be a fundamental area of study of any serious believer, yet it is often an area of profound ignorance amongst many who name the name of Christ. We would like to help our listeners to have a much better grasp of this vital area. 

To that end, James White covers “such things as the Athanasian Creed, the Symbol of Chalcedon, Apollinarianism, Eutychianism, Nestorianism, etc.” To get the most from the lecture, do your homework first.

And Biography
Erik Raymond (Ordinary Pastor) lists a few recommended entry level Christian biographies.
