While this book is over a hundred years old, there is a wealth of information packed in here. Comprised of oral lectures given by Scotch presbyerian theologian James Orr, he retraces the history of dogma in a chronological way, highlighting the important epochs from the early fathers all the way up to, what was then at the turn of the 20th century, the beginning of modernity and the head on colision theology would have with science and darwinism. Some figures he spends a lot of time with, such as the early formative periods of the ecumenical councils, whereas other figures he barely brushes such as Böhme or Schleiermacher. All in all a great read. I am gearing up to read Adolf Von Harnack's "History of Dogma" in seven volumes.
