History of Dogma - Volume I

The most difficult part of the history of dogma is the beginning, not only because it contains the germs of all later developments, and therefore an error in observation here endangers the correctness of the whole following account, but also because the selection of the most important material from the history of primitive Christianity and biblical theology is a hard problem. Some will think that I have admitted too much into the book, others too little. Perhaps both are right. I can only reply that after repeated consideration and experiment I continue to be satisfied with my selection.
