This is a breath of fresh air. You could substitute many of the names of Kähler’s late-nineteenth-century contemporaries for those of modern scholars like Bart Ehrman, Dominic Crossan, etc. and the book would read as though it were written for today.
Amidst the stifling views of both biblical inerrantists and historical critics (largely of the Jesus Seminar) on each extreme, Kähler offers a way forward that recognizes and appreciates the Word of God contained in the biblical texts and their overall kerygmatic and Christocentric purpose (rather than viewing them as texts designed for modern (and anachronistic) historical biographical accounts).
