I don't know a lot of authors of that era, but I am a fan of George MacDonald (as was C.S. Lewis). He wrote a collection of essays called "Unspoken Sermons" that is quite good, but mostly he communicated his theology through writing novels. A lot of the things he had to say about nineteenth century Scotland apply just as well to a twenty-first century American audience.
