I just finished reading a Christian classic, Christianity and Liberalism by J. Gresham Machen. It was written in 1923 in response to the liberal threat to Christianity. The liberal element of Christianity was denying doctrines such as the inerrancy of the Bible, the deity of Jesus Christ, the exclusivity of the gospel and the nature of the atonement. Machen forcefully argues that liberal Christianity, with its denial of these foundational doctrines, is not Christianity at all. Although written in 1923 it reads as though it were written today. Every doctrine that was challenged in 1923 is being challenged now. The only difference is that instead of veiled objections, the opponents of Christianity boldly voice their objections to Christianity. I highly recommend this book, it is now on my top ten list of books that every Christian should read.
