This classic defence of orthodox Christianity, written to counter the liberalism that arose in the early 1900s, establishes the importance of scriptural doctrine and contrasts the teachings of liberalism and orthodoxy on God and man, the Bible, Christ, salvation and the church.
"An admirable book. For its acumen, for its saliency, and for its wit, this cool and stringent defence of orthodox Protestantism is, I think, the best popular argument produced [in the controversy between Christianity and liberalism]."
- Walter Lippmann in A Preface to Morals
"It is my conviction that Machen's book can still speak today... Even for those who do not agree with his central thesis, Christianity and Liberalism can still be understood as representing one of the literary artifacts of a generation that had come to see liberalism as leading inexorably to a sentimentalized religion that had nothing to do with the God of the Bible or, indeed, with real life."
