From Moral Man and Immoral Society:
Sentimentality is the peculiar vice of liberal Protestantism. By adjusting its faith to the spirit of modern culture it imbibed the evolutionary optimism and the romantic overestimates of human virtue, which characterized the though of the Enlightenment and of the Romantic Movement…
In spite of the disillusionment of the World War, the average liberal Protestant Christian is still convinced that the kingdom of God is gradually approaching, that the League of Nations is its partial fulfillment and the Kellogg Pact its covenant, that the wealthy will be persuaded by the church to dedicate their power and privilege to the common good and that they are doing so in increasing numbers, that the conversion of individuals is the only safe method of solving the social problem, and that such ethical weaknesses as religion still betrays are due to its theological obscurantism which will be sloughed off by the progress of the enlightenment.
