Liberalism as a Christian Heresy

Russ Douthat:

[T]he more purely secular liberalism has become, the more it has spent down its Christian inheritance—the more its ideals seem to hang from what Christopher Hitchens’ Calvinist sparring partner Douglas Wilson has called intellectual “skyhooks,” suspended halfway between our earth and the heaven on which many liberals have long since given up. Say what you will about the prosperity gospel and the cult of the God Within and the other theologies I criticize in Bad Religion, but at least they have a metaphysically coherent picture of the universe to justify their claims. Whereas much of today’s liberalism expects me to respect its moral fervor even as it denies the revelation that once justified that fervor in the first place. It insists that it is a purely secular and scientific enterprise even as it grounds its politics in metaphysical claims. (You will not find the principle of absolute human equality in evolutionary theory, or universal human rights anywhere in physics.) It complains that Christian teachings on homosexuality do violence to gay people’s equal dignity — but if the world is just matter in motion, whence comes this dignity? What justifies and sustains it? Why should I grant it such intense, almost supernatural respect?
