No political view will “get anyone to Heaven”.
However, there is a very serious difficulty with attempting to hold modern liberalism and Christianity: modern liberalism is one of that genus of ideology that essentially denies the Fall and fancies that man is perfectible in this world by worldly measures. In liberalism’s world there is no need of grace, just proper social engineering, social engineering that inevitably rejects the wisdom of ages found in the moral teachings of the Torah, the words of Our Lord, the letters of the Holy Apostle Paul, and the writings of the Church Fathers. To be a modern liberal and a Christian requires a sort of double-mindedness that Our Lord and His Apostles very much rejected.
Certainly some tendencies on the American right — for example, the atomism of Randian libertarianism or the extension of proper contempt for state-run social programs into contempt for the poor — are as anti-Christian as anything found on the left. But the core tradition of not just American, but Anglo-American conservatism (from Burke to Lord Acton to Russell Kirk and William F. Buckley, Jr.) is self-consciously Christian and holds views of society and human nature, which even when worldly-colored are far closer to those found in the Scriptures and tradition of the Church than is “liberalism”.
“Liberalism” is simply the political expression of the religion of Humanism, which began with the lie “you will be as gods, knowing good and evil.”
It will continue to be an influence in this world until its author is banished to the pit forever.
I have always saved Elliot’s analysis on my home page:
“The world is trying the experiment of attempting to form a civilized but non-Christian mentality. The experiment will fail; but we must be very patient in awaiting its collapse; meanwhile redeeming the time; so that the Faith may be preserved alive through the dark ages before us; to renew and rebuild civilization, and to save the world from suicide.”
T.S. Eliot, Christianity and Culture
I agree. I have also read many of your comments in the past and often find myself enlightened by them. Keep using your gift.
My point is not to agree with liberal theology but to point out that true believers have the capacity to be deceived by it as much as other lies. This will harm them and others, but it is still not the litmus test for what makes someone a believer or not.
