Machen on Religion and its "Usefulness"

Though these words by J. Gresham Machen are dated and some of the players have changed (i.e. the liberal church in the U.S. of the 1920s, though similar, is very different today), I believe them to still be significant to today's social environment in the U.S. Nationalism can come in many forms.

It can be said reverently that the Christian longs for heaven not only for his own sake, but also for the sake of God. Our present love is so cold, our present service so weak; and we would one day love and serve Him as His love deserves. It is perfectly true that the Christian is dissatisfied with the present world, but it is a holy dissatisfaction; it is that hunger and thirst after righteousness which our Savior blessed. We are separated from the Savior now by the veil of sense and by the effects of sin, and it is not selfish to long to see Him face to face. To relinquish such longing is not unselfishness, but is like the cold heartlessness of a man who could part from father or mother or wife or child without a pang. It is not selfish to long for the One whom not having seen we love.

Such is the Christian life--it is a life of conflict but it is also a life of hope. It views this world under the aspect of eternity; the fashion of this world passeth away, and all must stand before the judgment seat of Christ.

Very different is the "program" of the modern liberal Church. In that program, heaven has little place, and this world is really all in all. The rejection of the Christian hope is not always definite or conscious; sometimes the liberal preacher tries to maintain a belief in the immortality of the soul. But the real basis of the belief in immortality has been given up by the rejection of the New Testament account of the resurrection of Christ.

And, practically, the liberal preacher has very little to say about the other world. This world is really the center of all his thoughts; religion itself, and even God, are made merely a means for the betterment of conditions upon this earth.

Thus religion has become a mere function of the community or of the state. So it is looked upon by the men of the present day. Even hard-headed business men and politicians have become convinced that religion is needed. But it is thought to be needed merely as a means to an end. We have tried to get along without religion, it is said, but the experiment was a failure, and now religion must be called in to help.

For example, there is the problem of the immigrants; great populations have found a place in our country; they do not speak our language or know our customs; and we do not know what to do with them. We have attacked them by oppressive legislation or proposals of legislation, but such measures have not been altogether effective.

Somehow these people display a perverse attachment to the language that they learned at their mother's knee. It may be strange that a man should love the language that he learned at his mother's knee, but these people do love it, and we are perplexed in our efforts to produce a unified American people. So religion is called in to help; we are inclined to proceed against the immigrants now with a Bible in one hand and a club in the other offering them the blessings of liberty. That is what is sometimes meant by "Christian Americanization."
