There are thousands who know little of the Catholic or of any other faith, and thousands who believe the Catholic Church to be everything except what it is. These people have no infallible rule of faith and morals, and when confronted, as they now are, by a dangerous, insidious campaign in favour of birth control, they do not react consistently or at all. It was therefore thought advisable to issue this statement in defence of the position of the Catholic Church; but the reader should remember that the teaching of the Church on this matter is held by her members to be true, not merely because it agrees with the notions of all right-thinking men and women, not because it is in harmony with economic, statistical, social, and biological truth, but principally because they know this teaching to be an authoritative declaration of the law of God. The Ten Commandments have their pragmatic justification; they make for the good of the race; but the Christian obeys them as expressions of the Divine Will. Section 5. CONCLUSION Our declining birth-rate is a fact of the utmost gravity, and a more serious position has never confronted the British people. Here in the midst of a great nation, at the end of a victorious war, the law of decline is working, and by that law the greatest empires in the world have perished. In comparison with that single fact all other dangers, be they of war, of politics, or of disease, are of little moment. Attempts have already been made to avert the consequences by the partial endowment of motherhood and by a saving of infant life. Physiologists are now seeking among the endocrinous glands and the vitamines for a substance to assist procreation. "Where are my children?" was the question shouted yesterday from the cinemas. "Let us have children, children at any price," will be the cry of to-morrow. And all these thoughts were once in the mind of Augustus, Emperor of the world from the Atlantic to the Euphrates, from Mount Atlas to the Danube and the Rhine. The Catholic Church has never taught that "an avalanche of children" should be brought into the world regardless of consequences. God is not mocked; as men sow, so shall they reap, and against a law of nature both the transient amelioration wrought by philanthropists and the subtle expediences of scientific politicians are alike futile. If our civilisation is to survive we must abandon those ideals that lead to decline. There is only one civilisation immune from decay, and that civilisation endures on the practical eugenics once taught by a united Christendom and now expounded almost solely by the Catholic Church.
