All existing efforts which tend to destroy the causes of licentiousness--such as temperance, increase of occupation and wages for women, improvement of poor dwellings, facilities for rational amusement, the abolition of enforced celibacy, and the regeneration of the army--demand and should receive the special recognition and aid of parents. These movements are all invaluable and cannot be too actively supported, being founded on true principles of growth; but something more is needed--viz., distinct open acknowledgment of the fundamental principle here laid down, and organization growing out of it. In this work the natural leader of a nation is the Church--_i.e._, that great body of all religious teachers and persons who believe that man cannot live by bread alone, but that the Divine instinct that urges him onwards and upwards must be expressed in the forms of our daily life. When the Church recognises that one of its difficult but glorious duties is to teach men how to carry out religious principles in practical life, it will perceive that the foundation of all righteous life is reverence for the noble human principle of sex. It will no longer shrink from enforcing this regenerating principle. The undue proportion of thought and effort now given to forms and ceremonies, to metaphysical disquisitions and subtle distinctions, will then give place to earnest united efforts to enable men to lead righteous lives. No Church performs its duty to the young that fails to raise this fundamental subject of sex into its proper human level. It is bound to rouse every young man and woman of its congregation to the perception that respect for the principle of sex, with fidelity to purity, is a fundamental condition of religious life. The truths which have been set forth in the preceding pages may be briefly summed up in the following propositions--viz: Early chastity strengthens the physical nature, creates force of Will, and concentrates the intellectual powers on the nobler ends of human life. Continence is indispensable to the physical welfare of a young man until the age of twenty-one; it is advantageous until twenty-five; it is possible without physical injury throughout life. The passion of sex can only be safely and healthily gratified by marriage; illegal relations produce physical danger, mental degradation, and social misery. The family is the indispensable foundation of a progressive nation, and the permanent union of one man with one woman is essential to the welfare of the family. Marriage during matured early vigour is essential to the production of a strong race. Individual morality can only be secured by the prevalence of early purity, and national morality by the cumulative effects of heredity. In Moral Education the first step to secure is the slow development of sex; the second, its legitimate satisfaction through honourable companionship, followed by marriage.
