I read Casti Connubii today, Pius XI’s great encyclical on marriage. I have taken a very great interest in questions of marriage – its importance in society, its interior ethics, and various connected questions. Something I have been adamant about for a while has been that a good marriage preparation course will stress that the point of matrimony, as the sacramental elevation of marriage by Christ, is not merely to have children in the safe bounds of wedlock – it is in fact to offer an incalculable gift to God… A soul which will worship Him forever in Heaven. It is an act of religion.

Pius XI agrees. Here he speaks:

12. How great a boon of God this is, and how great a blessing of matrimony is clear from a consideration of man’s dignity and of his sublime end. For man surpasses all other visible creatures by the superiority of his rational nature alone. Besides, God wishes men to be born not only that they should live and fill the earth, but much more that they may be worshippers of God, that they may know Him and love Him and finally enjoy Him for ever in heaven; and this end, since man is raised by God in a marvelous way to the supernatural order, surpasses all that eye hath seen, and ear heard, and all that hath entered into the heart of man. From which it is easily seen how great a gift of divine goodness and how remarkable a fruit of marriage are children born by the omnipotent power of God through the cooperation of those bound in wedlock.

13. But Christian parents must also understand that they are destined not only to propagate and preserve the human race on earth, indeed not only to educate any kind of worshippers of the true God, but children who are to become members of the Church of Christ, to raise up fellow-citizens of the Saints, and members of God’s household, that the worshippers of God and Our Savior may daily increase.

14. For although Christian spouses even if sanctified themselves cannot transmit sanctification to their progeny, nay, although the very natural process of generating life has become the way of death by which original sin is passed on to posterity, nevertheless, they share to some extent in the blessings of that primeval marriage of Paradise, since it is theirs to offer their offspring to the Church in order that by this most fruitful Mother of the children of God they may be regenerated through the laver of Baptism unto supernatural justice and finally be made living members of Christ, partakers of immortal life, and heirs of that eternal glory to which we all aspire from our inmost heart.

15. If a true Christian mother weigh well these things, she will indeed understand with a sense of deep consolation that of her the words of Our Savior were spoken: “A woman . . . when she hath brought forth the child remembereth no more the anguish, for joy that a man is born into the world”; and proving herself superior to all the pains and cares and solicitudes of her maternal office with a more just and holy joy than that of the Roman matron, the mother of the Gracchi, she will rejoice in the Lord crowned as it were with the glory of her offspring. Both husband and wife, however, receiving these children with joy and gratitude from the hand of God, will regard them as a talent committed to their charge by God, not only to be employed for their own advantage or for that of an earthly commonwealth, but to be restored to God with interest on the day of reckoning.
