So God created man in his own image, in the image of God he created him; male and female he created them. And God blessed them, and God said to them, "Be fruitful and multiply, and fill the earth and subdue it; and have dominion over the fish of the sea and over the birds of the air and over every living thing that moves upon the earth."
The basic good of Marriage are union and fruitfulness: union between husband and wife and fruitfulness–both physical and spiritual–in the womb and the soul. This requires what the Christian life requires: faith, hope, and love, three items we cannot muster without the help of God. Faith means "you stay." Hope means "God is taking you someplace wonderful.' And love means you desire and labor toward that Day when your neighbor has all the graces of God you want for yourself and those you love most. The family is the training ground for these virtues. The goods and requirements are, by God's clever design, the same thing. To have faith you must be faithful; to have hope, you must hope; to have love, you must love. Today, seek to live in faith, hope, and love in your family. If you cannot love your family whom you have seen, you cannot love Humanity, whom you have not seen.
