Ten Principles on Marriage and the Public Good

1. Marriage is a personal union, intended for the whole of life, of husband and wife.
2. Marriage is a profound human good, elevating and perfecting our social and sexual nature.
3. Ordinarily, both men and women who marry are better off as a result.
4. Marriage protects and promotes the wellbeing of children.
5. Marriage sustains civil society and promotes the common good.
6. Marriage is a wealth-creating institution, increasing human and social capital.
7. When marriage weakens, the equality gap widens, as children suffer from the disadvantages of growing up in homes without committed mothers and fathers.
8. A functioning marriage culture serves to protect political liberty and foster limited government.
9. The laws that govern marriage matter significantly.
10. "Civil marriage" and "religious marriage" cannot be rigidly or completely divorced from one another.
