Marriage, the relationship of husband and wife, a faithful union, marks the first human compact. The earliest recognized distinction between that which is lawful and that which is unlawful found its expression in marriage. In some places the old names for "law" and "marriage" are interchangeable. Whatever ceremonies may have accompanied it, however some (at all times) have evaded its obligation, the primæval conscience, the original human instinct, before the formation of any Church or code, recognized the need of a "covenant" first in marriage. Around it laws have grown. It is no invention of legislators. It arose from the divinely implanted necessities of "human" life, and a sense of its excellence above that of other animals "which have no understanding." Thus marriage grew to be called an "honourable estate;" to be surrounded with ceremony and fenced with safeguards.
