Let's talk about what it means to really be married and the significance in Law.

MAR'RIAGE, n. The act of uniting a man and woman FOR LIFE; wedLOCK; the legal union of a man and woman FOR LIFE. Marriage is a covenant both civil and religious, by which the parties engage to live together in mutual affection and fidelity, TILL DEATH shall separate them. (Webster's 1828 Dictionary) 

 

PRO' FANE, v.t. TO VIOLATE ANY THING SACRED, or any ordinance of God (such as marriage). To treat it with abuse, irreverence or contempt. To put to a wrong use. 

DIVORCE, v.t. TO DISSOLVE the marriage contract, and thus to separate husband and wife. To separate, as a married woman from the bed and board of her husband. To force ASUNDER. To take away; to put away; to part. 

...they are no more twain, but one flesh. What therefore God hath joined together, let NOT man put ASUNDER. Matthew 19:6
