What is a covenant marriage? A covenant is defined as an agreement, a promise, a pledge—usually formal—between two or more people to do or not do something specified. Marriage between a man and a woman is a type of covenant. In a marriage covenant, the ultimate authority is God, not a judge. A minister or a judge may perform the ceremony, but the vows or pledges made in a marriage ceremony are to the LORD first, then to each spouse. This covenant is to be a lifelong agreement that only death dissolves. “So then, they are no longer two but one flesh. Therefore what God has joined together, let no man separate” (Matthew 19:6).
