Marriage is an institution established by God long before government came along and government had no right to change it. Marriage is established not just to serve the needs of adults but more importantly to provide a stable, secure, nurturing environment in which to raise children. A man and a woman complement each other and care for children from their unique perspectives and a child needs both and ideally should be able to nurtured by both. We can pretend that gender does not matter in marriage but that does not reflect reality from the child’s standpoint. The government, which has a goal of preserving a stable society, has an interest in promoting the best marriage arrangement in which children should be raised and one man-one woman marriage is that model and is the only one government should recognize.
