"For openers, marriage is neither a matter of politics, nor is it a matter of social policy. Marriage is defined by the Lord Himself. It's the one institution that is ceremoniously performed by priesthood authority in the temple [and] transcends this world. It is of such profound importance... such a core doctrine of the Gospel of Jesus Christ, of the very purpose of the creation of this earth. One hardly can get past the first page of Genesis without seeing that very clearly."
