God in the Garden of Eden performed the first marriage. Adam and Eve, both made in God 's image, were joined together by God and commanded to "be fruitful and multiply, and replenish the earth" (Genesis 1).

The biblical concept of marriage is an oneness between two individuals that pictures the oneness of Christ with His church. God intended husband and wife to be a spiritual, functional unity, walking in integrity, serving God, and keeping His commandments together. When this harmony is operative, society prospers under God’s hand. The requirements of marriage are for one man and one woman to be married to each other. Not same sex marrying the same sex.
