18 For one thing, it is taught among us with regard to those who desire to marry that all those who are not suited for celibacy have the power, right, and authority to marry, for vows cannot nullify God’s order and command. 19 God’s command in 1 Cor. 7:2 reads, “Because of the temptation to immorality, each man should have his own wife and each woman her own husband.” 20 It is not alone God’s command that urges, drives, and compels us to do this, but God’s creation and order also direct all to marriage who are not endowed with the gift of virginity by a special act of God. This appears from God’s own words in Gen. 2:18, “It is not good that the man should be alone; I will make him a helper fit for him.”
