“The Bible’s teaching on marriage does not merely reflect the perspective of any one culture or time. The teachings of Scripture challenge our contemporary Western culture’s narrative of individual freedom as the only way to be happy. At the same time, it critiques how traditional cultures perceive the unmarried adult to be less than a fully formed human being. The book of Genesis radically critiques the institution of polygamy, even though it was the accepted cultural practice of the time, by vividly depicting the misery and havoc it plays in family relationships, and the pain it caused, especially for women. The New Testament writers, in a way that startled the pagan world, lifted up long-term singleness as a legitimate way to live. In other words, the Biblical authors’ teaching constantly challenged their own cultures’ beliefs – they were not simply a product of ancient mores and practices. We cannot, therefore, write off the Biblical view of marriage as one-dimensionally regressive or culturally obsolete. On the contrary, it is bristling with both practical, realistic insights and breathtaking promises about marriage.”
