Question Submitted: At a recent theological symposium, I posited that we in the Church need “to return to teaching properly about the positive locus of marriage – teaching about its procreative purpose and nature.” Another attendee replied in part that “procreation is NOT an intrinsic quality of marriage, as we do not say the infertile are not married.” If I had had a chance for rebuttal, I would have pointed out the error of his logic. Bipedalism is an intrinsic quality of humans, despite the sad reality of paraplegia. It would be very helpful to hear how you would counter the idea that infertility invalidates the argument that procreation is an intrinsic quality of marriage. I have my own answers to this false argument, but I would like to make sure I have an answer that is sensitive to the minds of those who suffer from infertility.
My pastors taught me that God institutes and defines marriage in Genesis Chapters 1 and 2. We learn in verses 1:27-28 that God created man in His own image; male and female He created them, and He blessed them. He told them to be fruitful and multiply, and God saw that “it was very good” (Gen 1:31).
The gift of procreation is not only a blessing God speaks over marriage, but God sees the blessing of children as good.
Barrenness is not good. Barrenness is a brokenness of God’s good creation. Endometriosis, PCOS, fibroids, hashimoto’s thyroiditis, low sperm motility, ovarian and cervical cancers, miscarriages, childlessness, and the groaning of all creation came about as a result of man’s fall into Sin; and we don’t use the effects of Sin to redefine that which God institutes and calls “good” in His Word, nor do we use the effects of Sin to defend the notion that procreation is somehow not a part of God’s intrinsic design of marriage. That is my biggest qualm with the other attendee’s rhetoric. His thesis does not fully confess barrenness as a post-Fall reality. Barrenness proves nothing about God’s procreative intent for marriage other than that God, post-Fall, allows the cross of barrenness to burden the shoulders of some married couples.
In regards to being sensitive to the barren, we should be careful not to turn God’s good, fruitful blessing for marriage into man’s good work. Scripture tells us that having children is not a law of God for us to keep but a heritage from Him for us to receive (Psalm 127:3). None of us would have children apart from God’s merciful blessing and giving. Only God in His wisdom knows why He does not open the wombs of the barren, and we should not burden the consciences of those who are unable to have children by suggesting they should be able to outwit the very Author of Life.
And as for using the existence of barrenness as an excuse to avoid the gift of children in marriage, I can think of no place in Scripture where God calls that good.
