In his brief anthology of blog posts entitled, There are Two Marriages: A Manifesto on Marriage (2011), Tony Jones argues that the church ought to seek the strict separation of what he calls “legal marriage” and “sacramental marriage.” A result of this change would be the removal of much of the church’s resistance to same sex marriage.
Yesterday I rehearsed Jones’s historical and theological objections to the connivance of state and in marriage. I will argue today that Jones fails to recognize that marriage is, for the Christian, necessarily the union of religious belief with the physical world:
….Marriage matters because we are embodied and what we do with our body matters.
The church has affirmed over the centuries—almost with no exception—that marriage exists not only for the mutual aid and comfort of husband and wife, but also for the procreation of children.
“The union of husband and wife in heart, body, and mind is intended by God for their mutual joy; for the help and comfort given one another in prosperity and adversity; and, when it is God’s will, for the procreation of children and their nurture in the knowledge and love of the Lord. Therefore marriage is not to be entered into unadvisedly or lightly, but reverently, deliberately, and in accordance with the purposes for which it was instituted by God.”
We’d likely all agree that a marriage may be legitimate without children being born to the couple—having children does not a marriage make. However, it is a relatively recent innovation to believe that childbearing and marriage are totally unrelated.
Jones seeks to trace the changing nature of matrimony as grounds for a continued development of marriage to include same-sex couples. For example, in the ancient world marriage was simply the exchange of property with the consequent production of progeny.
Today marriage has become simply, “formalizing and cementing a romantic attraction.” It is emphatically not about having children. If it were, we would not allow “celibate, infertile, post-menopausal, non-producing” people to be legally married.
The reference is to restrictions on marriage, principally state laws that forbid consanguinity but that fail to forbid marriage between people unable to conceive. To derive a mandate for the church simply by the absence of state law on the matter is not a terribly good way to do affirmative theology.
As a pastor, were a couple to ask me to marry them and state up front that they would not be sexually intimate with one another nor would they even consider attempting to conceive, I would likely not marry them. Marriage is intrinsically linked with both sexual intimacy and with procreation. That some are unable to conceive doesn’t invalidate the rule, rather it’s the exception that proves it.
In all, Jones fails to build a compelling case for changing the nature and definition of marriage either in the state or in the church. He assumes that since people will always be gay—which is true—we should incentivize gay monogamy in the context of marriage. On the surface this may appear sound. However, Jones’s contention fails to consider that in the Christian view it is not simply that homosexual polyamory is wrong, but that all homosexual practice is not only inconsistent with Christian holiness, and is detrimental to human wholeness. To change marriage means more than “live and let live,” it necessarily encourages destructive behavior and, moreover, will inevitably lead to restrictions on religious groups that fail to recognize the appropriateness of same sex marriage.
