“Why did early Christianity alight on the ideal of virginity, when an intelligent or even just a suspicious Roman could see that its adoption would undermine the very fabric of ancient society?” That’s a comment from historian Kate Cooper and it poses some questions worth examining.

Does the single state, celibacy, (vowed or otherwise) undermine something inside the fabric of society? Is it somehow a statement against marriage? Does it go against something within nature itself where there is an innate imperative to “increase and multiply”?

The latter question is easier to answer. The human race has now exceeded eight billion. There is much less need to ensure that there are enough people in the world to ensure our biological survival. In former times, indeed in biblical times, there was a strong, quasi-sacred imperative that people marry and have children. Remaining unmarried was looked upon negatively, as an abnormality. Nature is not being honored or fulfilled here. Why is this person not doing his or her duty in terms of having children? That’s one of the reasons why Jesus’ choice of celibacy stands out as something abnormal in his world.

Next, does single life, celibacy, somehow speak against marriage? Does it, simply by definition, undermine the fabric of society? Doesn’t God, at the creation of the human race, pronounce that it is not good for the human person to be alone?

That question deserves more than a hurried answer. God did say this, and God meant it. We are meant to live inside family, in community, and not live alone. Thus, the single life has its dangers. Thomas Merton was once asked by a journalist what it was like to live as a celibate. His answer: It’s hell. You live in a loneliness that God Himself condemned. But, then he quickly added that this was a loneliness that could be very fruitful.

Still the question remains, is the single life, celibacy, somehow a statement against marriage? It can be. Choosing not to be married can be a statement that marriage isn’t the best way to live, that it is a container (a prison) which unhealthily restricts human freedom and human maturity. Single life in that instance (which is then often far from celibate) is a statement against marriage.

Healthy marriage and healthy single life in fact support each other. There’s an axiom which says: If you are here faithfully, you bring us health and support. If you are here unfaithfully, you bring us restlessness and chaos.

Fidelity in either marriage or in celibacy is a marathon with temptations of every kind along the way. It demands the capacity to sweat blood at times to remain faithful to what you have promised and to what is best in you. But it needs the support and witness of others. In neither vocation are you meant to go it alone, to be the lonely, stoic, ascetic hero. You are meant instead to be buoyed up and held by the support and faithful witness of others.

Thus, when a celibate sees fidelity being lived out inside a marriage, it becomes easier for him or her to remain faithful inside celibacy. Conversely, when a celibate sees infidelity inside of a marriage, he or she feels more isolated and alone inside celibacy and lacks a certain grace (which comes through witness) to sweat blood in terms of being faithful inside of celibacy.

The same dynamic holds true for a married person. If he or she sees a celibate faithfully and fruitfully living inside the single life, he or she is graced through that witness to find both some insight and strength to be true to his or her commitment. Conversely, if a married person sees a celibate living unfaithfully, he or she will lack a special grace that comes from witnessing fidelity which can help him or her sweat the blood that is sometimes required in order to remain faithful in a commitment.

As curious as this may sound, Marriage and Celibacy need each other. We need each other’s witness. We need to see, and feed off, each other’s fidelity.

And that’s true beyond just seeing each other being faithful. There’s a deeper reality undergirding this, a mystical one. As Christians, we believe that we are all part of one body, the Body of Christ, and that our unity there is not simply a corporate one (one team). Rather we are an organic unity, all part of one living organism. Hence, what one part does affects all the parts. If we are faithful, we are a healthy part of the immune system inside the Body of Christ. If we are unfaithful, in either marriage or celibacy, we are an unhealthy virus, a cancer cell, inside the body.

For Christians, there is no such a thing as a private act. We are either a healthy enzyme or an unhealthy virus inside a single body, where our fidelity or infidelity affects everyone else.

And so, we need each other’s fidelity – in marriage and in celibacy.
