The Reformation doctrine of vocation teaches that even seemingly secular jobs and earthly relationships are spheres where God assigns Christians to live out their faith, notes Gene Veith. But are there some lines of work that Christians should avoid?
God himself works through human vocations in providential care as he governs the world. He provides daily bread through farmers and bakers. He protects us through lawful magistrates. He heals us by means of physicians, nurses, and pharmacists. He creates new life through mothers and fathers. So we can ask whether or not God extends blessings through a particular line of work.
The purpose of every vocation, in all of the different spheres in which our multiple vocations occur—the family, the workplace, the culture, and the church—is to love and serve our neighbors. Loving God and loving our neighbors sums up our purpose (Matthew 22:36-40). Having been reconciled to God through Christ, we are then sent by God into the world to love and serve him by loving and serving our neighbors. This happens in vocation. So we can ask of every kind of work we doing, “Am I loving and serving my neighbor, or am I exploiting and tempting him?”
Obviously, those who make their living by robbery are not loving their neighbors. Heroin dealers, hit men, con artists, and other criminals are hurting their neighbors and have no calling from God to do so.
But there are some legal professions that also involve harming their neighbors instead of loving and serving them. An abortionist kills his small neighbor in the womb. An internet pornographer is abusing the neighbors he is exploiting sexually and, moreover, causing the neighbors who are his customers to sin.
Other occupations may not be so cut and dry.
