"I think I understand how the typical Protestant feels...

... about sacramentalism not only because I was a Protestant but because it is a natural and universal feeling. The Catholic doctrine of the sacraments is shocking to everyone. It should be a shock to Catholics too. But familiarity breeds dullness.

To Protestants, sacraments must be one of two things: either mere symbols, reminders, like words; or else real magic. And the Catholic definition of a sacrament — a visible sign instituted by Christ to give grace, a sign that really effects what it symbolizes — sounds like magic. Catholic doctrine teaches that the sacraments work ex opere operato, i.e., objectively, though not impersonally and automatically like machines. They are gifts that come from without but must be freely received.

Protestants are usually much more comfortable with a merely symbolic view of sacraments, for their faith is primarily verbal, not sacramental. After all, it is the Bible that looms so large in the center of their horizon. They believe in creation and Incarnation and Resurrection only because they are in the Bible. The material events are surrounded by the holy words. The Catholic sensibility is the inside-out version of this: the words are surrounded by the holy facts. To the Catholic sensibility it is not primarily words but matter that is holy because God created it, incarnated himself in it, raised it from death, and took it to heaven with him in his ascension.

Orthodox Protestants believe these scriptural dogmas, of course, just as surely as Catholics do. But they do not, I think, feel the crude, even vulgar facticity of them as strongly. That's why they do not merely disagree with but are profoundly shocked by the real presence and transubstantiation. Luther, by the way, taught the real presence and something much closer to transubstantiation than most Protestants believe, namely consubstantiation, the belief that Christ's body and blood are really present in the Eucharist, but so are the bread and wine. Catholics believe the elements are changed; Lutherans believe they are added to.

Most Protestants believe the Eucharist only symbolizes Christ, though some, following Calvin, add that it is an occasion for special grace, a sign and a seal. But though I was a Calvinist for twenty one years, I do not remember any emphasis on that notion. Much more often, I heard the contrast between the Protestant " spiritual " interpretation and the Catholic "material ", "magical" one.

The basic objection Protestants have to sacramentalism is this: How can divine grace depend on matter, something passive and unfree? Isn't it unfair for God's grace to depend on anything other than his will and mine? I felt that objection strongly until I realized that the sheer fact that I have a body — this body, with this heredity, which came to me and still comes to me without my choice — is also "unfair". One gets a healthy body, another does not. As one philosopher said, "Life isn't fair."
