Russell Shaw Being legalistic and being law-abiding, and the big difference 

May 13, 2017

In case you didn't notice, Pope Francis thinks legalism is a bad thing – and that's good news. For legalism, correctly understood, is opposed to authentic morality.

The Pope returned to this theme, a favorite of his, in several recent homilies preached at his morning mass in the Casa Santa Maria, the Vatican guest house where he lives. In one, his special targets were the doctors of the law who tried to keep the apostles from preaching the risen Christ. For them, he said, the Word "was not made flesh – it was made law."

Over the centuries, he added, this same "rationalistic mentality" has often existed in the Church. As indeed it does today.

The Holy Father's critique needs to be taken very seriously. And that requires understanding what legalism is. 

To begin with, legalistic is not the same as law-abiding. To be law-abiding means obeying just laws – and even unjust ones, provided they do not require doing something wrong in itself, if disobeying would be too socially disruptive. But to be legalistic means – something else. What?

The first volume ("Christian Moral Principles") of The Way of the Lord Jesus, the three-volume magnum opus of the American moral theologian and ethicist Germain Grisez, provides a helpful answer to that question. (Disclosure: Grisez is a friend with whom I've collaborated on several books.) 

For various reasons, he explains, legalism was prevalent in moral theology from the 16th century Council of Trent up to Vatican Council II (1962-65). A legalist, he writes, "tends to think of moral norms as if they were merely a body of rules." One result of that, he says, can be seen in "the suggestion that the Church might or should change its moral teaching, as if it were changeable law rather than unchangeable truth."

Then came Vatican II, whose document on the training of priests calls for a reform of moral theology. Taught "in the light of faith, under the guidance of the magisterium of the Church," it says, moral theology should be more Christocentric, should "draw more fully on the teaching of holy Scripture" and should show the duty of Christians "to bring forth fruit in charity for the life of the world" (Optatam Totius, 16). 

Since the council, many theologians have worked hard at this. Some unfortunately have not. Instead, they have treated doctrines – the Church's teachings on matters of sexuality are a good example – as if they were rules, rather than understanding them as moral truths. On that basis, they have urged either changing the rules or else simply ignoring them in light of private discernment and, it seems, something akin to individual illumination by the Holy Spirit. 

It's a curious fact, as Grisez remarks, that this version of a new moral theology is in its own way "as legalistic as the old." Typically, it devotes much time and effort to "trying to lessen the obligations of Christian life….Doing as one pleases is then called 'following one's conscience.'"

The old legalism is a morality of young children, for whom being good means doing what parents and other authority figures tell them to do, while being bad means disobeying. Pope Francis aptly terms this "a theology of yes, you can [and] no, you can't." 

More recently, though, we've seen a morality of adolescence that frequently involves acting out against authority and operating by impulse and feeling. It's the flip side of childish morality. And in the end the new legalism is even more unsatisfactory than the old.
