Certainly moral theology and its teaching are meeting with particular difficulty today. Because the Church’s morality necessarily involves a normative dimension, moral theology cannot be reduced to a body of knowledge worked out purely in the context of the so-called behavioural sciences. The latter are concerned with the phenomenon of morality as a historical and social fact; moral theology, however, while needing to make use of the behavioural and natural sciences, does not rely on the results of formal empirical observation or phenomenological understanding alone. Indeed, the relevance of the behavioural sciences for moral theology must always be measured against the primordial question: What is good or evil? What must be done to have eternal life?
The moral theologian must therefore exercise careful discernment in the context of today’s prevalently scientific and technical culture, exposed as it is to the dangers of relativism, pragmatism and positivism. From the theological viewpoint, moral principles are not dependent upon the historical moment in which they are discovered. Moreover, the fact that some believers act without following the teachings of the Magisterium, or erroneously consider as morally correct a kind of behaviour declared by their Pastors as contrary to the law of God, cannot be a valid argument for rejecting the truth of the moral norms taught by the Church. The affirmation of moral principles is not within the competence of formal empirical methods. While not denying the validity of such methods, but at the same time not restricting its viewpoint to them, moral theology, faithful to the supernatural sense of the faith, takes into account first and foremost the spiritual dimension of the human heart and its vocation to divine love.
In fact, while the behavioural sciences, like all experimental sciences, develop an empirical and statistical concept of “normality”, faith teaches that this normality itself bears the traces of a fall from man’s original situation — in other words, it is affected by sin. Only Christian faith points out to man the way to return to “the beginning” (cf. Mt 19:8), a way which is often quite different from that of empirical normality. Hence the behavioural sciences, despite the great value of the information which they provide, cannot be considered decisive indications of moral norms. It is the Gospel which reveals the full truth about man and his moral journey, and thus enlightens and admonishes sinners; it proclaims to them God’s mercy, which is constantly at work to preserve them both from despair at their inability fully to know and keep God’s law and from the presumption that they can be saved without merit. God also reminds sinners of the joy of forgiveness, which alone grants the strength to see in the moral law a liberating truth, a grace-filled source of hope, a path of life.
Teaching moral doctrine involves the conscious acceptance of these intellectual, spiritual and pastoral responsibilities. Moral theologians, who have accepted the charge of teaching the Church’s doctrine, thus have a grave duty to train the faithful to make this moral discernment, to be committed to the true good and to have confident recourse to God’s grace.
While exchanges and conflicts of opinion may constitute normal expressions of public life in a representative democracy, moral teaching certainly cannot depend simply upon respect for a process: indeed, it is in no way established by following the rules and deliberative procedures typical of a democracy.Dissent, in the form of carefully orchestrated protests and polemics carried on in the media, is opposed to ecclesial communion and to a correct understanding of the hierarchical constitution of the People of God. Opposition to the teaching of the Church’s Pastors cannot be seen as a legitimate expression either of Christian freedom or of the diversity of the Spirit’s gifts. When this happens, the Church’s Pastors have the duty to act in conformity with their apostolic mission, insisting that the right of the faithful to receive Catholic doctrine in its purity and integrity must always be respected. “Never forgetting that he too is a member of the People of God, the theologian must be respectful of them, and be committed to offering them a teaching which in no way does harm to the doctrine of the faith”.
