Against the Doctrine of Double Truth

The greatest danger I perceive to the new evangelization of the West, including of Germany, is the return of the doctrine of double truth, a belief that is of Gnostic origin and which Irenaeus of Lyon already refuted with Catholic hermeneutics. The unified wholeness of revelation is held and conveyed by the Church through sacred Scripture, apostolic tradition, and the magisterium of the bishops. Accordingly, the Second Vatican Council, in its Dogmatic Constitution on Divine Revelation (Dei Verbum), affirmed the supernatural nature of faith and the sacramentality of the Church. It asserted these against the immanentization of faith and the secularization of the Church, as well as against Enlightenment rationalism, which reduced Christianity to a natural morality (Kant), and Romantic irrationalism, which distorted rational faith into mystical sentimentalism (Rousseau).
