It must be said once and for all: it is self-contradictory to be open-minded to error. It is like praising a susceptibility for disease as a particular sign of health. No, only the truth makes us free and lets us participate in real universality. It is a special sign of this freedom and universality, and of open-mindedness, to be immune to error, especially to philosophical and metaphysical error, and pre-eminently to heresy, to any teaching incompatible with the divine Revelation of Christ.
