4. Charged with the promotion and the defense of faith and morals in the universal Church,[²] the Sacred Congregation for the Doctrine of the Faith proposes to recall this teaching in its essential aspects to all the faithful. Thus in showing the unity of the Church, it will confirm by the authority proper to the Holy See what the bishops have opportunely undertaken. It hopes that all the faithful, including those who might have been unsettled by the controversies and new opinions, will understand that it is not a question of opposing one opinion to another, but of transmitting to the faithful a constant teaching of the supreme Magisterium, which teaches moral norms in the light of faith.[³] It is therefore clear that this declaration necessarily entails a grave obligation for Christian consciences.[⁴] May God deign to enlighten also all men who strive with their whole heart to "act in truth" (Jn. 3:21).
