Always summoning him to love good and avoid evil, the voice of conscience can when necessary speak to his heart more specifically: 'do this, shun that'. This is the meaning of Jesus' saying: "He who does what is true comes to the light" (Jn 3:21). He was not really Paul. And he answers: "But who can doubt that love comes first? Decree on Priestly Formation Optatam Totius, 16.15. Who controls the present controls the past. In the Old Covenant the object of the promise was the possession of a land where the people would be able to live in freedom and in accordance with righteousness (cf. Love of neighbour would mean above all and even exclusively respect for his freedom to make his own decisions. Contemplation of Jesus Crucified is thus the highroad which the Church must tread every day if she wishes to understand the full meaning of freedom: the gift of self in service to God and one's brethren. Hence the Psalmist prays: "Let the light of your face shine on us, O Lord" (Ps 4:6). According to some, it appears that one no longer need acknowledge the enduring absoluteness of any moral value. Indeed, each of the Beatitudes promises, from a particular viewpoint, that very "good" which opens man up to eternal life, and indeed is eternal life. For the time will come when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own likings, and will turn away from listening to the truth and wander into myths. Dear Brothers in the Episcopate, we must not be content merely to warn the faithful about the errors and dangers of certain ethical theories. 48. In a positive way, the Church seeks, with great love, to help all the faithful to form a moral conscience which will make judgments and lead to decisions in accordance with the truth, following the exhortation of the Apostle Paul: "Do not be conformed to this world but be transformed by the renewal of your mind, that you may prove what is the will of God, what is good and acceptable and perfect" (Rom 12:2). ibid., I-II, q. Responsibility demands as much. cit., 1562-1568. And, in turn, only the person himself knows what his own response is to the voice of conscience. To the affirmation that one has a duty to follow one's conscience is unduly added the affirmation that one's moral judgment is true merely by the fact that it has its origin in the conscience. And he concluded: "It follows that the natural law is itself the eternal law, implanted in beings endowed with reason, and inclining them towards their right action and end; it is none other than the eternal reason of the Creator and Ruler of the universe".83. In Christ's name and with his authority they have exhorted, passed judgment and explained. With the guarantee of assistance from the Spirit of truth they have contributed to a better understanding of moral demands in the areas of human sexuality, the family, and social, economic and political life. He cares for man not "from without", through the laws of physical nature, but "from within", through reason, which, by its natural knowledge of God's eternal law, is consequently able to show man the right direction to take in his free actions.81 In this way God calls man to participate in his own providence, since he desires to guide the world â not only the world of nature but also the world of human persons â through man himself, through man's reasonable and responsible care. When people ask the Church the questions raised by their consciences, when the faithful in the Church turn to their Bishops and Pastors, the Church's reply contains the voice of Jesus Christ, the voice of the truth about good and evil. Even so, "care will have to be taken not to reduce mortal sin to an act of 'fundamental option' â as is commonly said today â against God", seen either as an explicit and formal rejection of God and neighbour or as an implicit and unconscious rejection of love. Pilate's question: "What is truth" reflects the distressing perplexity of a man who often no longer knows who he is, whence he comes and where he is going. Certainly there is a long and difficult road ahead; bringing about such a renewal will require enormous effort, especially on account of the number and the gravity of the causes giving rise to and aggravating the situations of injustice present in the world today. Cf. Indeed, something more serious has happened: man is no longer convinced that only in the truth can he find salvation. Rather, faith is a lived knowledge of Christ, a living remembrance of his commandments, and a truth to be lived out.
