The title above is taken from the Gospel this weekend ( Matt. 5:37) where Jesus directs his disciples towards honesty, truthfulness and transparency. In an age of 'Fake News', the following is an extract from the Catechism of the Catholic Church that elaborates on this fundamental calling of Christians, to be people of honesty and truth.
'I. Living in the Truth
'The Old Testament attests that God is the source of all truth. His Word is truth. His Law is truth. His "faithfulness endures to all generations." Since God is "true," the members of his people are called to live in the truth. In Jesus Christ, the whole of God's truth has been made manifest. "Full of grace and truth," he came as the "light of the world," he is the Truth. "Whoever believes in me may not remain in darkness." The disciple of Jesus continues in his word so as to know "the truth [that] will make you free" and that sanctifies. To follow Jesus is to live in "the Spirit of truth," whom the Father sends in his name and who leads "into all the truth." To his disciples Jesus teaches the unconditional love of truth: "Let what you say be simply 'Yes or No.'
Man tends by nature toward the truth. He is obliged to honor and bear witness to it: "It is in accordance with their dignity that all men, because they are persons . . . are both impelled by their nature and bound by a moral obligation to seek the truth, especially religious truth. They are also bound to adhere to the truth once they come to know it and direct their whole lives in accordance with the demands of truth."
Truth as uprightness in human action and speech is called truthfulness, sincerity, or candor. Truth or truthfulness is the virtue which consists in showing oneself true in deeds and truthful in words, and in guarding against duplicity, dissimulation, and hypocrisy. "Men could not live with one another if there were not mutual confidence that they were being truthful to one another." The virtue of truth gives another his just due. Truthfulness keeps to the just mean between what ought to be expressed and what ought to be kept secret: it entails honesty and discretion. In justice, "as a matter of honor, one man owes it to another to manifest the truth." The disciple of Christ consents to "live in the truth," that is, in the simplicity of a life in conformity with the Lord's example, abiding in his truth. "If we say we have fellowship with him while we walk in darkness, we lie and do not live according to the truth' (2465-2470).
II. To Bear Witness to the Truth
'Before Pilate, Christ proclaims that he "has come into the world, to bear witness to the truth." The Christian is not to "be ashamed then of testifying to our Lord." In situations that require witness to the faith, the Christian must profess it without equivocation, after the example of St. Paul before his judges. We must keep "a clear conscience toward God and toward men."
The duty of Christians to take part in the life of the Church impels them to act as witnesses of the Gospel and of the obligations that flow from it. This witness is a transmission of the faith in words and deeds. Witness is an act of justice that establishes the truth or makes it known. All Christians by the example of their lives and the witness of their word, wherever they live, have an obligation to manifest the new man which they have put on in Baptism and to reveal the power of the Holy Spirit by whom they were strengthened at Confirmation.
Martyrdom is the supreme witness given to the truth of the faith: it means bearing witness even unto death. the martyr bears witness to Christ who died and rose, to whom he is united by charity. He bears witness to the truth of the faith and of Christian doctrine. He endures death through an act of fortitude. "Let me become the food of the beasts, through whom it will be given me to reach God."
The Church has painstakingly collected the records of those who persevered to the end in witnessing to their faith. These are the acts of the Martyrs. They form the archives of truth written in letters of blood:
Neither the pleasures of the world nor the kingdoms of this age will be of any use to me.
It is better for me to die [in order to unite myself] to Christ Jesus than to reign over the ends of the earth. I seek him who died for us; I desire him who rose for us. My birth is approaching. .. I bless you for having judged me worthy from this day and this hour to be counted among your martyrs.... You have kept your promise, God of faithfulness and truth. For this reason and for everything, I praise you, I bless you, I glorify you through the eternal and heavenly High Priest, Jesus Christ, your beloved Son. Through him, who is with you and the Holy Spirit, may glory be given to you, now and in the ages to come. Amen' (From the Martyrdom of St Polycarp).
III The Use of Social Media and Truth
Within modern society the communications media play a major role in information, cultural promotion, and formation. This role is increasing, as a result of technological progress, the extent and diversity of the news transmitted, and the influence exercised on public opinion.
The information provided by the media is at the service of the common good. Society has a right to information based on truth, freedom, justice, and solidarity:
The proper exercise of this right demands that the content of the communication be true and - within the limits set by justice and charity - complete. Further, it should be communicated honestly and properly. This means that in the gathering and in the publication of news, the moral law and the legitimate rights and dignity of man should be upheld.
"It is necessary that all members of society meet the demands of justice and charity in this domain. They should help, through the means of social communication, in the formation and diffusion of sound public opinion."286 Solidarity is a consequence of genuine and right communication and the free circulation of ideas that further knowledge and respect for others.
The means of social communication (especially the mass media) can give rise to a certain passivity among users, making them less than vigilant consumers of what is said or shown. Users should practice moderation and discipline in their approach to the mass media. They will want to form enlightened and correct consciences the more easily to resist unwholesome influences.
By the very nature of their profession, journalists have an obligation to serve the truth and not offend against charity in disseminating information. They should strive to respect, with equal care, the nature of the facts and the limits of critical judgment concerning individuals. They should not stoop to defamation.
"Civil authorities have particular responsibilities in this field because of the common good.... It is for the civil authority ... to defend and safeguard a true and just freedom of information." By promulgating laws and overseeing their application, public authorities should ensure that "public morality and social progress are not gravely endangered" through misuse of the media. Civil authorities should punish any violation of the rights of individuals to their reputation and privacy. They should give timely and reliable reports concerning the general good or respond to the well-founded concerns of the people. Nothing can justify recourse to disinformation for manipulating public opinion through the media. Interventions by public authority should avoid injuring the freedom of individuals or groups.
Moral judgment must condemn the plague of totalitarian states which systematically falsify the truth, exercise political control of opinion through the media, manipulate defendants and witnesses at public trials, and imagine that they secure their tyranny by strangling and repressing everything they consider "thought crimes."
