Christ ascended the cross as a unique King: as the eternal witness to the truth. “For this I was born, and for this I came into the world: to bear witness to the truth” (Jn 18:37). This witness is the measure of our deeds. The measure of life. The truth for which Christ gave his life – which he confirmed through the Resurrection – is the fundamental source of human dignity. Christ’s kingdom is manifested, as the Council teaches, in the “kingship” of man. We must know, in this light, how to participate in every sphere of contemporary life and to shape it. Indeed, in our times, there is no shortage of proposals addressed to man, nor of programmes invoked for his good. May we know how to re-examine them in the light of the full truth about man, the truth confirmed by the words and the cross of Christ!
May we know how to discern them well! Is what they declare expressed in accordance with the measure of man’s true dignity? Does the freedom they proclaim serve the kingly dignity of the being created in God’s image, or, on the contrary, does it pave the way for its deprivation or constraint? For example: do marital infidelity—even if sanctioned by divorce—or the lack of responsibility for conceived life—even if modern technology teaches how to dispose of it—serve man’s true freedom or express his dignity? Certainly, all moral permissiveness is not based on human dignity and does not educate man in it.
[Pope John Paul II, 25 November 1979]
