But today the prob- lem goes far beyond the necessary recognition of these personal situations. Pope Francis and Pope Emeritus Benedict embraced each other warmly at a ceremony held in the Vatican gardens early on Friday before the release of the encyclical to consecrate a new monument to St Michael the Archangel, patron of Vatican City. Man alone, among all visible creatures, is "capable of knowing and loving his Creator". The twentieth century will have been an era of massive attacks on life, an endless series of wars and a continual taking of innocent human life. As Cardinal Karol Wojtyla he was influential in the writing of several documents from Vatican II, not the least of which was Gaudium et Spes — the Pastoral Constitution on the Church in the Modern World — from which he never tires of quoting in his many encyclicals and apostolic letters. While many claim pornography harms no one and thus is okay nothing could be farther from the truth. The Exodus was a foundational experience and a model for the future. At the same time it highlights why this gift is falsified by extramarital or contraceptive sex that sever sexual union from its inherent meanings of unconditional fidelity and life-giving fruitfulness. The full meaning of the body and hence the human person is revealed only when the man stands over against another unique way of being human—woman. The source of this "great joy" is the Birth of the Saviour; but Christmas also reveals the full meaning of every human birth, and the joy which accompanies the Birth of the Messiah is thus seen to be the foundation and fulfilment of joy at every child born into the world cf. My own feeling is that the church needs to grow in its understanding of human sexuality to take into account what the human sciences have learned in recent years. May these words reach all the sons and daughters of the Church! The contemporary scene, moreover, is becoming even more alarming by reason of the proposals, advanced here and there, to justify even infanticide, following the same arguments used to justify the right to abortion. This is also how he spoke of himself to Martha, the sister of Lazarus: In such a context suffering, an inescapable burden of human existence but also a factor of possible personal growth, is "censored", rejected as useless, indeed opposed as an evil, always and in every way to be avoided. This is the death of true freedom: In this way, any reference to common values and to a truth absolutely binding on everyone is lost, and social life ventures on to the shifting sands of complete relativism.
