The Holy Door of the Jubilee of the Year 2000 should be symbolically wider than those of previous Jubilees, because humanity, upon reaching this goal, will leave behind not just a century but a millennium. It is fitting that the Church should make this passage with a clear awareness of what has happened to her during the last ten centuries. She cannot cross the threshold of the new millennium without encouraging her children to purify themselves, through repentance, of past errors and instances of infidelity, inconsistency, and slowness to act. Acknowledging the weaknesses of the past is an act of honesty and courage which helps us to strengthen our faith, which alerts us to face today's temptations and challenges and prepares us to meet them.

34. Among the sins which require a greater commitment to repentance and conversion should certainly be counted those which have been detrimental to the unity willed by God for his People. In the course of the thousand years now drawing to a close, even more than in the first millennium, ecclesial communion has been painfully wounded, a fact "for which, at times, men of both sides were to blame".(17) Such wounds openly contradict the will of Christ and are a cause of scandal to the world.(18) These sins of the past unfortunately still burden us and remain ever present temptations. It is necessary to make amends for them, and earnestly to beseech Christ's forgiveness.

In these last years of the millennium, the Church should invoke the Holy Spirit with ever greater insistence, imploring from him the grace of Christian unity. This is a crucial matter for our testimony to the Gospel before the world. Especially since the Second Vatican Council many ecumenical initiatives have been undertaken with generosity and commitment: it can be said that the whole activity of the local Churches and of the Apostolic See has taken on an ecumenical dimension in recent years. The Pontifical Council for the Promotion of Christian Unity has become an important catalyst in the movement towards full unity.

We are all however aware that the attainment of this goal cannot be the fruit of human efforts alone, vital though they are. Unity, after all, is a gift of the Holy Spirit. We are asked to respond to this gift responsibly, without compromise in our witness to the truth, generously implementing the guidelines laid down by the Council and in subsequent documents of the Holy See, which are also highly regarded by many Christians not in full communion with the Catholic Church.

This then is one of the tasks of Christians as we make our way to the Year 2000. The approaching end of the second millennium demands of everyone an examination of conscience and the promotion of fitting ecumenical initiatives, so that we can celebrate the Great Jubilee, if not completely united, at least much closer to overcoming the divisions of the second millennium. As everyone recognizes, an enormous effort is needed in this regard. It is essential not only to continue along the path of dialogue on doctrinal matters, but above all to be more committed to prayer for Christian unity. Such prayer has become much more intense after the Council, but it must increase still more, involving an ever greater number of Christians, in unison with the great petition of Christ before his Passion: "Father ... that they also may all be one in us" (Jn 17:21).

35. Another painful chapter of history to which the sons and daughters of the Church must return with a spirit of repentance is that of the acquiescence given, especially in certain centuries, to intolerance and even the use of violence in the service of truth.

It is true that an accurate historical judgment cannot prescind from careful study of the cultural conditioning of the times, as a result of which many people may have held in good faith that an authentic witness to the truth could include suppressing the opinions of others or at least paying no attention to them. Many factors frequently converged to create assumptions which justified intolerance and fostered an emotional climate from which only great spirits, truly free and filled with God, were in some way able to break free. Yet the consideration of mitigating factors does not exonerate the Church from the obligation to express profound regret for the weaknesses of so many of her sons and daughters who sullied her face, preventing her from fully mirroring the image of her crucified Lord, the supreme witness of patient love and of humble meekness. From these painful moments of the past a lesson can be drawn for the future, leading all Christians to adhere fully to the sublime principle stated by the Council: "The truth cannot impose itself except by virtue of its own truth, as it wins over the mind with both gentleness and power".(19)

36. Many Cardinals and Bishops expressed the desire for a serious examination of conscience above all on the part of the Church of today. On the threshold of the new Millennium Christians need to place themselves humbly before the Lord and examine themselves on the responsibility which they too have for the evils of our day. The present age in fact, together with much light, also presents not a few shadows.

How can we remain silent, for example, about the religious indifference which causes many people today to live as if God did not exist, or to be content with a vague religiosity, incapable of coming to grips with the question of truth and the requirement of consistency? To this must also be added the widespread loss of the transcendent sense of human life, and confusion in the ethical sphere, even about the fundamental values of respect for life and the family. The sons and daughters of the Church too need to examine themselves in this regard. To what extent have they been shaped by the climate of secularism and ethical relativism? And what responsibility do they bear, in view of the increasing lack of religion, for not having shown the true face of God, by having "failed in their religious, moral, or social life"? (20)

It cannot be denied that, for many Christians, the spiritual life is passing through a time of uncertainty which affects not only their moral life but also their life of prayer and the theological correctness of their faith. Faith, already put to the test by the challenges of our times, is sometimes disoriented by erroneous theological views, the spread of which is abetted by the crisis of obedience vis-à-vis the Church's Magisterium.
