I’m not sure images get much more powerful than the image Saturday from London: Pope Benedict, in Hyde Park, on his knees in adoration of our Lord and Savior in the Blessed Sacrament.

There are the controversial topics, the security threats, the celebrities, the history, the politics, but the heart of Pope Benedict’s trip to the United Kingdom is not his or anyone else’s agenda. It is Christ. It is praying for the desire to never stray from Him, who is truth. As England—and I only point fingers to help keep us straight!—surely does its share of straying.

From the Hyde Park vigil service (full text here):

At the end of his life, Newman would describe his life’s work as a struggle against the growing tendency to view religion as a purely private and subjective matter, as a question of personal opinion. Here is the first lesson we can learn from his life: in our day, when an intellectual and moral relativism threatens to sap the very foundations of our society, Newman reminds us that, as men and women made in the image and likeness of God, we were created to know the truth, to find in that truth our ultimate freedom and the fulfilment of our deepest human aspirations. In a word, we are meant to know Christ, who is himself “the way, and the truth, and the life” (John 14:6).

Newman’s life also teaches us that passion for the truth, intellectual honesty and genuine conversion are costly. The truth that sets us free cannot be kept to ourselves; it calls for testimony, it begs to be heard, and in the end its convincing power comes from itself and not from the human eloquence or arguments in which it may be couched. Not far from here, at Tyburn, great numbers of our brothers and sisters died for the faith; the witness of their fidelity to the end was ever more powerful than the inspired words that so many of them spoke before surrendering everything to the Lord. In our own time, the price to be paid for fidelity to the Gospel is no longer being hanged, drawn and quartered but it often involves being dismissed out of hand, ridiculed or parodied. And yet, the Church cannot withdraw from the task of proclaiming Christ and his Gospel as saving truth, the source of our ultimate happiness as individuals and as the foundation of a just and humane society.

Finally, Newman teaches us that if we have accepted the truth of Christ and committed our lives to him, there can be no separation between what we believe and the way we live our lives. Our every thought, word and action must be directed to the glory of God and the spread of his Kingdom. Newman understood this, and was the great champion of the prophetic office of the Christian laity. He saw clearly that we do not so much accept the truth in a purely intellectual act as embrace it in a spiritual dynamic that penetrates to the core of our being. Truth is passed on not merely by formal teaching, important as that is, but also by the witness of lives lived in integrity, fidelity and holiness; those who live in and by the truth instinctively recognize what is false and, precisely as false, inimical to the beauty and goodness which accompany the splendour of truth, veritatis splendor.
