Cardinal Newman’s motto, Cor ad cor loquitur, or “Heart speaks unto heart”, gives us an insight into his understanding of the Christian life as a call to holiness, experienced as the profound desire of the human heart to enter into intimate communion with the Heart of God. He reminds us that faithfulness to prayer gradually transforms us into the divine likeness. As he wrote in one of his many fine sermons, “a habit of prayer, the practice of turning to God and the unseen world in every season, in every place, in every emergency – prayer, I say, has what may be called a natural effect in spiritualizing and elevating the soul. A man is no longer what he was before; gradually … he has imbibed a new set of ideas, and become imbued with fresh principles” (Parochial and Plain Sermons, iv, 230-231). Today’s Gospel tells us that no one can be the servant of two masters (cf.Lk 16:13), and Blessed John Henry’s teaching on prayer explains how the faithful Christian is definitively taken into the service of the one true Master, who alone has a claim to our unconditional devotion (cf. Mt 23:10). Newman helps us to understand what this means for our daily lives: he tells us that our divine Master has assigned a specific task to each one of us, a “definite service”, committed uniquely to every single person: “I have my mission”, he wrote, “I am a link in a chain, a bond of connexion between persons. He has not created me for naught. I shall do good, I shall do his work; I shall be an angel of peace, a preacher of truth in my own place … if I do but keep his commandments and serve him in my calling” (Meditations and Devotions, 301-2) ■ Benedict XVI, Mass with beatification of Cardinal John Henry Newman.
