The origins

7. The art which Christianity encountered in its early days was the ripe fruit of the classical world, articulating its aesthetic canons and embodying its values. Not only in their way of living and thinking, but also in the field of art, faith obliged Christians to a discernment which did not allow an uncritical acceptance of this heritage. Art of Christian inspiration began therefore in a minor key, strictly tied to the need for believers to contrive Scripture-based signs to express both the mysteries of faith and a “symbolic code” by which they could distinguish and identify themselves, especially in the difficult times of persecution. Who does not recall the symbols which marked the first appearance of an art both pictorial and plastic? The fish, the loaves, the shepherd: in evoking the mystery, they became almost imperceptibly the first traces of a new art.

When the Edict of Constantine allowed Christians to declare themselves in full freedom, art became a privileged means for the expression of faith. Majestic basilicas began to appear, and in them the architectural canons of the pagan world were reproduced and at the same time modified to meet the demands of the new form of worship. How can we fail to recall at least the old Saint Peter’s Basilica and the Basilica of Saint John Lateran, both funded by Constantine himself? Or Constantinople’s Hagia Sophia built by Justinian, with its splendours of Byzantine art?

While architecture designed the space for worship, gradually the need to contemplate the mystery and to present it explicitly to the simple people led to the early forms of painting and sculpture. There appeared as well the first elements of art in word and sound. Among the many themes treated by Augustine we find De Musica; and Hilary of Poitiers, Ambrose, Prudentius, Ephrem the Syrian, Gregory of Nazianzus and Paulinus of Nola, to mention but a few, promoted a Christian poetry which was often of high quality not just as theology but also as literature. Their poetic work valued forms inherited from the classical authors, but was nourished by the pure sap of the Gospel, as Paulinus of Nola put it succinctly: “Our only art is faith and our music Christ”.(12) A little later, Gregory the Great compiled the Antiphonarium and thus laid the ground for the organic development of that most original sacred music which takes its name from him. Gregorian chant, with its inspired modulations, was to become down the centuries the music of the Church’s faith in the liturgical celebration of the sacred mysteries. The “beautiful” was thus wedded to the “true”, so that through art too souls might be lifted up from the world of the senses to the eternal.

Along this path there were troubled moments. Precisely on the issue of depicting the Christian mystery, there arose in the early centuries a bitter controversy known to history as “the iconoclast crisis”. Sacred images, which were already widely used in Christian devotion, became the object of violent contention. The Council held at Nicaea in 787, which decreed the legitimacy of images and their veneration, was a historic event not just for the faith but for culture itself. The decisive argument to which the Bishops appealed in order to settle the controversy was the mystery of the Incarnation: if the Son of God had come into the world of visible realities—his humanity building a bridge between the visible and the invisible— then, by analogy, a representation of the mystery could be used, within the logic of signs, as a sensory evocation of the mystery. The icon is venerated not for its own sake, but points beyond to the subject which it represents.(13)

The Middle Ages

8. The succeeding centuries saw a great development of Christian art. In the East, the art of the icon continued to flourish, obeying theological and aesthetic norms charged with meaning and sustained by the conviction that, in a sense, the icon is a sacrament. By analogy with what occurs in the sacraments, the icon makes present the mystery of the Incarnation in one or other of its aspects. That is why the beauty of the icon can be best appreciated in a church where in the shadows burning lamps stir infinite flickerings of light. As Pavel Florensky has written: “By the flat light of day, gold is crude, heavy, useless, but by the tremulous light of a lamp or candle it springs to life and glitters in sparks beyond counting—now here, now there, evoking the sense of other lights, not of this earth, which fill the space of heaven”.(14)

In the West, artists start from the most varied viewpoints, depending also on the underlying convictions of the cultural world of their time. The artistic heritage built up over the centuries includes a vast array of sacred works of great inspiration, which still today leave the observer full of admiration. In the first place, there are the great buildings for worship, in which the functional is always wedded to the creative impulse inspired by a sense of the beautiful and an intuition of the mystery. From here came the various styles well known in the history of art. The strength and simplicity of the Romanesque, expressed in cathedrals and abbeys, slowly evolved into the soaring splendours of the Gothic. These forms portray not only the genius of an artist but the soul of a people. In the play of light and shadow, in forms at times massive, at times delicate, structural considerations certainly come into play, but so too do the tensions peculiar to the experience of God, the mystery both “awesome” and “alluring”. How is one to summarize with a few brief references to each of the many different art forms, the creative power of the centuries of the Christian Middle Ages? An entire culture, albeit with the inescapable limits of all that is human, had become imbued with the Gospel; and where theology produced the Summa of Saint Thomas, church art moulded matter in a way which led to adoration of the mystery, and a wonderful poet like Dante Alighieri could compose “the sacred poem, to which both heaven and earth have turned their hand”,(15) as he himself described the Divine Comedy.

Humanism and the Renaissance

9. The favourable cultural climate that produced the extraordinary artistic flowering of Humanism and the Renaissance also had a significant impact on the way in which the artists of the period approached the religious theme. Naturally, their inspiration, like their style, varied greatly, at least among the best of them. But I do not intend to repeat things which you, as artists, know well. Writing from this Apostolic Palace, which is a mine of masterpieces perhaps unique in the world, I would rather give voice to the supreme artists who in this place lavished the wealth of their genius, often charged with great spiritual depth. From here can be heard the voice of Michelangelo who in the Sistine Chapel has presented the drama and mystery of the world from the Creation to the Last Judgement, giving a face to God the Father, to Christ the Judge, and to man on his arduous journey from the dawn to the consummation of history. Here speaks the delicate and profound genius of Raphael, highlighting in the array of his paintings, and especially in the “Dispute” in the Room of the Signatura, the mystery of the revelation of the Triune God, who in the Eucharist befriends man and sheds light on the questions and expectations of human intelligence. From this place, from the majestic Basilica dedicated to the Prince of the Apostles, from the Colonnade which spreads out from it like two arms open to welcome the whole human family, we still hear Bramante, Bernini, Borromini, Maderno, to name only the more important artists, all rendering visible the perception of the mystery which makes of the Church a universally hospitable community, mother and travelling companion to all men and women in their search for God.

This extraordinary complex is a remarkably powerful expression of sacred art, rising to heights of imperishable aesthetic and religious excellence. What has characterized sacred art more and more, under the impulse of Humanism and the Renaissance, and then of successive cultural and scientific trends, is a growing interest in everything human, in the world, and in the reality of history. In itself, such a concern is not at all a danger for Christian faith, centred on the mystery of the Incarnation and therefore on God’s valuing of the human being. The great artists mentioned above are a demonstration of this. Suffice it to think of the way in which Michelangelo represents the beauty of the human body in his painting and sculpture.(16)

Even in the changed climate of more recent centuries, when a part of society seems to have become indifferent to faith, religious art has continued on its way. This can be more widely appreciated if we look beyond the figurative arts to the great development of sacred music through this same period, either composed for the liturgy or simply treating religious themes. Apart from the many artists who made sacred music their chief concern—how can we forget Pier Luigi da Palestrina, Orlando di Lasso, Tomás Luis de Victoria?—it is also true that many of the great composers—from Handel to Bach, from Mozart to Schubert, from Beethoven to Berlioz, from Liszt to Verdi—have given us works of the highest inspiration in this field.
