"Dear Brothers and sisters,
Continuing our journey through the Fathers of the Church, true stars that shine in the distance, at our meeting today we encounter a Pope who in 1754 Benedict XIV proclaimed a Doctor of the Church: St Leo the Great. As the nickname soon attributed to him by tradition suggests, he was truly one of the greatest Pontiffs to have honoured the Roman See and made a very important contribution to strengthening its authority and prestige. He was the first Bishop of Rome to have been called Leo, a name used subsequently by another 12 Supreme Pontiffs, and was also the first Pope whose preaching to the people who gathered round him during celebrations has come down to us. We spontaneously think of him also in the context of today's Wednesday General Audiences, events that in past decades have become a customary meeting of the Bishop of Rome with the faithful and the many visitors from every part of the world.

Leo was a Tuscan native. In about the year 430 AD, he became a deacon of the Church of Rome, in which he acquired over time a very important position. In the year 440 his prominent role induced Galla Placidia, who then ruled the Empire of the West, to send him to Gaul to heal a difficult situation. But in the summer of that year, Pope Sixtus III, whose name is associated with the magnificent mosaics in St Mary Major's, died, and it was Leo who was elected to succeed him. Leo heard the news precisely while he was carrying out his peace mission in Gaul. Having returned to Rome, the new Pope was consecrated on 29 September 440. This is how his Pontificate began. It lasted more than 21 years and was undoubtedly one of the most important in the Church's history. Pope Leo died on 10 November 461 and was buried near the tomb of St Peter. Today, his relics are preserved in one of the altars in the Vatican Basilica.

The times in which Pope Leo lived were very difficult: constant barbarian invasions, the gradual weakening of imperial authority in the West and the long, drawn-out social crisis forced the Bishop of Rome - as was to happen even more obviously a century and a half later during the Pontificate of Gregory the Great - to play an important role in civil and political events. This, naturally, could only add to the importance and prestige of the Roman See. The fame of one particular episode in Leo's life has endured. It dates back to 452 when the Pope, together with a Roman delegation, met Attila, chief of the Huns, in Mantua and dissuaded him from continuing the war of invasion by which he had already devastated the northeastern regions of Italy. Thus, he saved the rest of the Peninsula. This important event soon became memorable and lives on as an emblematic sign of the Pontiff's action for peace. Unfortunately, the outcome of another Papal initiative three years later was not as successful, yet it was a sign of courage that still amazes us: in the spring of 455 Leo did not manage to prevent Genseric's Vandals, who had reached the gates of Rome, from invading the undefended city that they plundered for two weeks. This gesture of the Pope - who, defenceless and surrounded by his clergy, went forth to meet the invader to implore him to desist - nevertheless prevented Rome from being burned and assured that the Basilicas of St Peter, St Paul and St John, in which part of the terrified population sought refuge, were spared.

We are familiar with Pope Leo's action thanks to his most beautiful sermons - almost 100 in a splendid and clear Latin have been preserved - and thanks to his approximately 150 letters. In these texts the Pontiff appears in all his greatness, devoted to the service of truth in charity through an assiduous exercise of the Word which shows him to us as both Theologian and Pastor. Leo the Great, constantly thoughtful of his faithful and of the people of Rome but also of communion between the different Churches and of their needs, was a tireless champion and upholder of the Roman Primacy, presenting himself as the Apostle Peter's authentic heir: the many Bishops who gathered at the Council of Chalcedon, the majority of whom came from the East, were well aware of this.

This Council, held in 451 and in which 350 Bishops took part, was the most important assembly ever to have been celebrated in the history of the Church. Chalcedon represents the sure goal of the Christology of the three previous Ecumenical Councils: Nicea in 325, Constantinople in 381 and Ephesus in 431. By the 6th century these four Councils that sum up the faith of the ancient Church were already being compared to the four Gospels. This is what Gregory the Great affirms in a famous letter (I, 24): "I confess that I receive and revere, as the four books of the Gospel so also the four Councils", because on them, Gregory explains further, "as on a four-square stone, rises the structure of the holy faith". The Council of Chalcedon, which rejected the heresy of Eutyches who denied the true human nature of the Son of God, affirmed the union in his one Person, without confusion and without separation, of his two natures, human and divine.

The Pope asserted this faith in Jesus Christ, true God and true man, in an important doctrinal text addressed to the Bishop of Constantinople, the so-called Tome to Flavian which, read at Chalcedon, was received by the Bishops present with an eloquent acclamation. Information on it has been preserved in the proceedings of the Council: "Peter has spoken through the mouth of Leo", the Council Fathers announced in unison. From this intervention in particular, but also from others made during the Christological controversy in those years, it is clear that the Pope felt with special urgency his responsibilities as Successor of Peter, whose role in the Church is unique since "to one Apostle alone was entrusted what was communicated to all the Apostles", as Leo said in one of his sermons for the Feast of Sts Peter and Paul (83, 2). And the Pontiff was able to exercise these responsibilities, in the West as in the East, intervening in various circumstances with caution, firmness and lucidity through his writings and legates. In this manner he showed how exercising the Roman Primacy was as necessary then as it is today to effectively serve communion, a characteristic of Christ's one Church.

Aware of the historical period in which he lived and of the change that was taking place - from pagan Rome to Christian Rome - in a period of profound crisis, Leo the Great knew how to make himself close to the people and the faithful with his pastoral action and his preaching. He enlivened charity in a Rome tried by famines, an influx of refugees, injustice and poverty. He opposed pagan superstitions and the actions of Manichaean groups. He associated the liturgy with the daily life of Christians: for example, by combining the practice of fasting with charity and almsgiving above all on the occasion of the Quattro tempora, which in the course of the year marked the change of seasons. In particular, Leo the Great taught his faithful - and his words still apply for us today - that the Christian liturgy is not the memory of past events, but the actualization of invisible realities which act in the lives of each one of us. This is what he stressed in a sermon on Easter, to be celebrated in every season of the year "not so much as something of the past as rather an event of the present". All this fits into a precise project, the Holy Pontiff insisted: just as, in fact, the Creator enlivened with the breath of rational life man formed from the dust of the ground, after the original sin he sent his Son into the world to restore to man his lost dignity and to destroy the dominion of the devil through the new life of grace.

This is the Christological mystery to which St Leo the Great, with his Letter to the Council of Ephesus, made an effective and essential contribution, confirming for all time - through this Council - what St Peter said at Caesarea Philippi. With Peter and as Peter, he professed: "You are the Christ, the Son of the living God". And so it is that God and man together "are not foreign to the human race but alien to sin." Through the force of this Christological faith he was a great messenger of peace and love. He thus shows us the way: in faith we learn charity. Let us therefore learn with St Leo the Great to believe in Christ, true God and true Man, and to implement this faith every day in action for peace and love of neighbour."

St Leo the Great - Reading from his sermons:

Although the Church is ordered in various ranks so that the whole is made up of different members, yet (as Paul says) we are all one in Christ. Office does not constitute between members a division such that the insignificance of any part affects its union with the head. And so we say that in the unity of our faith and baptism we enjoy an undivided fellowship and a dignity common to us all; which the most blessed apostle Peter expressed in his inspired words: 'Like living stones be yourselves built up into a spiritual house, to be a holy priesthood, to offer spiritual spiritual sacrifices acceptable to God through Jesus Christ.' And father on he says: 'You are a chosen race, a royal priesthood, a holy nation, God's own people.'

In baptism the sign of the cross makes kings of all who are reborn in Christ, and the anointing of the Holy Spirit consecrates them priests. So, apart from the particular obligations of our ministry, any Christian who has the gifts of rational and of spiritual understanding knows he is a member of a kingly race and shares in the priestly office. For what could be more royal than a soul which by subjecting itself to God becomes ruler of its own body? Or what more priestly when it consecrates a pure conscience to God and offers on the altar of its heart the spotless sacrifice of its devotion? By the grace of God his is common to all. But it is also a gracious and a religious thing in you that on the day of my consecration you rejoice as for an honour that is your own. Thus the one sacrament which confers the high priesthood is celebrated in the whole body of the Church. When the oil of consecration is poured, the grace flows more abundantly over the higher orders indeed, but it flows unsparingly too over the lower.

Therefore, my dear brethren, if we have cause for rejoicing together at the fact that we share this spiritual gift, we shall have a much better and more exact cause to be joyful if we do not dwell on our own lowliness but rather turn our mind to contemplate the glory of the blessed apostle Peter. This will be much more appropriate, and more profitable to us, for then we shall be celebrating this feast in honour of the one who was so flooded with grace from the very fount of all grace that whereas he had so many gifts which he alone received, no one had any that did not pass through his hands. When the Word made flesh was living among us, Christ had already devoted himself entirely to the redemption of mankind.

In fact the latter appears twice in the same scene, portrayed in the guise of Pope Leo the Great and as cardinal. According to legend, the miraculous apparition of Saints Peter and Paul armed with swords during the meeting between Pope Leo the Great and Attila (452 AD) caused the king of the Huns to desist from invading Italy and marching on Rome.
