Frequency of receiving the Eucharist - earliest reference?

"And on the day which is called the day of the sun there is an assembly of all who live in the towns or in the country; and the memoirs of the Apostles or the writings of the Prophets are read, as long as time permits. Then the reader ceases, and the president [i.e., the bishop or his designate] speaks, admonishing us and exhorting us to imitate these excellent examples. Then we arise all together and offer prayers; and, as we said before, when we have concluded our prayer, bread is brought, and wine and water, and the president in like manner offers up prayers and thanksgivings with all his might; and the people assent with "Amen"; and there is the distribution and partaking by all of the Eucharistic elements; and to them that are not present they are sent by the hand of the deacons."

St. Justin Martyr, First Apology 

Cardinal Ratzinger on Liturgy - 2

“For fostering a true consciousness in liturgical matters, it is also important that the proscription against the form of liturgy in valid use up to 1970 should be lifted. Anyone who nowadays advocates the continuing existence of this liturgy or takes part in it is treated like a leper; all tolerance ends here. There has never been anything like this in history; in doing this we are despising and proscribing the Church’s whole past. How can one trust her present if things are that way? I must say, quite openly, that I don’t understand why so any of my episcopal brethren have to a great extent submitted to this rule of intolerance, which for no apparent reason is opposed to making the necessary inner reconciliations within the Church.”

Benedict XVI on St. Gregory the Great

Pope Saint Gregory the Great

His exceptional, I would say, almost unique figure is an example to hold up both to pastors of the Church and to public administrators: indeed, he was first Prefect and then Bishop of Rome. As an imperial official, he was so distinguished for his administrative talents and moral integrity that he served in the highest civil office, Praefectus Urbis, when he was only 30 years old. 

Within him, however, the vocation to the monastic life was maturing; he embraced it in 574, upon his father's death. The Benedictine Rule then became the backbone of his existence. Even when the Pope sent him as his Representative to the Emperor of the East in Constantinople, he maintained a simple and poor monastic lifestyle.

Called back to Rome, Gregory, although living in a monastery, was a close collaborator of Pope Pelagius II, and when the Pope died, the victim of a plague epidemic, Gregory was acclaimed by all as his Successor.

He sought in every way to escape this appointment but in the end was obliged to yield. He left the cloister reluctantly and dedicated himself to the community, aware of doing his duty and being a simple and poor "servant of the servants of God".

"He is not really humble," he wrote, "who understands that he must be a leader of others by decree of the divine will and yet disdains this pre-eminence. If, on the contrary, he submits to divine dispositions, and does not have the vice of obstinacy, and is prepared to benefit others with those gifts when the highest dignity of governing souls is imposed on him, he must flee from it with his heart, but against his will, he must obey" ( Pastoral Rule, I, 6). It is like a dialogue that the Pope has with himself at that time.

With prophetic foresight, Gregory intuited that a new civilization was being born from the encounter of the Roman legacy with so-called "barbarian" peoples, thanks to the cohesive power and moral elevation of Christianity. Monasticism was proving to be a treasure not only for the Church but for the whole of society.

With delicate health but strong moral character St Gregory the Great carried out intense pastoral and civil action. He left a vast collection of letters, wonderful homilies, a famous commentary on the Book of Job and writings on the life of St Benedict, as well as numerous liturgical texts, famous for the reform of song that was called "Gregorian", after him.

However, his most famous work is certainly the Pastoral Rule, which had the same importance for the clergy as the Rule of St Benedict had for monks in the Middle Ages.

The life of a pastor of souls must be a balanced synthesis of contemplation and action, inspired by the love "that rises wonderfully to high things when it is compassionately drawn to the low things of neighbours; and the more kindly it descends to the weak things of this world, the more vigorously it recurs to the things on high" (II, 5).

In this ever timely teaching, the Fathers of the Second Vatican Council found inspiration to outline the image of today's Pastor.

Let us pray to the Virgin Mary that the example and teaching of St Gregory the Great may be followed by pastors of the Church and also by those in charge of civil institutions.

Benedict XVI on the Chair of St. Peter

Dear Brothers and Sisters! The Latin liturgy celebrates today the feast of the Chair of Peter. It is a very ancient tradition, witnessed in Rome since the end of the fourth century, which renders thanksgiving to God for the mission entrusted to the Apostle Peter and his successors.

"Cathedra" literally means the established seat of the bishop, located in the mother church of a diocese, which for this reason is called "cathedral," and it is the symbol of the authority of the bishop and, in particular, of his "magisterium," that is, of the evangelical teaching that he, insofar as a successor of the apostles, is called to guard and transmit to the Christian community.

When the bishop takes possession of the local Church that is entrusted to him, he, bearing the miter and the shepherd's crosier, sits on the cathedra. From that seat he will guide, as teacher and shepherd, the journey of the faithful in faith, hope and charity.

Which was, then, the "cathedra" if St. Peter? He, chosen by Christ as "rock" on which to build the Church (cf. Matthew 16:18), began his ministry in Jerusalem, after the ascension of the Lord and Pentecost. The first "seat" of the Church was the Cenacle, and in all probability in that room, where Mary, the Mother of Jesus, also prayed with the disciples, a special place was reserved for Simon Peter.

Subsequently, the see of Peter was Antioch, a city situated on the Oronte River in Syria, today Turkey, which at the time was the third metropolis of the Roman Empire after Rome and Alexandria in Egypt. Of that city, evangelized by Barnabas and Paul, where "for the first time the disciples were called Christians" (Acts 11:26), Peter was the first Bishop.

In fact, the Roman Martyrology, before the reform of the calendar, established also a specific celebration of the Chair of Peter at Antioch. From there, Providence led Peter to Rome, where he concluded with martyrdom his course of service to the Gospel. For this reason, the See of Rome, which had received the greatest honor, received also the task entrusted by Christ to Peter of being at the service of all the local Churches for the building and unity of the whole People of God.

In this way the See of Rome came to be known as that of the Successor of Peter, and the "cathedra" of its Bishop represented that of the apostle charged by Christ to feed all his flock. It is attested by the most ancient Fathers of the Church, as for example St. Irenaeus, bishop of Lyon, who in his treatise "Against Heresies" describes the Church of Rome as "greatest and most ancient, known by all; … founded and constituted at Rome by the two glorious Apostles Peter and Paul"; and he adds: "With this Church, because of her outstanding superiority, the universal Church must be in agreement, that is, the faithful everywhere" (III, 3, 2-3).

Tertullian, for his part, affirms: "How blessed this Church of Rome is! The Apostles themselves shed on her, with their blood, the whole of the doctrine" ("La Prescrizione degli Eretici," 36). The Chair of the Bishop of Rome represents, therefore, not only his service to the Roman community, but also his mission of guide of the whole People of God.

To celebrate the "Chair" of Peter, as we do today, means, therefore, to attribute to it a strong spiritual significance and to recognize in it a privileged sign of the love of God, good and eternal Shepherd, who wants to gather the whole of his Church and guide her along the way of salvation.

Among so many testimonies of the Fathers, I would like to refer to that of St. Jerome, taken from a letter of his to the Bishop of Rome, particularly interesting because he makes explicit reference in fact to the "chair" of Peter, presenting it as the safe harbor of truth and peace. Jerome writes thus: "I decided to consult the chair of Peter, where that faith is found exalted by the lips of an Apostle; I now come to ask for nourishment for my soul there, where once you received the garment of Christ. I follow no leader save Christ, so I enter into communion with your beatitude, that is, with the chair of Peter for this I know is the rock upon which the Church is built! ("Le Lettere," I, 15,1-2).

Dear Brothers and Sisters, in the apse of St. Peter's Basilica, as you know, is found the monument to the Chair of the Apostle, a mature work of Bernini, made in the shape of a great bronze throne, supported by the statues of four Doctors of the Church, two from the West, St. Augustine and St. Ambrose, and two from the East, St. John Chrysostom and St. Athanasius.

I invite you to pause before that evocative work, which today it is possible to admire decorated with so many candles, and pray in a particular way for the ministry that God has entrusted to me. Raising one's gaze to the alabaster glass window that opens precisely above the chair, invoke the Holy Spirit, so that he will always sustain with his light and strength my daily service to the whole Church. 

Benedict XVI, General Audience, Rome, 22 February 2006.
