St. Anicetus and Date of Easter

Fr. Scott Haynes

St. Anicetus is remembered not because he left behind dramatic writings or because his pontificate was filled with outward spectacle, but because in a moment of strain he helped the Church show her true face. He stands before us as a shepherd of peace, a guardian of sacred order, and a witness to the truth that fidelity and charity must remain together. His memory is especially linked to the question of Easter, and at first this may sound to a modern reader like a narrow or technical issue. Yet it was nothing of the kind. It touched the deepest mystery of Christian life: how the Church should mark the Passion and Resurrection of the Lord in time. (New Advent)

To understand why this mattered so much, we must first understand the month of Nisan. Nisan is the spring month of the Jewish religious year, the month in which Passover is kept. In terms familiar to us, it usually falls somewhere in March and April, though not on the same civil dates every year. That is because the Jewish calendar is not like the civil calendar most of us use today. The Jewish calendar is lunisolar. Its months follow the cycle of the moon, but the year is adjusted so that the feasts remain in their proper seasons. Nisan therefore returns in the spring, but its exact correspondence to our calendar shifts from year to year. (Encyclopedia Britannica)

This is why the phrase “the 14th day of Nisan” needs explanation. It does not mean April 14 in the modern calendar. It means the fourteenth day of the Jewish month of Nisan, counted according to the sacred reckoning of Israel. In ancient Jewish life, Passover was fixed to this season. The scriptural memory of the lamb, the blood, the deliverance from Egypt, and the beginning of freedom all belonged to this holy time. So when certain early Christians wished to keep the Christian Pasch on the 14th of Nisan, they were not choosing a random number. They were seeking to remain close to the biblical hour of the Lord’s Passion, when Christ, the true Paschal Lamb, offered Himself for the life of the world. (Encyclopedia Britannica)

Here the modern reader can begin to feel the depth of the old controversy. The Christians of Asia Minor, later called Quartodecimans, kept the Christian Pasch on the 14th day of Nisan, whatever day of the week it happened to be. Their concern was to preserve the date itself, because it was bound to the sacred scriptural pattern of Passover and to the Passion of Christ. Christians in Rome and in many other churches, however, insisted that the annual feast should always be celebrated on Sunday, because Sunday was the day of the Lord’s Resurrection and had already become the weekly day of Christian worship. So the disagreement was not between people who cared deeply and people who did not. It was between Christians trying, in two different ways, to honor the same saving mystery. (New Advent)

There is also a further layer that helps explain why the matter was so delicate. There was a traditional connection between this observance of the 14th of Nisan and St. John the Apostle. The churches of Asia did not defend their custom as a novelty or local preference. Ancient testimony reports that they appealed to earlier saints and bishops of their region and associated their practice with the apostolic tradition linked to St. John. This does not mean that every detail can now be reconstructed with certainty, but it does show that the Quartodeciman custom was regarded by its defenders as something ancient, venerable, and received. (New Advent)

This is what makes the meeting between St. Polycarp and St. Anicetus so moving. Polycarp himself stood close to the apostolic age and was traditionally linked to St. John. When he came to Rome, he and Anicetus did not achieve one practice. Yet they did not rend the peace of Christ. They did not treat one another as strangers. They remained in communion. This scene has an abiding beauty because it shows that serious disagreement about liturgical observance need not lead at once to bitterness or rupture. The pope of Rome held fast to the Roman custom. The aged bishop from Asia held fast to what he had received. Yet charity still ruled their meeting. (New Advent)

At this point it helps to understand the calendars themselves more clearly, because modern discussions of Easter often involve terms that can seem bewildering. St. Anicetus was not familiar with the Gregorian calendar at all. He lived in the second century, and the civil calendar of the Roman world in his day was the Julian calendar. The Easter question of his age therefore did not concern a choice between Julian and Gregorian reckoning. It concerned the relation between the Christian Pasch and the Jewish Passover, between the 14th of Nisan and the Sunday of the Resurrection. Still, the fact that he lived under the Julian calendar does matter, because it reminds us that Christians were already trying to situate sacred time within the civil order of the empire while also remaining faithful to the biblical history of salvation. (Encyclopedia Britannica)

The Julian calendar had been introduced by Julius Caesar, taking effect in 45 B.C. It was a reform of the older Roman system and was based on a solar year of 365 days with an additional day added every fourth year. This was a great improvement for civil life, and for centuries it served the Roman world well. Yet it was not perfectly precise. The Julian year was slightly too long, by about 11 minutes and 14 seconds. That seems trivial, but over centuries the error accumulated, and the calendar slowly drifted away from the actual seasons. (Encyclopedia Britannica)

This gradual drift is the reason the Gregorian calendar was eventually introduced. By the sixteenth century, the vernal equinox was no longer occurring where it had been reckoned in the Church’s paschal calculations. Since Easter is tied to the relationship of spring, the moon, and Sunday, this was not merely an astronomical problem. It affected the Church’s determination of her greatest feast. So Pope Gregory XIII introduced the Gregorian reform in 1582. The reform corrected the accumulated error by dropping ten days from the calendar and by refining the leap-year rule: century years would not automatically be leap years unless divisible by 400. In this way, the Gregorian calendar kept more accurate step with the solar year. (Encyclopedia Britannica)

So the difference between the two calendars may be stated simply. The Julian calendar adds a leap day every four years without exception. The Gregorian calendar keeps that basic pattern, but corrects it at the century marks. Thus 1700, 1800, and 1900 were leap years in the Julian system but not in the Gregorian, while 2000 was a leap year in both. Because of this, the two calendars slowly separate. At present, the Julian calendar stands 13 days behind the Gregorian calendar. (Encyclopedia Britannica)

Why, then, do many Orthodox Christians still follow the Julian calendar or the Julian paschalion for Pascha? The answer is not that they are unaware of the astronomical difference. Rather, many Orthodox churches have wished to preserve the older inherited paschal reckoning, which they connect to the canonical and liturgical order received from the ancient Church, especially from the age after Nicaea. There has also long been a reluctance to adopt a reform that came from Rome in 1582, particularly given the painful history of East-West division. In many Orthodox communities, the issue is therefore not simply scientific but also ecclesial, liturgical, and historical. (Greek Orthodox Archdiocese of America)

A further nuance is important. Not all Orthodox churches handle the matter in precisely the same way. Some use the Revised Julian calendar or Gregorian-style dates for many fixed feasts, while still calculating Pascha according to the traditional Julian paschalion. This means the heart of the matter is often not merely which civil calendar one hangs on the wall, but how the Church determines the feast of feasts, the yearly celebration of the Lord’s Resurrection. (Greek Orthodox Archdiocese of America)

Seen in this light, St. Anicetus becomes very close to us. He lived long before the Gregorian reform, long before the present East-West calendar divide took the form we know today, yet he stood near the beginning of a question that still troubles Christians. His age knew the Roman Julian calendar, but the Church also had to reckon with the biblical and Jewish setting of Christ’s Passion. Nisan belonged to a lunisolar sacred calendar. Julian and Gregorian are solar civil calendars. The old debate was really about how the Church should keep sacred time in a way that honored both the scriptural roots of the Passion and the glory of the Resurrection. (Encyclopedia Britannica)

There is a lesson here that reaches beyond chronology. We modern people are accustomed to thinking of time as something mechanical. We think in deadlines, appointments, fiscal years, school calendars, and quarterly reports. The early Christians, by contrast, lived much more consciously within sacred time. Nisan was not just a month. It was the season of deliverance. Sunday was not merely the end of a week. It was the day of the Risen Lord. The dispute in the age of Anicetus was therefore not only about counting. It was about how the mighty works of God should shape the rhythm of Christian memory. (Encyclopedia Britannica)

This is why St. Anicetus still speaks to the Church now. Christians today still know the sorrow of divided Easter observance. The old Quartodeciman controversy is not the same as the present calendar problem, yet the wound is related. The faithful still ask, in one form or another, how the Church can proclaim with one voice the Resurrection of Christ. And St. Anicetus still answers, not with a technical formula, but with a manner of soul. He teaches us to hold fast to what has been received, to take liturgical questions seriously because Christ is serious, and yet to refuse the temptation to let zeal become contempt. (New Advent)

What should we remember on his feast, then? We should remember a pope who understood that holy things matter. We should remember a shepherd who knew that the mysteries of Christ are too precious to be treated carelessly. We should remember a man who lived in the Julian world of ancient Rome, yet knew that the Church could not simply measure her life by the empire’s civil clock. She had to mark time according to the works of God. Above all, we should remember that when a grave dispute arose, he did not abandon peace. In that lies much of his sanctity.

And perhaps this becomes a quiet examination for us. What governs our days? Is time for us only a chain of errands, anxieties, and passing demands? Or does the life of Christ truly order our weeks and seasons? Do we allow Lent, Easter, Sunday, feast days, and the great mysteries of salvation to impress themselves upon our lives, or do we merely glance at them while living by another master calendar altogether? St. Anicetus reminds us that time itself can be consecrated. The Church does not merely fill the year with commemorations. She teaches us to dwell within the acts of God.

So on April 17, let us remember St. Anicetus as a man of the Church’s springtime: a pope who helped preserve peace when the Church’s greatest feast might have become a cause of deeper division; a witness to the truth that sacred time matters because Christ has entered time; a shepherd who teaches that conviction and charity must never be enemies. Let us remember that Nisan was the month of Passover, belonging to a lunisolar sacred calendar; that Julius Caesar gave the Roman world the Julian calendar; that Pope Gregory XIII introduced the Gregorian reform in 1582 to correct drift and preserve the proper reckoning of Easter; and that many Orthodox Christians still retain the older paschal reckoning out of reverence for inherited liturgical tradition. Yet beyond all these facts, let us remember the deeper thing: St. Anicetus teaches the Church how to walk when holy things are at stake, with reverence, with firmness, and with peace. (Encyclopedia Britannica)

Lord Jesus Christ, true Paschal Lamb,

who didst sanctify time by Thy Passion and Resurrection,

teach us to number our days in the light of Thy mysteries.

Grant to Thy Church unity in worship, patience in trial,

and charity in all things.

And through the intercession of St. Anicetus,

give us the grace to hold fast to what is holy

without losing the peace that comes from Thee.

Amen.
