Holiday on September 18, 2026: Honoring the Martyrs Sophia and Irina
On September 18 according to the New Julian calendar, the faithful commemorate the holy martyrs Sophia and Irene of Egypt, who, according to church tradition, were killed for their Christian faith in Alexandria in the 3rd century. On this same day, the martyr Castor of Alexandria and other saints are also commemorated, but Sophia and Irene hold a special place in this commemoration. According to the Julian calendar, the date of their commemoration falls on October 1.
The day of remembrance for the martyrs Sophia and Irene is observed annually on September 18 according to the New Julian calendar. In church calendars that follow the Old Style, this date corresponds to October 1 on the Gregorian calendar. In 2026, September 18 falls on a Friday. Church calendars explicitly list the commemoration of the martyrs Sophia and Irene of Egypt for this day.
These are Sophia and Irene of Egypt, not the martyr Sophia of Rome and her daughters Faith, Hope, and Love. The commemoration of Sophia of Rome and her three daughters is observed on September 17 according to the New Style calendar, that is, one day before the commemoration of Sophia and Irene. Because both are named Sophia, these two church dates are often confused. Therefore, in materials about September 18, it is important to specify that the reference is specifically to the martyrs from Egypt. In 2026, the commemoration falls on a Friday; therefore, in the Orthodox calendar, it is also a day of fasting. The Greek Orthodox Archdiocese of America prescribes strict fasting for September 18, 2026—no meat, fish, oil, dairy products, or eggs. Specific fasting rules may depend on church tradition and an individual’s personal circumstances.
Who Were Sophia and Irene?
Little detailed information has survived about the lives of Sophia and Irene. Church tradition identifies them as martyrs who suffered for the Christian faith in Egypt. Their memory is associated with Alexandria—one of the largest cities of the ancient world and an important center of early Christianity. It was there, according to church tradition, that Sophia, together with Irene, suffered a martyr’s death.
In the Orthodox calendar, they are referred to as the martyrs Sophia and Irene of Egypt. The Church commemorates them together, although some calendars specify that Sophia suffered alongside Irene and Castor. Sources reveal very little about the specific circumstances of their lives. Therefore, one should not add details to their story that are not confirmed by church tradition.
It is known that their martyrdom is dated to the 3rd century. This was a period when Christian communities in various parts of the Roman Empire were subject to persecution. Christians who refused to renounce their faith or participate in pagan rituals could fall victim to persecution. It is precisely within this historical context that church tradition tells the story of the martyrs Sophia and Irina.
Why Are They Called Martyrs?
In Christian tradition, the word “martyr” refers to a person who suffered or died for their faith. In the case of Sophia and Irene, these are precisely the people who, according to church tradition, did not renounce Christianity even in the face of death. That is why the Church does not merely mention their names but honors them as examples of steadfastness and faithfulness. In liturgical tradition, martyrs are regarded as people who placed their faith above their fear of persecution.
September 18 features a special troparion dedicated to the martyrs Sophia, Irene, and Castor. It states that the saints received “imperishable crowns” from God for their sufferings. This is not a description of a historical event in the modern documentary sense, but rather part of liturgical language and the Church’s veneration of martyrs. Through such texts, the Church conveys the central message of this day—the remembrance of people who remained faithful to their faith. To modern readers, this story may seem very simple. It serves as a reminder of the power of conviction and of the fact that, for the early Christians, faith was not merely a personal feeling but a way of life. People could lose their possessions, their freedom, and even their lives because of their convictions. That is why the commemoration of the martyrs holds an important place in the church calendar.
Alexandria and Early Christianity
The story of Sophia and Irene is connected to Alexandria. In the early centuries of Christianity, this city was one of the most important cultural and religious centers of the Mediterranean. There was a large Christian community there, and local theologians played a significant role in shaping early Christian thought. Therefore, references to the martyrs of Alexandria occupy a prominent place in church tradition.
According to the Church’s hagiography, it was in Alexandria that Sophia suffered a martyr’s death alongside Irina and Castor. At the same time, contemporary sources do not provide a detailed account of their lives prior to their martyrdom. For this reason, the history of the saints must be presented with caution, without fabricated details about their age, origin, family, or the specific circumstances of their execution, unless these are confirmed by sources. At that time, Alexandria was a large, multinational city. Various cultures, religions, and traditions intersected there. Christianity was gradually spreading among the population but had not yet become the dominant religion of the empire. That is why the stories of the early Christian martyrs are associated with a period when the new religion was developing under difficult conditions.
Why Does the Church Commemorate Sophia and Irene Together?
Sophia and Irene share a common feast day and are commemorated in the church calendars as the Egyptian Martyrs. Along with them, Castor of Alexandria is commemorated on this day. The Greek Orthodox liturgical calendar explicitly lists September 18 as the commemoration of the “Holy Martyrs Sophia and Irene,” as well as, separately, the martyr Ariadne and the martyr Castor.
Being commemorated together does not mean that Sophia and Irene were related or lived in the same family. The church calendar simply groups saints by the day they are honored. This practice is common among early Christian martyrs. A single day may be dedicated to several people who suffered for their faith under different circumstances. During the divine service, their names are mentioned as examples of steadfastness. The Church reminds us that the martyrs did not respond to persecution with violence but remained faithful to their convictions. That is why the day commemorating them is spiritual in nature, rather than entertainment-oriented.
How This Day Is Observed
For believers, September 18 is first and foremost a day of prayer and remembrance of the saints. Divine services are held in churches, during which Eumenia of Gortyna, the martyr Ariadne, Sophia, Irina, Castor, and other saints of this day are commemorated. Certain liturgical texts are dedicated specifically to the martyrs Sophia and Irina. People may come to church, light a candle, pray for the health of their loved ones, and remember the deceased. It is important to note that a candle in and of itself is not a “talisman” and does not guarantee that a wish will be granted. In the church tradition, prayer and a person’s inner appeal to God are of primary importance.
On this day, you can also do a good deed. For example, you can support someone who is alone, help a family in need, or make a donation to charity. This approach is consistent with the general Christian understanding of the commemoration of the saints. The Day of the Martyrs can be observed not only in church but also in the peaceful setting of one’s family.
What You Can and Shouldn’t Do on September 18
The Church does not establish a separate, universal list of household prohibitions specifically because of the commemoration of Sophia and Irene. Therefore, statements such as “you cannot do laundry,” “you cannot clean,” “you cannot work,” or “you cannot pick up scissors” should not be presented as church rules. These may be folk beliefs that emerged much later and do not carry the same status as church precepts.
However, September 18, 2026, falls on a Friday, and therefore, in the Orthodox tradition, it is a day of fasting. The Greek Orthodox Archdiocese of America specifies strict fasting for this date. This involves abstaining from meat, fish, oil, dairy products, and eggs. At the same time, people can consult with their priest regarding fasting, especially if they have health issues, engage in heavy physical labor, or face other circumstances. Fasting should not be reduced to merely a list of foods. In the church tradition, it is meant to be a time of self-restraint, prayer, and reflection on one’s own behavior.
Are there any folk traditions associated with this day?
Over time, folk customs have developed around many church holidays. People associated specific days on the calendar with changes in the weather, the harvest, fieldwork, and preparations for winter. However, specifically regarding Sophia and Irene on September 18, there is little reliable historical evidence of ancient Ukrainian folk rituals. Therefore, one should not attribute fictional traditions to this day or present modern everyday superstitions as ancient church customs. It is much more accurate to say that the main tradition remains the Church’s commemoration of the martyrs. This involves prayer, participation in the divine service, and remembrance of their heroic deeds.
In some modern calendars, one may come across various superstitions and taboos associated with this date. However, these do not form part of official church doctrine. If such information is used in popular publications, it should be clearly identified as folk beliefs.
Interesting Facts About Sophia and Irina
Sophia and Irina are not the saints honored on September 17. On September 17, the Church commemorates the martyr Sophia and her three daughters—Faith, Hope, and Love. On September 18, the calendar mentions other martyrs—Sophia and Irina of Egypt. Due to the proximity of the dates and the shared name “Sophia,” these commemorations are often confused.
Their commemoration is associated with Egypt. Church sources indicate that Sophia suffered alongside Irina and Castor in Alexandria. That is why the calendar specifies “of Egypt” in their names.
They are dated to the 3rd century. This is the period indicated by Orthodox calendars and hagiographic sources. This means that their martyrdom is associated with the early history of Christianity, when Christian communities were still living within the pagan Roman Empire.
Castor is commemorated alongside them. In church sources, he is referred to as the Martyr of Alexandria. In the troparion for September 18, Sophia, Irene, and Castor are mentioned together as holy martyrs.
September 18 is also the day of remembrance for Eumenes of Gortyna. He was a bishop in Crete and is known in the Church tradition as a miracle-worker. The martyr Ariadne of Phrygia is also commemorated on this day. Thus, this calendar date unites the commemoration of several saints at once.
What This Day Means Today
The commemoration of the martyrs Sophia and Irene is, first and foremost, a church holiday dedicated to those who, according to Christian tradition, died for their faith. Their story dates back to the early period of Christianity and is associated with Alexandria in Egypt. Although few details about the saints’ lives have survived, the Church has continued to commemorate them in its services over the centuries.

It is a good tradition to help those in need or simply do a good deed for someone. Most importantly, do not confuse this date with September 17, when Saint Sophia of Rome and her daughters Faith, Hope, and Love are honored.
