September 2 Orthodox Feast: Sts. Anthony and Theodosius of the Caves — What Saint Day Is Today

If you are searching what saint day is today for September 2, 2026, the Orthodox Church of Ukraine especially commemorates Sts. Anthony and Theodosius of the Kyiv Caves, two foundational figures in the monastic tradition of the Kyiv-Pechersk Lavra. The calendar also remembers the martyr Mamas, his parents Theodotus and Rufina, St. John the Faster, and a large group of martyrs of Nicomedia.

September 2, 2026 falls on a Wednesday, so the date also coincides with the normal weekly Orthodox fast. The feast itself does not prohibit ordinary work or household tasks.

What saint day is today: What is today's church holiday, September 2, 2026 according to the new calendar

Under the fixed-feast calendar used by the Orthodox Church of Ukraine, September 2 includes:

• Sts. Anthony and Theodosius of the Kyiv Caves;

• the martyr Mamas;

• his parents, Theodotus and Rufina;

• St. John the Faster, Patriarch of Constantinople;

• the 3,628 martyrs associated with Nicomedia.

The date has particular significance in Ukraine because Anthony and Theodosius are closely connected with the formation of the Kyiv-Pechersk monastic tradition.

The Orthodox Church of Ukraine uses the New Julian calendar for fixed feasts. Older sources using the Julian or "old-style" calendar can show the same commemorations on a different civil date.

Who is Antoniy Kyiv-Pechersky

St. Anthony of the Kyiv Caves is regarded as one of the founders of monastic life at what became the Kyiv-Pechersk Lavra. He was born in Liubech and, according to church tradition, spent time on Mount Athos before returning to the lands of Kyivan Rus.

He settled in a cave near Kyiv and lived a life centered on prayer, fasting, and solitude. Other men seeking the monastic life gradually gathered around him, forming a community.

Anthony's importance is not limited to one monastery building. His example helped establish a monastic tradition that became central to the religious and cultural history of medieval Kyiv and later Ukrainian Christianity.

Who is Feodosius of Kyiv-Pechersky

St. Theodosius of the Kyiv Caves became one of the main organizers of the early monastery. While Anthony is associated with the beginnings of the cave community, Theodosius is remembered for giving it a stronger communal structure.

Under his leadership, the monastery adopted a common rule of life emphasizing prayer, obedience, work, shared responsibility, and care for people in need. He helped transform a small ascetic community into an organized monastery with lasting influence.

Anthony and Theodosius are therefore often commemorated together. Their roles were different but complementary: one represents the founding ascetic impulse, while the other represents the development of stable communal monastic life.

Who is the martyr Mamant

Mamas, sometimes rendered Mamant in Slavic calendars, is an early Christian martyr associated with Cappadocia. Church tradition places his life in the third century during periods of persecution of Christians in the Roman Empire.

He was born to Christian parents and is remembered for openly professing his faith. Accounts of his life became popular in Eastern Christian tradition, and churches dedicated to him appeared in several regions of the Byzantine world.

On September 2, his memory appears together with that of his parents, Theodotus and Rufina.

Who are Feodotus and Rufina

Theodotus and Rufina are remembered as the Christian parents of St. Mamas. Church tradition says they suffered because of their faith during persecution, leaving their son to be raised after their deaths.

Their commemoration illustrates a pattern common in early Christian calendars: family members who shared the same faith and period of persecution may be remembered together even when one of them became more widely known.

In English, the names may appear in slightly different transliterations, but the saints are the same figures found in the Ukrainian and Greek traditions.

Who is Ioan Posnyk

Ioan Posnyk is better known in English as St. John the Faster, Patriarch of Constantinople. He lived in the sixth century and became known for personal austerity, pastoral discipline, and church leadership.

The title "the Faster" refers to his reputation for strict fasting and ascetic life. He served as Patriarch of Constantinople and is remembered as a church leader rather than as a martyr.

His commemoration adds a later Byzantine figure to a day otherwise strongly associated with the Kyiv Caves and early Christian martyrs.

Who are the 3628 martyrs of Nicomedia?

The calendar also commemorates a very large group of martyrs associated with Nicomedia, an important city of the Roman Empire where Christians faced severe persecution in the early fourth century.

The number recorded in church tradition emphasizes the scale of persecution remembered by the community. Modern readers do not need to focus on violent details; the church commemoration centers on steadfastness in faith under pressure.

Their memory places September 2 within the wider tradition of collective martyr commemorations found throughout the Orthodox calendar.

The September 2 list can look unusually long because an Orthodox calendar often combines several kinds of commemoration on the same civil date. Anthony and Theodosius are connected with the Kyiv-Pechersk monastic tradition, while Mamant belongs to the early Christian martyr tradition. John the Faster represents the later Byzantine church, and the large group from Nicomedia reflects collective commemorations preserved in church tradition.

That mix is useful when reading a church calendar: the first names in a daily list are not necessarily the only saints honored, and the date is not a single-person "name day" in the modern sense. A parish service may give particular liturgical emphasis to one commemoration while still listing the others in the calendar.

For readers comparing older publications, the date can also appear different because the Orthodox Church of Ukraine uses the New Julian calendar for fixed commemorations. Older Julian-calendar schedules place many of the same fixed feasts 13 days later on the civil calendar. The safest approach is to check which calendar a source is using before concluding that two lists contradict each other.

One more practical distinction is worth keeping in mind. A saint listed on September 2 does not automatically mean that everyone with a similar first name celebrates a name day on that date. Naming traditions differ by family, parish, and the saint after whom a person was actually named. For a personal name-day date, the relevant patron saint matters more than a simple name match in a daily calendar.

Is there a fast on September 2, 2026

Yes. September 2, 2026 is a Wednesday, one of the normal weekly fast days in Orthodox practice unless a specific calendar exception applies.

The feast of Anthony and Theodosius does not itself create the fast; the weekly Wednesday rule is the reason. The exact form of fasting can vary by church tradition, personal circumstances, age, health, and pastoral guidance.

People with medical needs should not treat internet fasting lists as medical instructions. Questions about a personal fasting rule are better discussed with a priest and, where health is involved, a healthcare professional.

What is important to know about the church holiday of September 2, 2026
