On February 17, 2026, the Orthodox Church commemorates the memory of Saint Theodore the Tyro, one of the most revered saints from the early Christian centuries. This date also marks the Tuesday of the Cheese-Fare Week, within the lenten season leading to Great Lent. Saint Theodore, who was a soldier in the Roman army, is celebrated for his steadfast refusal to sacrifice to idols, boldly professing his faith in Christ, which ultimately led him to endure severe tortures and martyrdom by fire.

The church particularly honors Saint Theodore's memory on the first Saturday of Great Lent, recalling the miracle of the collyboi, when he appeared to protect Christians from defiled food. This commemoration reflects the deep-rooted traditions and spiritual significance of Lent, a time of reflection and penitence for Orthodox Christians. In addition to Saint Theodore, the calendar honors Saint Mariamna, the Equal-to-the-Apostles sister of Saint Philip the Apostle, who dedicated her life to spreading the Gospel.

These celebrations highlight the importance of faith and sacrifice in the Christian tradition, emphasizing the lives of those who demonstrated great devotion and courage. The observances not only serve to remember these saints but also to inspire believers during the solemn season of Lent, fostering a greater sense of community and shared beliefs in the Orthodox Christian faith.
