Sources: 38. Developments: 3. October 6 marks the feast day of Saint Thomas the Apostle in the Orthodox Church. Tradition holds that the Apostle, known as ‘the Twin’, initially doubted the Resurrection until he inspected the wounds of Christ. Following Pentecost, he is said to have traveled to regions including Persia, Media, and India, where he is credited with establishing Christian communities before his martyrdom. In addition to being a patron feast for individuals named Thomas and its derivatives, the day is observed in Bulgaria as a professional holiday for architects, builders, and masons. In many Eastern European and Mediterranean cultures, the date also serves as a name day for individuals named Thomas, Tom, or Thomai. In the Balkan region, the day is known in folk tradition as ‘Tomindan’. In Serbia, it is celebrated as a patronal feast (krsna slava) for many families and a guild feast (esnafska slava) for trades such as carpenters, masons, and blacksmiths, reflecting his role as a protector of woodworkers. Regional customs include staying indoors to honor the saint, often expressed by the proverb ‘Saint Thomas, sit at home’, and associations with protection against wolves and seasonal agricultural transitions. Recent observations emphasize his connection to the Dormition of the Mother of God, as tradition holds he arrived late to her funeral only to find her tomb empty. In certain areas, prayers are also offered to him to request rain during periods of drought. ## Claims - The Orthodox Church celebrates the feast day of Saint Thomas the Apostle on October 6.
