Today, February 15, the Orthodox Church honors the memory of Saint Onesimus the Apostle, a figure closely associated with the Apostle Paul and exemplifying repentance and transformation. Originally, Onesimus was a slave of Philemon, but after escaping and meeting Apostle Paul in Rome, he converted to Christianity, fundamentally changing his life. Paul refers to him as 'my son', indicating their deep spiritual bond, and upon returning to Philemon, he did so not as a slave, but as a brother in Christ. Ultimately, Onesimus served as a bishop and became a martyr for his faith.

The calendar also honors other saints today, such as Saint Eusebius, noted for his ascetic life and dedication to prayer, and Saint Maior the Martyr, who boldly confessed Christ and endured torture. Additionally, it recognizes Saint Anthimos the Vagian from Chios, a contemporary figure known for his humility, discernment, and love for the people, as well as Saint John of Koulakio, the New Martyr. Each of these saints represents different aspects of faith and devotion in the Orthodox tradition, which underscores the Church's rich tapestry of history and spiritual legacy.

This observance is significant for the Orthodox community as it reinforces the values of forgiveness, brotherhood, and steadfast faith that these saints embodied. It serves as a reminder of the transformative power of faith, encouraging believers to aspire to the ideals exemplified by the saints, thus enriching their spiritual journey within the church and beyond.
