Saint John Chrysostom, famous preacher and Archbishop of Constantinople, faced persecution and exile due to his courageous defense of Christian truth and reform. In spite of severe challenges, such as being exiled to distant areas and enduring cold and animosity, he stayed resolute in his faith and care for his flock. He passed away in exile in 407, and years later, his relics were venerated in Constantinople, reinforcing his enduring legacy as an exemplar of holiness and bravery.
