Saint Panteleimon is a Christian martyr and healer, celebrated for his compassion and miraculous abilities. He lived in the 3rd century in Nicomedia, where he practiced medicine and helped the sick, often without charge. His name means "all-merciful," reflecting his dedication to helping others. He is venerated in both the Eastern Orthodox and Roman Catholic traditions, with his feast day observed on July 27. Many churches are dedicated to him, and he is often depicted in icons holding a medicine box and a cross, symbolizing his dual role as a healer and a martyr for his faith.
