The Saint of the Day for July 27 is St. Panteleon.
St. Panteleon, whose feast we celebrate on July 27, is the patron saint of bachelors and physicians.
As lifelong layperson, he was the physician for emperor Maximian. At one point in his life he had abandoned his faith, but he eventually returned to the Church, and gave his fortune to the poor, providing them medical treatment without charge. Some of his cures were accomplished by prayer.
Other physicians eventually denounced him to the anti-Christian authorities. At his trial, he offered a contest between himself and the pagan priests. He challenged the pagan priests to heal a paralyzed man with their prayers, but they were unable. Panteleon cured the man by simply mentioning the name of Jesus. As a result, many of those who witnessed the miracle converted to Christianity.
However, the authorities remained resolute in trying to get him to denounce his faith with bribes, threats and torture, but they did not succeed. He was then nailed to a tree and beheaded in c.305.
