They used their medical skills to spread the Christian faith among their patients in third-century Syria. They were martyred during the persecution of Diocletian along with their three brothers.
The vocation of Sts. Cosmas and Damian reminds us that holiness is not the exclusive domain of monks and nuns but the universal call of every baptized Christian.

Sts. Cosmas and Damian is honored as the patron saint of Physicians, surgeons, pharmacists, dentists, barbers. The designation of patron saints is a beautiful expression of the Catholic doctrine of the Communion of Saints — the belief that the saints in heaven are not distant figures from the past but active intercessors who accompany us in our earthly journey.
Those who work in or are associated with Physicians have traditionally invoked Sts. Cosmas and Damian's intercession for protection, guidance, and grace in their particular circumstances. The patronage of Sts. Cosmas and Damian is grounded in the specific details of Damian's life and ministry, which created a lasting bond between this saint and those who share similar callings or needs.
