Life and Ministry
According to the tradition recorded in the synaxaria, Cosmas and Damian were born at Rome and trained as physicians. They treated the sick without charging a fee, a practice that earned them the title of unmercenaries. The accounts relate that when they healed, they told their patients, in effect, that the cure came not by their own power but by the power of Christ, the true God; their charity and confession are said to have converted many.
The lives relate that the Roman authorities arrested the brothers for their Christian faith and their refusal to offer pagan sacrifice. By tradition, when they were brought before the emperor Carinus, they openly professed Christ; the emperor was afflicted in answer to their witness and afterward healed through their prayers when he promised to turn to the faith, and they were released.
