Oh glorious martyrs of Christ, Saints Cosmas and Damian, you gave your lives for the love of God, benefiting your fellow man, and crowning your martyrdom with an open and loyal profession of your faith. You taught us to love God above all things, and to love our fellow man as ourselves, professing always, and without fear, the religion of Jesus. Augmenting amongst the faithful populace many miracles, you are glorious indeed. Through your intercession, which brings about deliverance of these miracles, we pray to you for your aid in all things. May your patronage never be far from us in the illness of our body and soul. Oh great protectors, Saints Cosmas & Damian, assist us with your love and free us from all evils. Amen.
The only thing we know about Sts. Cosmas and Damian is that they suffered martyrdom in Syria during the Roman persecution of Diocletian, around 303 A.D. Tradition says they were twin brothers and medical doctors, and have been honored since the 6th century. These brothers never charged a fee for their medical services. Their names are in the Roman Canon of the Mass.
