Cosmas and Damian were unmercenaries physicians and miracle-workers. They were brothers both in the flesh and in the spirit, born somewhere in Asia Minor of a pagan father and a Christian mother. After their father’s death, their mother Theodote devoted all her time and effort to educating her sons and raising them as true Christians. God helped her, and her sons matured as sweet fruit and luminaries of the world.
They were learned in the art of medicine and ministered to the sick without payment, not so much with medicine as by the name of the Lord Jesus Christ. They were called “unmercenary physicians,” that is, unpaid physicians, for they healed freely and thus fulfilled the commandment of Christ: Freely ye have received, freely give (Matthew 10:8).
So careful were they in healing men free of charge that Cosmas became very angry with his brother Damian because he accepted three eggs from a woman, Palladia, and ordered that he not be buried alongside his brother Damian after his death. In fact, St. Damian did not accept these three eggs as a reward for healing the ailing Palladia, but rather because she adjured him in the name of the Most-holy Trinity to accept these three eggs.
Nevertheless, after their death in the town of Fereman, they were buried together according to a revelation from God. The holy brothers were great miracle-workers both during their life and after their death. Thus, the Lord glorified forever the miracle-working of those who glorified Him on earth by their faith, purity and mercy.
