Unmercenaries and wonderworkers, they were brothers in the flesh and in the spirit, born somewhere in Asia of a pagan father and a Christian mother. After their father"s death, their mother Theodota devoted all her time and energy to the bringing-up of her sons as true Christians. God helped her, and her sons grew as two choice fruits and as two holy lamps. They were skilled in medicine and ministered to the sick without payment, and so fulfilled Christ"s command: "Freely have ye received; freely give" (Matt. 10: 8). They were so strict in their unpaid ministry to men that Cosmas became greatly enraged with his brother Damian when he took three eggs from a woman, Palladia, and gave orders that, after his death, he should not be buried with his brother. In fact, holy Damian had not taken those eggs as a reward for healing Palladia"s sickness, but because she had sworn by the Most Holy Trinity that he should have them. However, after their death in Fereman, they were buried together in obedience to a revelation from God. These two holy brothers were great wonderworkers both during their lifetime and after their death. A farm Tabourer, on lying down to sleep at one time, was attacked by a snake, which entwined itself around his mouth and stomach. This poor man would have breathed his last in the greatest torment had he not at the last moment invoked the help of Saints Cosmas and Damian. Thus the Lord glorified forever by miracles those who glorified Him here on earth by their faith, purity and mercy.
