Kosmas and Damian of Rome
July 1, Martyr, Κοσμάς και Δαμιανός
Sts. Kosmas and Damian of Rome were brothers and physicians of the third century who healed the sick freely in the name of Christ, accepting no payment, for which they are counted among the Holy Unmercenaries. Their charity and their faith drew many to the Church, and according to tradition they ended their lives as martyrs.

Kosmas and Damian (Asian)
November 1, Saint, Κοσμάς και Δαμιανός
Saints Kosmas and Damian of Asia Minor were brothers and physicians, raised in the faith by their pious mother Theodota. They treated the sick without ever accepting payment, asking only that those they healed believe in Christ, and for this the Church calls them Unmercenaries. They reposed in peace after lives given wholly to God and neighbor.
