Romans 12.4-5, 15-21 (Epistle)

4For as we have many members in one body, and all members have not the same office: 5So we, being many, are one body in Christ, and every one members one of another. 15Rejoice with them that do rejoice, and weep with them that weep. 16Be of the same mind one toward another. Mind not high things, but condescend to men of low estate. Be not wise in your own conceits. 17Recompense to no man evil for evil. Provide things honest in the sight of all men. 18If it be possible, as much as lieth in you, live peaceably with all men. 19Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord. 20Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head. 21Be not overcome of evil, but overcome evil with good.

Matthew 12.9-13 (Gospel)

9And when he was departed thence, he went into their synagogue:

10And, behold, there was a man which had his hand withered. And they asked him, saying, Is it lawful to heal on the sabbath days? that they might accuse him. 11And he said unto them, What man shall there be among you, that shall have one sheep, and if it fall into a pit on the sabbath day, will he not lay hold on it, and lift it out? 12How much then is a man better than a sheep? Wherefore it is lawful to do well on the sabbath days. 13Then saith he to the man, Stretch forth thine hand. And he stretched it forth; and it was restored whole, like as the other.

Holy and Wonderworking Unmercenaries Cosmas and Damian, martyrs at Rome (284)

There are three pairs of Unmercenary Physicians named Cosmas and Damian. The two commemorated today were brothers from Rome. Though they inherited great wealth, they gave most of it to the poor and needy, only setting aside enough for themselves to devote their lives to the service of Christ. As Christian physicians, they freely performed their healing services for men and for beasts, asking the healed only to believe in Christ in thanks for their healing. They ended their lives in martyrdom. According to the Prologue, they were summoned before the Emperor Galerius, who interrogated them and commanded them to worship the gods. The brothers refused to do so, but to show the truth of the Christian faith, they healed the Emperor of a grave infirmity. At this he proclaimed the truth of Christianity and released them. But a doctor and a former teacher who envied their reputation lured them into the countryside on the pretext of collecting herbs, then killed them.
