1 Corinthians 9.13-18 (Epistle)

13Do ye not know that they which minister about holy things live of the things of the temple? and they which wait at the altar are partakers with the altar? 14Even so hath the Lord ordained that they which preach the gospel should live of the gospel. 15But I have used none of these things: neither have I written these things, that it should be so done unto me: for it were better for me to die, than that any man should make my glorying void. 16For though I preach the gospel, I have nothing to glory of: for necessity is laid upon me; yea, woe is unto me, if I preach not the gospel! 17For if I do this thing willingly, I have a reward: but if against my will, a dispensation of the gospel is committed unto me. 18What is my reward then? Verily that, when I preach the gospel, I may make the gospel of Christ without charge, that I abuse not my power in the gospel.

Matthew 16.1-6 (Gospel)

1The Pharisees also with the Sadducees came, and tempting desired him that he would shew them a sign from heaven. 2He answered and said unto them, When it is evening, ye say, It will be fair weather: for the sky is red. 3And in the morning, It will be foul weather to day: for the sky is red and lowring. O ye hypocrites, ye can discern the face of the sky; but can ye not discern the signs of the times? 4A wicked and adulterous generation seeketh after a sign; and there shall no sign be given unto it, but the sign of the prophet Jonas. And he left them, and departed. 5And when his disciples were come to the other side, they had forgotten to take bread.

6Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees.

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.
