Galatians 3.15-22 (Epistle)

15Brothers, speaking of human terms, though it is only a man’s covenant, yet when it has been confirmed, no one makes it void or adds to it. 16Now the promises were spoken to Abraham and to his offspring. He doesn’t say, “To descendants”, as of many, but as of one, “To your offspring”, which is Christ. 17Now I say this: A covenant confirmed beforehand by God in Christ, the law, which came four hundred thirty years after, does not annul, so as to make the promise of no effect. 18For if the inheritance is of the law, it is no more of promise; but God has granted it to Abraham by promise.

19Then why is there the law? It was added because of transgressions, until the offspring should come to whom the promise has been made. It was ordained through angels by the hand of a mediator. 20Now a mediator is not between one, but God is one.

21Is the law then against the promises of God? Certainly not! For if there had been a law given which could make alive, most certainly righteousness would have been of the law. 22But the Scripture imprisoned all things under sin, that the promise by faith in Jesus Christ might be given to those who believe.

Mark 6.7-13 (Gospel)

7He called to himself the twelve, and began to send them out two by two; and he gave them authority over the unclean spirits. 8He commanded them that they should take nothing for their journey, except a staff only: no bread, no wallet, no money in their purse, 9but to wear sandals, and not put on two tunics. 10He said to them, “Wherever you enter into a house, stay there until you depart from there. 11Whoever will not receive you nor hear you, as you depart from there, shake off the dust that is under your feet for a testimony against them. Assuredly, I tell you, it will be more tolerable for Sodom and Gomorrah in the day of judgment than for that city!”

12They went out and preached that people should repent. 13They cast out many demons, and anointed many with oil who were sick and healed them.

Apostle Thaddeus of the Seventy

He was by birth a Jew from Edessa; it was he who instructed king Avgar in the Faith and baptised him (see August 16). According to Eusebius he is not the Thaddeus who was one of the Twelve (Mt 10:3), but was one of the Seventy. After Christ’s Resurrection, he preached the Gospel in Mesopotamia and ended his life in martyrdom.

Holy Martyrs Bassa and her sons Theognis, Agapios, and Pistis (4th c.)

“Bassa was the wife of a pagan priest, but she was secretly a Christian and brought her sons up in a Christian spirit. Her husband hated her for her faith, and handed her over to the judge for torture, together with her sons. After harsh torture, her sons were beheaded (it is thought, in Edessa in Macedonia). Bassa was filled with joy to see her sons thus gloriously finish their martyr’s course for Christ, and herself went with yet greater desire from torture to torture. When she was thrown into the sea, angels appeared to her and took her to an island in the Sea of Marmara, where she was slain with the sword under Maximian. Thus holy Bassa was in a twofold manner made worthy of the Kingdom of Christ: as a martyr and as the mother of martyrs.” (Prologue)
