2 Corinthians 5.15-21 (Epistle)

15He died for all, that those who live should no longer live to themselves, but to him who for their sakes died and rose again.

16Therefore we know no one according to the flesh from now on. Even though we have known Christ according to the flesh, yet now we know him so no more. 17Therefore if anyone is in Christ, he is a new creation. The old things have passed away. Behold, all things have become new. 18But all things are of God, who reconciled us to himself through Jesus Christ, and gave to us the ministry of reconciliation; 19namely, that God was in Christ reconciling the world to himself, not reckoning to them their trespasses, and having committed to us the word of reconciliation.

20We are therefore ambassadors on behalf of Christ, as though God were entreating by us: we beg you on behalf of Christ, be reconciled to God. 21For him who knew no sin he made to be sin on our behalf, so that in him we might become the righteousness of God.

Mark 1.16-22 (Gospel)

16Passing along by the sea of Galilee, he saw Simon and Andrew, the brother of Simon, casting a net into the sea, for they were fishermen. 17Jesus said to them, “Come after me, and I will make you into fishers for men.”

18Immediately they left their nets, and followed him.

19Going on a little further from there, he saw James the son of Zebedee, and John his brother, who were also in the boat mending the nets. 20Immediately he called them, and they left their father, Zebedee, in the boat with the hired servants, and went after him.

21They went into Capernaum, and immediately on the Sabbath day he entered into the synagogue and taught. 22They were astonished at his teaching, for he taught them as having authority, and not as the scribes.

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)
