NEW TESTAMENT: 2 Timothy 2: 8 - 15 (RCL)
2 Timothy 2: 8 - 13 (Roman Catholic)

2Tim 2:8 (NRSV) 8 Remember Jesus Christ, raised from the dead, a descendant of David--that is my gospel, 9 for which I suffer hardship, even to the point of being chained like a criminal. But the word of God is not chained. 10 Therefore I endure everything for the sake of the elect, so that they may also obtain the salvation that is in Christ Jesus, with eternal glory. 11 The saying is sure:
If we have died with him, we will also live with him;
12 if we endure, we will also reign with him;
if we deny him, he will also deny us;
13 if we are faithless, he remains faithful--
for he cannot deny himself.
14 Remind them of this, and warn them before God that they are to avoid wrangling over words, which does no good but only ruins those who are listening. 15 Do your best to present yourself to God as one approved by him, a worker who has no need to be ashamed, rightly explaining the word of truth.

Timothy, we read last week, lacks the courage to hand on the good news, perhaps because he leads a Christian community subject to ostracism or persecution. He is even ashamed of being Christian. The author, writing in Paul’s name, wishes that he rekindle his faith and follow Paul’s example. Using three illustrations (“soldier”, v. 3; “athlete”, v. 5; “farmer”, v. 6), Paul has told Timothy that being a Christian requires single-mindedness, self-denial and intense effort. Reflection will lead Timothy to God giving him complete understanding.
Now he is advised to recall what Paul taught: Christ, restored to God, is the kingly Messiah (“descendant of David”, v. 8) long expected. Paul continues to preach this despite “hardship” (v. 9) and imprisonment. Even so, the good news is available to all and continues to spread (“not chained”). Paul is the great example of enduring for those who are already Christian and for those who will come to faith (“the elect”, v. 10), enabling them to enjoy Christ’s promise of eternal life.

2:9: “the word of God is not chained”: In Philippians 1:12-14, Paul says that his imprisonment has made many Christians “confident in the Lord” so that they now “dare to speak the word with greater boldness and without fear”. [NOAB]

GOSPEL: Luke 17: 11 - 19 (all)

Luke 17:11 (NRSV) On the way to Jerusalem Jesus was going through the region between Samaria and Galilee. 12 As he entered a village, ten lepers approached him. Keeping their distance, 13 they called out, saying, "Jesus, Master, have mercy on us!" 14 When he saw them, he said to them, "Go and show yourselves to the priests." And as they went, they were made clean. 15 Then one of them, when he saw that he was healed, turned back, praising God with a loud voice. 16 He prostrated himself at Jesus' feet and thanked him. And he was a Samaritan. 17 Then Jesus asked, "Were not ten made clean? But the other nine, where are they? 18 Was none of them found to return and give praise to God except this foreigner?" 19 Then he said to him, "Get up and go on your way; your faith has made you well."

esus is on the final leg of his journey from Galilee to Jerusalem. He told his disciples how important genuine faith is. Lepers were outcasts from society; people considered them ritually unclean, believed the disease to be infectious by touch, and thought they were possessed by evil spirits. All ten acknowledge Jesus as who he is, “Master” (v. 13): they have faith. To be restored to society, a leper needed certification from “the priests” (v. 14) that he was free of the disease.
While all ten acknowledge Jesus as God, only one, a “Samaritan” (v. 16), a “foreigner” (v. 18), gives thanks to him (v. 16); he worships God differently. All ten are healed of leprosy but only one is wholly “made ... well” (v. 19) – for the Greek word bears with it the idea of rescue from impending destruction or from superior powers. Much earlier, Jesus has infuriated synagogue worshippers by recalling the story of Naaman, the foreigner healed of leprosy by Elisha. Then no Israelites were healed of the disease, only an alien. Now one whom Jews despised is saved. See 7:27 for cleansing of lepers being a sign of the coming of the Kingdom.
Verse 14: “‘Go and show yourselves to the priests”: Leviticus 13:2-3 commands: “When a person has on the skin of his body a swelling or an eruption or a spot, and it turns into a leprous disease on the skin of his body, he shall be brought to Aaron the priest or to one of his sons the priests. The priest shall examine the disease on the skin of his body, and if the hair in the diseased area has turned white and the disease appears to be deeper than the skin of his body, it is a leprous disease; after the priest has examined him he shall pronounce him ceremonially unclean”. See also Leviticus 13:49 and 14:2-32.
