As he continued his journey to Jerusalem, he traveled through Samaria and Galilee. As he was entering a village, ten lepers met (him). They stood at a distance from him and raised their voice, saying, “Jesus, Master! Have pity on us!” And when he saw them, he said, “Go show yourselves to the priests.” As they were going they were cleansed. And one of them, realizing he had been healed, returned, glorifying God in a loud voice; and he fell at the feet of Jesus and thanked him. He was a Samaritan. Jesus said in reply, “Ten were cleansed, were they not? Where are the other nine? Has none but this foreigner returned to give thanks to God?” Then he said to him, “Stand up and go; your faith has saved you.” (Lk 17:11-19)
This story again gives Jesus’ attitude towards a foreigner: a Samaritan. Samaritans were considered to be lower in the rung of ladder God’s chosen people. So they could not be models for others. In this story a Samaritan puts to shame the chosen people who had been healed but who didn’t say ‘thank you’.
We know that all we have is a gift from God. The land we own, the food we eat, the water we drink, the air we breathe and all the rest of it is a generous gift from God. Man can only be grateful to God for these gifts and nothing else. In fact the Christian tradition says that a grateful person is a redeemed person. Gratitude is a Christian virtue.
Faith here means not just any old belief or any religious attitude to life but the belief that the God of life is at work in and through Jesus. And this fact is realized here and now in this event. God is active in Jesus and the man has to be grateful to God.
