(16) And he was a Samaritan.—As in the parable of the Good Samaritan, St. Luke’s purpose in the selection of the incident falls in with what may be called the Catholicity of his Gospel, the breaking down of every middle wall of partition that divided the Jew from the other nations of the world. As the narrative is peculiar to his record, we may reasonably believe that it was one of the facts with which he became acquainted in the course of his personal inquiries in Galilee and Samaria. It is significant, in this case, that the barrier had been already broken down for a time by the common pressure of calamity, but no enduring sense of fellowship had as yet taken its place. The nine would seem to have separated themselves from the Samaritan as soon as they were cleansed. Men want more than the “misery” which our common proverb associates with “strange” companions, before they learn the lesson of brotherhood in its fulness.

17:11-19 A sense of our spiritual leprosy should make us very humble whenever we draw near to Christ. It is enough to refer ourselves to the compassions of Christ, for they fail not. We may look for God to meet us with mercy, when we are found in the way of obedience. Only one of those who were healed returned to give thanks. It becomes us, like him, to be very humble in thanksgivings, as well as in prayers. Christ noticed the one who thus distinguished himself, he was a Samaritan. The others only got the outward cure, he alone got the spiritual blessing.One of them ... - This man, sensible of the power of God and grateful for his mercies, returned to express his gratitude to God for his goodness. Instead of obeying "at once" the "letter" of the command, he "first" expressed his thanks to God and to his Great Benefactor. There is no evidence, however, that he did not, "after" he had given thanks to God, and had poured out his joy at the feet of Jesus, go to the priest as he was directed; indeed, he could not have been restored to society without doing it; but he "first" poured out his thanks to God, and gave him praise for his wonderful recovery. The first duty of sinners, after they have been forgiven and have the hope of eternal life, is to prostrate themselves at the feet of their Great Benefactor, and to consecrate themselves to his service. "Then" let them go and show to others the evidence that they are cleansed. Let them go and mingle, like a restored leper, with their families and friends, and show by the purity and holiness of their lives how great is the mercy that has cleansed them.

He was a Samaritan - See the notes at Matthew 10:5. This rendered his conduct more remarkable and striking in the sight of the Jews. "They" considered the Samaritans as especially wicked, and "themselves" as especially holy. This example showed them, like the parable of the good Samaritan, that in this they were mistaken: and one design of this seems to have been to break down the "opposition" between the Jews and Samaritans, and to bring the former to more charitable judgments respecting the latter.

14. show yourselves—as cleansed persons. (See on [1686]Mt 8:4.) Thus too would the Samaritan be taught that "salvation is of the Jews" (Joh 4:22).

as they went, were cleansed—In how many different ways were our Lord's cures wrought, and this different from all the rest.

See Poole on "Luke 17:15"

And he fell down on his face at his feet,.... For being cleansed, he might draw nigh unto Jesus; and which he did, with the most profound respect unto him, and reverence of him; and having a deep sense of the favour he had received from him, prostrated himself in this manner before him:

giving him thanks; who had shown compassion to him, had exerted his power on him, and had favoured him with such a singular mercy, as restoring him to health:

and he was a Samaritan; this is particularly remarked by the evangelist, because the Samaritans were reckoned by the Jews, to be ignorant and irreligious persons, and no better than Heathens; and yet this man behaved as a religious good man, who had a sense of his mercy, knew his duty, and his obligations, and performed them; when the other nine, who very likely were all Jews, acted a very stupid and ungrateful part.

And fell down on his face at his feet, giving him thanks: and he was a Samaritan.
