Luke 17:12-19
[The Ten Cleansed Lepers]
At that time, as Jesus entered a village, he was met by ten lepers, who stood at a distance and lifted up their voices and said: “Jesus, Master, have mercy on us. “When he saw them he said to them, “Go and show yourselves to the priests.” And as they went they were cleansed. Then one of them, when he saw that he was healed, turned back, praising God with a loud voice; and he fell on his face at Jesus’s feet, giving him thanks. Now he was a Samaritan. Then said Jesus: “Were not ten cleansed? Where are the nine? Was no one found to return and give praise to God except this foreigner?” And he said to him: “Rise and go your way; your faith has made you well.”
"[...] In the ancient world, leprosy brought great physical suffering, banishment, and isolation from society. Lepers were removed from any contact with family or friends. In the Jewish context, they were not permitted to enter the Temple nor participate in Israel’s religious or liturgical life. The lepers were at the outskirts of the village, but when they heard that Christ had come, they entered the town and, standing at a distance, addressed Him as “Master” and asked for His mercy.
The lepers come to Jesus with a cry from their hearts as they “lifted up their voices.” It was not a quiet, tentative request but an urgent cry from those dying and suffering on society’s fringes, alone and miserable. When Jesus saw them, He immediately told them: “Go and show yourselves to the priests.”
This might have been a very puzzling command to the lepers. In the Old Testament, the Mosaic Law required that people with leprosy be isolated. Still, if they were ever to be cured by a miracle, they were to go back to the priests for restoration (see, for example, Leviticus 14:3-31).
No doubt, the lepers knew of the Law that regulated their condition, but now Jesus sends them to the priests without curing them first – at least as far as they could understand. Notice that Jesus did not touch them, as He often did in other healings. This is because the Lord heals us in His way and in His own time.
Here is where faith and obedience come into play. The lepers obey the word of Jesus without questioning why they were asked to show themselves to the priests while they were still apparently diseased. They did not question the Lord nor oppose His command but went as He told them. We read that as they went, they were cleansed.
Notice that their healing came about while they were, first, exercising their faith in Him and second, obeying Him without question. They believed and obeyed Him as they departed and made their way to Jerusalem, where the priests resided. This was a display of faith and works. They had faith in Christ and His words and showed their works through obedience.
The virtue of obedience is essential in our relationship with God and is often mentioned in the writings of the Church Fathers. Saint John of the Ladder says, “Obedience is ... a voluntary death ... the tomb of the will and the resurrection of humility.” Voluntary obedience, in other words, is the means through which we set aside our personal cares and self-interest and arise as true sons and daughters of God.
Ten lepers were healed, but only one, a Samaritan, thanked the Lord. He turned back, praising God with a loud voice, and fell to his knees at Jesus’ feet, giving Him thanks. To the Samaritan, Jesus was no longer just a “Master,” but his “Lord” – not simply the One Who commands, but his Benefactor.
[...] The Samaritan’s thanksgiving was an act of love – and Christ honors the gratitude of the Samaritan while remarking on the ungratefulness of the others. The Lord does this to show us that faith alone will not save us because true faith includes obedience and thankfulness. That is why it is essential to show our gratitude to God. Love for Christ leads us to be grateful and obey His commandments (John 14:15).
The Church teaches us to be thankful even during difficult times and to say, “Glory to God”, no matter what might happen. As Saint Peter of Damascus says, “Be mindful of God at all times, in all places, and in every circumstance. For no matter what you do, you should keep in mind the Creator of all things . . . everything you do becomes for you an occasion for glorifying God.”
