Catholic Commentary on Mark 9

"I do believe; help me overcome my unbelief!" (Mark 9:24)

The Transfiguration

Six days after Peter's confession, Jesus takes Peter, James, and John up a high mountain and is transfigured before them. His clothes become dazzling white, whiter than anyone could bleach them. Moses and Elijah appear and speak with him. The voice from the cloud declares: This is my Son, whom I love. Listen to him! The Transfiguration is the Father's confirmation of Peter's confession on the mountain below. For one moment the veil of the Incarnation is drawn back and the disciples see what has been there all along: the glory of the eternal Son.

St. Thomas Aquinas wrote that the Transfiguration was given to strengthen the disciples against the scandal of the Passion. Before they were asked to watch him die, they were allowed to see who he truly was. The Catechism calls it an anticipation of the Resurrection and a foretaste of the glory that awaits those who follow him (CCC 556). The mountain of the Transfiguration stands between Caesarea Philippi and Calvary, giving light to both.

Help My Unbelief

At the foot of the mountain, a man brings his possessed son to the disciples, who cannot drive the demon out. When Jesus arrives and hears the history of the boy's suffering, he commands the demon to come out and never return. But before he does, the father says something that has given hope to believers in every generation: If you can do anything, take pity on us and help us. Jesus gently corrects the conditional: If you can? Everything is possible for one who believes. And the father cries out: I do believe; help me overcome my unbelief! This is one of the most honest prayers in Scripture: faith and doubt held simultaneously, brought to Christ without pretence. Jesus does not wait for the doubt to be resolved. He heals the boy.

Greatness and the Child

The disciples argue about who is the greatest among them. Jesus sits down, calls the Twelve to him, and says: Anyone who wants to be first must be the very last, and the servant of all. Then he takes a little child, stands the child among them, and says: Whoever welcomes one of these little children in my name welcomes me. The Kingdom of God does not operate by the rules of the world. Power flows downward, not upward. The one who serves is the one who leads. The one who welcomes the child, the vulnerable, the unimportant, welcomes Christ himself.

Living the Word

Brothers and sisters, the prayer of the father at the foot of the mountain is one we can all pray without shame: I believe, help my unbelief. We need not pretend to a faith we do not have. We need only bring what we have, however small, to the one who can do everything. He heals in the presence of doubt. He acts in the presence of fear. All he asks is that we come.

Prayer

Lord Jesus, on the mountain you were revealed in glory, and at the foot of the mountain you healed a boy in the presence of his father's struggling faith. We bring you our mixed faith today: real but imperfect, genuine but shaken. Help our unbelief. Transfigure our doubts into trust. Through Christ our Lord. Amen.

The Transfiguration
(Matthew 17:1–13; Luke 9:28–36; 2 Peter 1:16–21)
Then Jesus said to them, “Truly I tell you, there are some standing here who will not taste death before they see the kingdom of God arrive with power.”
 
After six days Jesus took with Him Peter, James, and John, and led them up a high mountain by themselves. There He was transfigured before them. His clothes became radiantly white, brighter than any launderer on earth could bleach them. And Elijah and Moses appeared before them, talking with Jesus.
 
Peter said to Jesus, “Rabbi, it is good for us to be here. Let us put up three shelters * 9:5 Or three tabernacles—one for You, one for Moses, and one for Elijah.” For they were all so terrified that Peter did not know what else to say.
 
Then a cloud appeared and enveloped them, and a voice came from the cloud: “This is My beloved Son. Listen to Him!” Suddenly, when they looked around, they saw no one with them except Jesus.
 
As they were coming down the mountain, Jesus admonished them not to tell anyone what they had seen until the Son of Man had risen from the dead. 10 So they kept this matter to themselves, discussing what it meant to rise from the dead. 11 And they asked Jesus, “Why do the scribes say that Elijah must come first?”
 
12 He replied, “Elijah does indeed come first, and he restores all things. Why then is it written that the Son of Man must suffer many things and be rejected? 13 But I tell you that Elijah has indeed come, and they have done to him whatever they wished, just as it is written about him.”
The Boy with an Evil Spirit
(Matthew 17:14–18; Luke 9:37–42)
 
14 When they returned to the other disciples, they saw a large crowd around them, and scribes arguing with them. 15 As soon as all the people saw Jesus, they were filled with awe and ran to greet Him.
 
16 “What are you disputing with them?” He asked.
 
17 Someone in the crowd replied, “Teacher, I brought You my son, who has a spirit that makes him mute. 18 Whenever it seizes him, it throws him to the ground. He foams at the mouth, gnashes his teeth, and becomes rigid. 9:18 Or and is withering away I asked Your disciples to drive it out, but they were unable.”
 
19 “O unbelieving generation!” Jesus replied. “How long must I remain with you? How long must I put up with you? Bring the boy to Me.”
 
20 So they brought him, and seeing Jesus, the spirit immediately threw the boy into a convulsion. He fell to the ground and rolled around, foaming at the mouth.
 
21 Jesus asked the boy’s father, “How long has this been with him?”
 
“From childhood,” he said. 22 “It often throws him into the fire or into the water, trying to kill him. But if You can do anything, have compassion on us and help us.”
 
23 “If You can?” echoed Jesus. “All things are possible to him who believes!”
 
24 Immediately the boy’s father cried out, 9:24 BYZ and TR cried out with tears “I do believe; help my unbelief!”
 
25 When Jesus saw that a crowd had come running, He rebuked the unclean spirit. “You deaf and mute spirit,” He said, “I command you to come out and never enter him again.”
 
26 After shrieking and convulsing him violently, the spirit came out. The boy became like a corpse, so that many said, “He is dead.” 27 But Jesus took him by the hand and helped him to his feet, and he stood up.
 
28 After Jesus had gone into the house, His disciples asked Him privately, “Why couldn’t we drive it out?”
 
29 Jesus answered, “This kind cannot come out, except by prayer.”§ 9:29 BYZ and TR prayer and fasting
The Second Prediction of the Passion
(Matthew 17:22–23; Luke 9:43–45)
 
30 Going on from there, they passed through Galilee. But Jesus did not want anyone to know, 31 because He was teaching His disciples. He told them, “The Son of Man will be delivered into the hands of men. They will kill Him, and after three days He will rise.” 32 But they did not understand this statement, and they were afraid to ask Him about it.
The Greatest in the Kingdom
(Matthew 18:1–5; Luke 9:46–50)
 
33 Then they came to Capernaum. While Jesus was in the house, He asked them, “What were you discussing on the way?” 34 But they were silent, for on the way they had been arguing about which of them was the greatest.
 
35 Sitting down, Jesus called the Twelve and said, “If anyone wants to be first, he must be the last of all and the servant of all.”
 
36 Then He had a little child stand among them. Taking the child in His arms, He said to them, 37 “Whoever welcomes one of these little children in My name welcomes Me, and whoever welcomes Me welcomes not only Me, but the One who sent Me.”
 
38 John said to Him, “Teacher, we saw someone else driving out demons in Your name, and we tried to stop him, because he does not accompany us.”
 
39 “Do not stop him,” Jesus replied. “For no one who performs a miracle in My name can turn around and speak evil of Me. 40 For whoever is not against us is for us. 41 Indeed, if anyone gives you even a cup of water because you bear the name of Christ, truly I tell you, he will never lose his reward.
Temptations and Trespasses
(Matthew 18:6–9; Luke 17:1–4)
 
42 But if anyone causes one of these little ones who believe in Me to stumble, it would be better for him to have a large millstone hung around his neck and to be thrown into the sea.
 
43 If your hand causes you to sin, cut it off. It is better for you to enter life crippled than to have two hands and go into hell,* 9:43 Greek Gehenna; also in verses 45 and 47 into the unquenchable fire. 9:43 BYZ and TR include 44 where their worm never dies, and the fire is never quenched; see verse 48 and Isaiah 66:24. 45 If your foot causes you to sin, cut it off. It is better for you to enter life lame than to have two feet and be thrown into hell. 9:45 BYZ and TR include 46 where their worm never dies, and the fire is never quenched; see verse 48 and Isaiah 66:24. 47 And if your eye causes you to sin, pluck it out. It is better for you to enter the kingdom of God with one eye than to have two eyes and be thrown into hell, 48 where ‘their worm never dies, and the fire is never quenched.’§ 9:48 Isaiah 66:24
Good Salt
(Matthew 5:13–16; Luke 14:34–35)
 
49 For everyone will be salted with fire.* 9:49 BYZ and TR include and every sacrifice will be salted with salt.
 
50 Salt is good, but if the salt loses its saltiness, with what will you season it? Have salt among yourselves, and be at peace with one another.”
