+ Mk 9: 14-29
When they came to the disciples, they saw a large crowd around them and scribes arguing with them.
Immediately on seeing him, the whole crowd was utterly amazed. They ran up to him and greeted him.
He asked them, “What are you arguing about with them?”
Someone from the crowd answered him, “Teacher, I have brought to you my son possessed by a mute spirit.
Wherever it seizes him, it throws him down; he foams at the mouth, grinds his teeth, and becomes rigid. I asked your disciples to drive it out, but they were unable to do so.”
He said to them in reply, “O faithless generation, how long will I be with you? How long will I endure you? Bring him to me.”
They brought the boy to him. And when he saw him, the spirit immediately threw the boy into convulsions. As he fell to the ground, he began to roll around and foam at the mouth.
Then he questioned his father, “How long has this been happening to him?” He replied, “Since childhood.
It has often thrown him into fire and into water to kill him. But if you can do anything, have compassion on us and help us.”
Jesus said to him, ” ‘If you can!’ Everything is possible to one who has faith.”
Then the boy’s father cried out, “I do believe, help my unbelief!”
Jesus, on seeing a crowd rapidly gathering, rebuked the unclean spirit and said to it, “Mute and deaf spirit, I command you: come out of him and never enter him again!”
Shouting and throwing the boy into convulsions, it came out. He became like a corpse, which caused many to say, “He is dead!”
But Jesus took him by the hand, raised him, and he stood up.
When he entered the house, his disciples asked him in private, “Why could we not drive it out?”
He said to them, “This kind can only come out through prayer.”
The New American Bible
The Catechism of the Catholic Church
2610 Just as Jesus prays to the Father and gives thanks before receiving his gifts, so he teaches us filial boldness: “Whatever you ask in prayer, believe that you receive it, and you will.” Such is the power of prayer and of faith that does not doubt: “all things are possible to him who believes.” Jesus is as saddened by the “lack of faith” of his own neighbors and the “little faith” of his own disciples as he is struck with admiration at the great faith of the Roman centurion and the Canaanite woman.
162 Faith is an entirely free gift that God makes to man. We can lose this priceless gift, as St. Paul indicated to St. Timothy: “Wage the good warfare, holding faith and a good conscience. By rejecting conscience, certain persons have made shipwreck of their faith.” To live, grow and persevere in the faith until the end we must nourish it with the word of God; we must beg the Lord to increase our faith; it must be “working through charity,” abounding in hope, and rooted in the faith of the Church.
1504 Often Jesus asks the sick to believe. He makes use of signs to heal: spittle and the laying on of hands, mud and washing. The sick try to touch him, “for power came forth from him and healed them all.” And so in the sacraments Christ continues to “touch” us in order to heal us.
