1After six days, Jesus took with him Peter, James, and John his brother, and brought them up into a high mountain by themselves. 2He was changed before them. His face shone like the sun, and his garments became as white as the light. 3Behold, Moses and Elijah appeared to them talking with him.
4Peter answered and said to Jesus, “Lord, it is good for us to be here. If you want, let’s make three tents here: one for you, one for Moses, and one for Elijah.”
5While he was still speaking, behold, a bright cloud overshadowed them. Behold, a voice came out of the cloud, saying, “This is my beloved Son, in whom I am well pleased. Listen to him.”
6When the disciples heard it, they fell on their faces, and were very afraid. 7Jesus came and touched them and said, “Get up, and don’t be afraid.” 8Lifting up their eyes, they saw no one, except Jesus alone.
9As they were coming down from the mountain, Jesus commanded them, saying, “Don’t tell anyone what you saw, until the Son of Man has risen from the dead.”
10His disciples asked him, saying, “Then why do the scribes say that Elijah must come first?”
11Jesus answered them, “Elijah indeed comes first, and will restore all things; 12but I tell you that Elijah has come already, and they didn’t recognize him, but did to him whatever they wanted to. Even so the Son of Man will also suffer by them.” 13Then the disciples understood that he spoke to them of John the Baptizer.
14When they came to the multitude, a man came to him, kneeling down to him and saying, 15“Lord, have mercy on my son, for he is epileptic and suffers grievously; for he often falls into the fire, and often into the water. 16So I brought him to your disciples, and they could not cure him.”
17Jesus answered, “Faithless and perverse generation! How long will I be with you? How long will I bear with you? Bring him here to me.” 18Jesus rebuked the demon, and it went out of him, and the boy was cured from that hour.
19Then the disciples came to Jesus privately, and said, “Why weren’t we able to cast it out?”
20He said to them, “Because of your unbelief. For most certainly I tell you, if you have faith as a grain of mustard seed, you will tell this mountain, ‘Move from here to there,’ and it will move; and nothing will be impossible for you. 21But this kind doesn’t go out except by prayer and fasting.”
22While they were staying in Galilee, Jesus said to them, “The Son of Man is about to be delivered up into the hands of men, 23and they will kill him, and the third day he will be raised up.”
They were exceedingly sorry.
24When they had come to Capernaum, those who collected the didrachma coins came to Peter, and said, “Doesn’t your teacher pay the didrachma?” 25He said, “Yes.”
When he came into the house, Jesus anticipated him, saying, “What do you think, Simon? From whom do the kings of the earth receive toll or tribute? From their children, or from strangers?”
26Peter said to him, “From strangers.”
Jesus said to him, “Therefore the children are exempt. 27But, lest we cause them to stumble, go to the sea, cast a hook, and take up the first fish that comes up. When you have opened its mouth, you will find a stater coin. Take that, and give it to them for me and you.”
Peter, also known as Simon or Cephas, was a married fisherman (1 Cor 9:5) living in Capernaum (Mark 1:30) when Jesus called him to be a “fisher of men.” Peter became the leader of the apostles and disciples; the Roman Catholic Church believes that he was the first pope of Rome, but this is neither attested in the New Testament nor in the earliest church history. His name is always mentioned first in the lists of the Twelve, and he accompanied Jesus at several important moments in Jesus ministry- the transfiguration (Mark 9:22) and the Garden of Gethsemane (Mark 14:32). Peter was also the first to confess Jesus as “the Christ, the Son of the living God” (Matt 16:16) and was spokesman for the Apostles at Pentecost (Acts 2:14-40). Impetuous and spontaneous, Peter often spoke or acted before thinking, like when he offered to build a tabernacle to Moses and Elijah (Matt 17:1-5), when he cut off Malchus’ ear in the Garden (Luke 22:50) or denying Jesus several times after promising he would never do so (Luke 22:54-62). Church tradition says Peter was martyred on a cross, but he requested to be crucified upside down, saying that he was not worthy to die as his Lord had died.
