At the beginning of Peter's apostleship, Peter said to Jesus that he was just a simple man and requested that Jesus look away from him, that he might have peace. Later, Peter was to proclaim Jesus to be the Son of God and realized that Jesus' words were the gift of life. There was no other place Peter wished to be.
This is a Psalm of King David, but perhaps Peter would have thought similarly during the arrest and trial of Jesus.
Psalm 39
1 I said, "I will watch my ways
and keep my tongue from sin;
I will put a muzzle on my mouth
as long as the wicked are in my presence."
2 But when I was silent and still,
not even saying anything good,
my anguish increased.
3 My heart grew hot within me,
and as I meditated, the fire burned;
then I spoke with my tongue:
4 "Show me, O LORD, my life's end
and the number of my days;
let me know how fleeting is my life.
5 You have made my days a mere handbreadth;
the span of my years is as nothing before you.
Each man's life is but a breath.
Selah
6 Man is a mere phantom as he goes to and fro:
He bustles about, but only in vain;
he heaps up wealth, not knowing who will get it.
7 "But now, Lord, what do I look for?
My hope is in you.
8 Save me from all my transgressions;
do not make me the scorn of fools.
9 I was silent; I would not open my mouth,
for you are the one who has done this.
10 Remove your scourge from me;
I am overcome by the blow of your hand.
11 You rebuke and discipline men for their sin;
you consume their wealth like a moth—
each man is but a breath.
Selah
12 "Hear my prayer, O LORD,
listen to my cry for help;
be not deaf to my weeping.
For I dwell with you as an alien,
a stranger, as all my fathers were.
13 Look away from me, that I may rejoice again
before I depart and am not more."
Luke 5: 6 When they had done so, they caught such a large number of fish that their nets began to break. 7 So they signaled their partners in the other boat to come and help them, and they came and filled both boats so full that they began to sink.
8 When Simon Peter saw this, he fell at Jesus' knees and said, "Go away from me, Lord; I am a sinful man!"
Matthew 15: 25 During the fourth watch of the night Jesus went out to them, walking on the lake. 26 When the disciples saw him walking on the lake, they were terrified. "It's a ghost," they said, and cried out in fear.
27 But Jesus immediately said to them: "Take courage! It is I. Don't be afraid." 28"Lord, if it's you," Peter replied, "tell me to come to you on the water." 29"Come," he said.
Then Peter got down out of the boat, walked on the water and came toward Jesus. 30 But when he saw the wind, he was afraid and, beginning to sink, cried out, "Lord, save me!" 31 Immediately Jesus reached out his hand and caught him. "You of little faith," he said, "why did you doubt?"
Mark 10:32
32They were on their way up to Jerusalem, with Jesus leading the way, and the disciples were astonished, while those who followed were afraid. Again he took the twelve aside and told them what was going to happen to him.
Mark 4: 37 A furious squall came up, and the waves broke over the boat, so that it was nearly swamped. 38 Jesus was in the stern, sleeping on a cushion. The disciples woke him and said to him, "Teacher, don't you care if we drown?"
39 He got up, rebuked the wind and said to the waves, "Quiet! Be still!" Then the wind died down and it was completely calm.
40 He said to his disciples, "Why are you so afraid? Do you still have no faith?"
41 They were terrified and asked each other, "Who is this? Even the wind and the waves obey him!"
John 21: 15 When they had finished eating, Jesus said to Simon Peter, "Simon son of John, do you truly love me more than these?" "Yes, Lord," he said, "you know that I love you." Jesus said, "Feed my lambs."
16Again Jesus said, "Simon son of John, do you truly love me?" He answered, "Yes, Lord, you know that I love you." Jesus said, "Take care of my sheep."
17 The third time he said to him, "Simon son of John, do you love me?" Peter was hurt because Jesus asked him the third time, "Do you love me?" He said, "Lord, you know all things; you know that I love you."
Jesus said, "Feed my sheep. 18 I tell you the truth, when you were younger you dressed yourself and went where you wanted; but when you are old you will stretch out your hands, and someone else will dress you and lead you where you do not want to go." 19Jesus said this to indicate the kind of death by which Peter would glorify God. Then he said to him, "Follow me!"
Matthew 16:18
And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it.
In 1939, Pius XII began an underground excavation to organize the space into a proper underground chapel for the bones of the popes. By 1941, it had become clear that a major area of archaeological importance had been discovered. A whole street of tombs came to light, some 300 feet long, with tombs on both sides.
After more that 25 years of research, Paul VI shared his knowledge and his joy with the world on 26th June 1968: the bones of St. Peter, the rock, had been found. On the evening of the 27th, at a ceremony before the aedicula attended by the Pope, Professors Guarducci and Correnti, the bones were restored to the loculus in the Graffiti Wall. A short prayer was said and the shrine to Peter was closed off from the street of tombs by a heavy wrought iron gate.
The Graffiti Wall was very similar to the wall found in Peter's house in Capernaum ~ it declared: "Petr[os] en[i]", "Peter is here within". Alpha and omega combinations were present, as references to Christ, but they were also found in reverse order, signifying Christ's role as the gateway to eternal life. Alpha and omega might also be separated from each other and connected by a thin line. Other letters signified other mysteries: tau indicated the cross, epsilon stood for Eden and nu for "nika", victory. But most important of all, curious combinations of rho and pi were references to the apostle Peter. Not only did Guarducci uncover the spiritual richness and hunger of those who visited the Graffiti Wall, she revealed that there were no fewer than twenty references to Peter on it.
Most important of all, the remains of an elderly man, aged between 60 and 70 of robust stature with the feet missing. Peter was crucified upside down and removed from the cross without his feet. The bones also had traces of earth clinging to them, showing that they had once been interred in the ground. When Correnti carried out tests on the soil beneath the aedicula it provided a perfect match. And finally, mingling with the bones from the loculus were the slightest traces of a distinctive garment: purple in colour and containing fine strands of gold thread. Under Constantine, early in the fourth century, the bones were taken out, wrapped in an expensive purple and gold cloth as a sign of their revered status.
Sceptics do not agree that these are the bones of Peter, but faith is of substance unseen.
