Peter's Denial -- John.18.15 -- Simon Peter followed Jesus, and so did another disciple.

So the other disciple, who was known to the high priest, went out and spoke to the servant girl who kept watch at the door, and brought Peter in.  The servant girl at the door said to Peter, “You also are not one of this man’s disciples, are you?” He said, “I am not.”
 Now the servants and officers had made a charcoal fire, because it was cold, and they were standing and warming themselves. Peter also was with them, standing and warming himself...  Now Simon Peter was standing and warming himself. So they said to him, “You also are not one of his disciples, are you?” He denied it and said, “I am not.”  One of the servants of the high priest, a relative of the man whose ear Peter had cut off, asked, “Did I not see you in the garden with him?”  Peter again denied it, and at once a rooster crowed.

Simon Peter said to them, “I am going fishing.” They said to him, “We will go with you.” They went out and got into the boat, but that night they caught nothing.

Second Conclusion -- John 21:20 -- Peter turned and saw the disciple whom Jesus loved following them, the one who had been reclining at table close to him and had said, “Lord, who is it that is going to betray you?”  When Peter saw him, he said to Jesus, “Lord, what about this man?”
Acts.1.13 And when they had entered, they went up to the upper room, where they were staying, Peter and John and James and Andrew, Philip and Thomas, Bartholomew and Matthew, James the son of Alphaeus and Simon the Zealot and Judas the son of James.

Acts.4.13 Now when they saw the boldness of Peter and John, and perceived that they were uneducated, common men, they were astonished. And they recognized that they had been with Jesus.
Acts.4.19 But Peter and John answered them, “Whether it is right in the sight of God to listen to you rather than to God, you must judge,
Acts.5.3 But Peter said, “Ananias, why has Satan filled your heart to lie to the Holy Spirit and to keep back for yourself part of the proceeds of the land?
Acts.5.8 And Peter said to her, “Tell me whether you sold the land for so much.” And she said, “Yes, for so much.”
Acts.5.9 But Peter said to her, “How is it that you have agreed together to test the Spirit of the Lord? Behold, the feet of those who have buried your husband are at the door, and they will carry you out.”
Acts.5.15 so that they even carried out the sick into the streets and laid them on cots and mats, that as Peter came by at least his shadow might fall on some of them.

Acts.8.20 But Peter said to him, “May your silver perish with you, because you thought you could obtain the gift of God with money!
Acts.9.32 Now as Peter went here and there among them all, he came down also to the saints who lived at Lydda.
Acts.9.34 And Peter said to him, “Aeneas, Jesus Christ heals you; rise and make your bed.” And immediately he rose.
Acts.9.38 Since Lydda was near Joppa, the disciples, hearing that Peter was there, sent two men to him, urging him, “Please come to us without delay.”
Acts.9.39 So Peter rose and went with them. And when he arrived, they took him to the upper room. All the widows stood beside him weeping and showing tunics and other garments that Dorcas made while she was with them.
Acts.9.40 But Peter put them all outside, and knelt down and prayed; and turning to the body he said, “Tabitha, arise.” And she opened her eyes, and when she saw Peter she sat up.

Acts.10.13 And there came a voice to him: “Rise, Peter; kill and eat.”
Acts.10.14 But Peter said, “By no means, Lord; for I have never eaten anything that is common or unclean.”
Acts.10.17 Now while Peter was inwardly perplexed as to what the vision that he had seen might mean, behold, the men who were sent by Cornelius, having made inquiry for Simon’s house, stood at the gate
Acts.10.18 and called out to ask whether Simon who was called Peter was lodging there.
Acts.10.19 And while Peter was pondering the vision, the Spirit said to him, “Behold, three men are looking for you.
Acts.10.21 And Peter went down to the men and said, “I am the one you are looking for. What is the reason for your coming?”
Acts.10.25 When Peter entered, Cornelius met him and fell down at his feet and worshiped him.
Acts.10.26 But Peter lifted him up, saying, “Stand up; I too am a man.”
Acts.10.32 Send therefore to Joppa and ask for Simon who is called Peter. He is lodging in the house of Simon, a tanner, by the sea.’
Acts.10.34 So Peter opened his mouth and said: “Truly I understand that God shows no partiality,
Acts.10.44 While Peter was still saying these things, the Holy Spirit fell on all who heard the word.
Acts.10.45 And the believers from among the circumcised who had come with Peter were amazed, because the gift of the Holy Spirit was poured out even on the Gentiles.
Acts.10.46 For they were hearing them speaking in tongues and extolling God. Then Peter declared,
Acts.11.2 So when Peter went up to Jerusalem, the circumcision party criticized him, saying,
Acts.11.4 But Peter began and explained it to them in order:
Acts.11.7 And I heard a voice saying to me, ‘Rise, Peter; kill and eat.’
Acts.11.13 And he told us how he had seen the angel stand in his house and say, ‘Send to Joppa and bring Simon who is called Peter;
Acts.12.3 and when he saw that it pleased the Jews, he proceeded to arrest Peter also. This was during the days of Unleavened Bread.
Acts.12.5 So Peter was kept in prison, but earnest prayer for him was made to God by the church.
Acts.12.6 Now when Herod was about to bring him out, on that very night, Peter was sleeping between two soldiers, bound with two chains, and sentries before the door were guarding the prison.
Acts.12.7 And behold, an angel of the Lord stood next to him, and a light shone in the cell. He struck Peter on the side and woke him, saying, “Get up quickly.” And the chains fell off his hands.
Acts.12.11 When Peter came to himself, he said, “Now I am sure that the Lord has sent his angel and rescued me from the hand of Herod and from all that the Jewish people were expecting.”
Acts.12.14 Recognizing Peter’s voice, in her joy she did not open the gate but ran in and reported that Peter was standing at the gate.
Acts.12.16 But Peter continued knocking, and when they opened, they saw him and were amazed.
Acts.12.18 Now when day came, there was no little disturbance among the soldiers over what had become of Peter.
Acts.15.7 And after there had been much debate, Peter stood up and said to them, “Brothers, you know that in the early days God made a choice among you, that by my mouth the Gentiles should hear the word of the gospel and believe.
1Cor.1.12 What I mean is that each one of you says, “I follow Paul,” or “I follow Apollos,” or “I follow Cephas,” or “I follow Christ.”
1Cor.3.22 whether Paul or Apollos or Cephas or the world or life or death or the present or the future—all are yours,
1Cor.9.5 Do we not have the right to take along a believing wife, as do the other apostles and the brothers of the Lord and Cephas?
1Cor.15.5 and that he appeared to Cephas, then to the twelve.
Gal.1.18 Then after three years I went up to Jerusalem to visit Cephas and remained with him fifteen days.
Gal.2.7 On the contrary, when they saw that I had been entrusted with the gospel to the uncircumcised, just as Peter had been entrusted with the gospel to the circumcised
Gal.2.8 (for he who worked through Peter for his apostolic ministry to the circumcised worked also through me for mine to the Gentiles),
Gal.2.9 and when James and Cephas and John, who seemed to be pillars, perceived the grace that was given to me, they gave the right hand of fellowship to Barnabas and me, that we should go to the Gentiles and they to the circumcised.
Gal.2.11 But when Cephas came to Antioch, I opposed him to his face, because he stood condemned.
Gal.2.14 But when I saw that their conduct was not in step with the truth of the gospel, I said to Cephas before them all, “If you, though a Jew, live like a Gentile and not like a Jew, how can you force the Gentiles to live like Jews?”
1Pet.1.1 Peter, an apostle of Jesus Christ, To those who are elect exiles of the dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia,
2Pet.1.1 Simon Peter, a servant and apostle of Jesus Christ, To those who have obtained a faith of equal standing with ours by the righteousness of our God and Savior Jesus Christ:
Eusebius, Historia ecclesiastica
< Peter imprisoned under Herod Agrippa I >
II 9,4 -- And then, as the divine Scripture says, <Acts 12:3ff> Herod (Agrippa), upon the death of James, seeing that the deed pleased the Jews, attacked Peter also and committed him to prison, and would have slain him if he had not, by the divine appearance of an angel who came to him by night, been wonderfully released from his bonds, and thus liberated for the service of the Gospel. Such was the providence of God in respect to Peter.
< Simon Magus and Peter >
II -- [14,4] The evil deeds done by Simon Magus were first detected by the apostle Peter in Judea... [14,6] (Finally) during the reign of Claudius, the all-good and gracious Providence, which watches over all things, led Peter, that strongest and greatest of the apostles, and the one who on account of his virtue was the speaker for all the others, to Rome against this great corrupter of life. He like a noble commander of God, clad in divine armor, carried the costly merchandise of the light of the understanding from the East to those who dwelt in the West, proclaiming the light itself, and the word which brings salvation to souls, and preaching the kingdom of heaven. [15,1] And thus when the divine word had made its home among them, the power of Simon was quenched and immediately destroyed, together with the man himself...
< The Gospel of Mark >
II -- [15,1] ... So greatly did the splendor of piety illumine the minds of Peter's hearers that they were not satisfied with hearing once only, and were not content with the unwritten teaching of the divine Gospel, but with all sorts of entreaties they besought Mark, a follower of Peter, and the one whose Gospel is extant, that he would leave them a written monument of the doctrine which had been orally communicated to them. Nor did they cease until they had prevailed with the man, and had thus become the occasion of the written Gospel which bears the name of Mark. [15,2] And they say that Peter — when he had learned, through a revelation of the Spirit, of that which had been done — was pleased with the zeal of the men, and that the work obtained the sanction of his authority for the purpose of being used in the churches. Clement in the eighth book of his Hypotyposes gives this account, and with him agrees the bishop of Hierapolis named Papias. And Peter makes mention of Mark in his first epistle which they say that he wrote in Rome itself, as is indicated by him, when he calls the city, by a figure, Babylon, as he does in the following words: "The church that is at Babylon, elected together with you, salutes you; and so does Marcus my son."
< Peter and Philo of Alexandra >
II 17,1 -- It is also said that Philo in the reign of Claudius became acquainted at Rome with Peter, who was then preaching there. Nor is this indeed improbable, for the work of which we have spoken, and which was composed by him some years later, clearly contains those rules of the Church which are even to this day observed among us.
< Preaching of Peter >
III 1,2 -- Peter appears to have preached in Pontus, Galatia, Bithynia, Cappadocia, and Asia to the Jews of the dispersion. And at last, he came to Rome...
III 4,2 -- And in how many provinces Peter preached Christ and taught the doctrine of the new covenant to those of the circumcision is clear from his own words in his epistle already mentioned as undisputed, in which he writes to the Hebrews of the dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia. <1 Peter 1:1>
Death of Peter
II 25,5 It is recorded that Paul was beheaded in Rome itself, and that Peter likewise was crucified under Nero. This account of Peter and Paul is substantiated by the fact that their names are preserved in the cemeteries of that place even to the present day. [25,6] It is confirmed likewise by Caius, a member of the Church, who arose under Zephyrinus, bishop of Rome. He, in a published disputation with Proclus, the leader of the Phrygian heresy, speaks as follows concerning the places where the sacred corpses of the aforesaid apostles are laid: [25,7] "But I can show the trophies of the apostles. For if you will go to the Vatican or to the Ostian way, you will find the trophies of those who laid the foundations of this church." [25,8] And that they both suffered martyrdom at the same time is stated by Dionysius, bishop of Corinth, in his epistle to the Romans, in the following words: "You have thus by such an admonition bound together the planting of Peter and of Paul at Rome and Corinth. For both of them planted and likewise taught us in our Corinth. And they taught together in like manner in Italy, and suffered martyrdom at the same time." I have quoted these things in order that the truth of the history might be still more confirmed.
III 1,2 -- (Peter) was crucified head-downwards; for he had requested that he might suffer in this way.
III 3,1 -- One epistle of Peter, that called the first, is acknowledged as genuine. And this the ancient elders used freely in their own writings as an undisputed work. But we have learned that his extant second Epistle does not belong to the canon; yet, as it has appeared profitable to many, it has been used with the other Scriptures. [3,2] The so-called Acts of Peter, however, and the Gospel which bears his name, and the Preaching and the Apocalypse, as they are called, we know have not been universally accepted, because no ecclesiastical writer, ancient or modern, has made use of testimonies drawn from them. [3,3] But in the course of my history I shall be careful to show, in addition to the official succession, what ecclesiastical writers have from time to time made use of any of the disputed works, and what they have said in regard to the canonical and accepted writings, as well as in regard to those which are not of this class. [3,4] Such are the writings that bear the name of Peter, only one of which I know to be genuine and acknowledged by the ancient elders.
< Peter's apostolic succession >
III 2,1 -- After the martyrdom of Paul and of Peter, Linus was the first to obtain the episcopate of the church at Rome. Paul mentions him, when writing to Timothy from Rome, in the salutation at the end of the epistle.
III -- [4,3] The number and the names of those among them that became true and zealous followers of the apostles, and were judged worthy to tend the churches founded by them, it is not easy to tell, except those mentioned in the writings of Paul... [4,9] Linus, whom (Paul) mentions in the Second Epistle to Timothy <2 Timothy 4:21> as his companion at Rome, was Peter's successor in the episcopate of the church there, as has already been shown.
