Peter identified Jesus as the Christ and the Son of the living God, yet he soon rebuked Him for saying He would suffer and die. His answer was true, but he still needed Jesus to explain what it meant. I need to hear that correction as well, because using the right titles for Jesus does not give me the right to decide what kind of Savior He must be.
The Question and Peter’s Confession
Matthew, Mark, and Luke preserve this conversation from Jesus’ ministry. The disciples had seen Him heal the sick, cast out demons, command the forces of nature, and raise the dead. Conflict with the religious leaders had been growing, and He had warned His disciples about corrupt teaching. In the region of Caesarea Philippi, He asked them to identify Him:
He said to them, “But who do you say that I am?” Simon Peter answered and said, “You are the Christ, the Son of the living God.” Jesus answered and said to him, “Blessed are you, Simon Bar-Jonah, for flesh and blood has not revealed this to you, but My Father who is in heaven.
Jesus first asked what other people were saying about Him. Some identified Him as John the Baptist, while others named Elijah, Jeremiah, or another prophet (Matthew 16:13-14). Herod had feared that John had risen from the dead, and Malachi’s prophecy gave people reason to expect Elijah. Naming Jeremiah placed Jesus among Israel’s great prophetic voices. These answers treated Him as someone significant, yet none acknowledged who He really was.
He then asked, “But who do you say that I am?” Reporting other people’s opinions had not required the disciples to accept one. Now they had to answer personally. Peter spoke for them: “You are the Christ, the Son of the living God.” Mark records the shorter confession (Mark 8:29), “You are the Christ,” while Luke gives “The Christ of God.” Each account identifies the same Person as God’s promised Christ.
Jesus had called Himself the Son of Man. That title speaks of His real humanity and recalls Daniel 7, where one like a son of man receives everlasting dominion. The man standing before the disciples was God’s promised ruler. Calling Him merely another prophet could not account for His identity or the authority He exercised.
Jesus called Peter blessed and addressed him as Simon Bar-Jonah, meaning Simon son of Jonah. The contrast between “Flesh and blood” and the Father identifies the source of Peter’s understanding. He had heard Jesus teach and had witnessed His works, but the answer was not an achievement of unaided human judgment. The Father had made known to him the identity of the One He had promised and sent.
That revelation did not make the evidence unnecessary. Scripture records the Son’s words and works, and the Holy Spirit bears truthful witness to Him. Faith receives the testimony God has given. Peter could not take credit for being more perceptive than the crowd, and I cannot treat knowing Christ as proof of my own cleverness.
We can speak respectfully about Jesus and still deny Him. Calling Him a wise teacher, reformer, revolutionary, or example of love cannot replace receiving Him as the Christ and the Son of God. Nor can popularity, sincerity, or an inherited religious opinion settle the question. His identity is established by God’s revelation, and the consequences of refusing Him extend beyond this life.
The Christ and the Son of the Living God
The Greek title Christos corresponds to the Hebrew Messiah, meaning Anointed One. “Christ” is a title, not Jesus’ family name. It identifies Him as God’s promised King, who is also our Priest and Deliverer. Psalm 2 brings His kingship and sonship together:
“Yet I have set My King On My holy hill of Zion.” “I will declare the decree: The LORD has said to Me, ‘You are My Son, Today I have begotten You. Ask of Me, and I will give You The nations for Your inheritance, And the ends of the earth for Your possession. You shall break them with a rod of iron; You shall dash them to pieces like a potter’s vessel.'”
The nations oppose the LORD and His Anointed, but they cannot prevent God from establishing His King in Zion (Psalm 2:1-6). God addresses the King as Son and gives Him the nations as His inheritance. The words “Today I have begotten You” announce the Son in His royal office; they do not describe His creation or the beginning of His existence. Earthly rulers are called to submit to Him, warned of judgment, and offered blessing through trusting Him (Psalm 2:10-12).
The promise of that enduring kingship also runs through God’s covenant with David. David’s descendants would reign after him, but the promise reaches beyond any one of their temporary reigns:
“When your days are fulfilled and you rest with your fathers, I will set up your seed after you, who will come from your body, and I will establish his kingdom. He shall build a house for My name, and I will establish the throne of his kingdom forever. I will be his Father, and he shall be My son. If he commits iniquity, I will chasten him with the rod of men and with the blows of the sons of men. But My mercy shall not depart from him, as I took it from Saul, whom I removed from before you. And your house and your kingdom shall be established forever before you. Your throne shall be established forever.”‘”
Solomon built the temple, and the fallible kings in David’s line could commit iniquity and receive chastening. The clause about sin and its correction applies to those descendants. It cannot describe Jesus as though He had sinned or needed punishment for wrongdoing. The everlasting throne finds its final fulfillment in the sinless Son of David.
By taking on true humanity, Jesus entered David’s line. He did not begin to exist at His birth: He is the eternal Son who was with the Father before creation and through whom all things were made. He was never a created man who later became divine, and becoming man neither ended nor diminished His deity.
The “living God” is the source of life, in contrast to powerless idols. His Son shares His divine nature while remaining personally distinct from the Father and the Holy Spirit. We confess one God in three co-equal, co-eternal Persons. The title “Son of God” speaks of His unique personal relationship with the Father, not biological offspring produced by a physical union between God and a woman.
The Rock, Christ’s Church, and the Keys
Jesus continued His answer to Peter by promising to build His church:
And I also say to you that you are Peter, and on this rock I will build My church, and the gates of Hades shall not prevail against it. And I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.” Then He commanded His disciples that they should tell no one that He was Jesus the Christ.
Jesus makes a wordplay between Peter’s name, Petros, and petra, the word for rock. Interpreters disagree about the rock’s identity: Peter himself, his confession, the truth revealed by the Father, or Christ.
Explanations of this passage often emphasize Caesarea Philippi’s pagan worship and imperial associations. Matthew identifies the region, but he does not say Jesus pointed to a temple or rock face to explain His meaning. He records Jesus’ question, Peter’s answer, and the Father’s revelation. Those words must govern the interpretation, even when the setting helps us picture the conversation.
Peter did have a foundational role as an apostle. He proclaimed Christ to Jews at Pentecost, ministered among Samaritans, and brought the gospel to Gentiles. Ephesians 2:20 describes the apostles and prophets together as the foundation, with Christ as the chief cornerstone. In 1 Peter 2, Peter directs believers to Christ as the living stone. His ministry established people in the truth about Jesus; he did not present himself as the one they must trust for salvation.
I understand Christ and the truth the Father revealed about Him to be the foundation on which He builds. Paul says that no other foundation can be laid than Jesus Christ (1 Corinthians 3:11). Peter served as an apostle who confessed and proclaimed Him. That real responsibility at the church’s beginning does not establish a transferable office through which a later bishop of Rome must govern the whole church.
The official Catholic Compendium, questions 182 and 185, identifies the pope as Peter’s successor with universal governing authority. It also describes infallibility in definitive teaching on faith or morals under specified conditions, rather than claiming that every personal opinion or decision of a pope is free from error. I do not find the continuing office or its claimed protection from error defined in Matthew 16. Jesus gives Peter an apostolic responsibility under His authority without establishing the claimed succession.
The Greek word ekklesia means an assembly or congregation. Jesus called it “My church.” He owns and builds it, preserving His redeemed people. Every apostle and later leader serves under His authority, without a right to replace His Word with private judgment.
The keys represent authority to open and close. Binding and loosing concern forbidding, permitting, or making an authoritative judgment. Peter received a genuine stewardship, expressed through apostolic proclamation and church discipline. He was not authorized to invent the terms of salvation or grant forgiveness independently of Christ’s blood.
I understand the grammar of binding and loosing to place heaven’s authority first. The NET translation of Matthew 16:19 reflects the construction by describing what will have been bound or released in heaven. Peter was to act in agreement with God’s judgment; he could not oblige heaven to approve whatever he decided.
In Matthew 18, Jesus also uses binding and loosing when He tells the gathered disciples how to deal with sin. Leaders who teach and exercise discipline remain accountable to His Word. They would abuse that responsibility by demanding allegiance to themselves, putting tradition above Scripture, or concealing wrongdoing.
Hades is the realm of the dead. Its gates picture the power of death, which cannot finally conquer Christ’s church because it cannot hold the risen Lord or permanently retain His people. The promise does not make every congregation or institution bearing a Christian name permanently faithful. Christ preserves the people who belong to Him.
The Suffering Messiah and the Call to Follow Him
The Lord who promised to build His church then explained that He would suffer and die. Peter had identified the promised King but had not accepted the path that King would take. Jesus would reign bodily and fulfill God’s promises, but rejection, death, and resurrection had to come first. Mark records His explanation and Peter’s response:
And He began to teach them that the Son of Man must suffer many things, and be rejected by the elders and chief priests and scribes, and be killed, and after three days rise again. He spoke this word openly. Then Peter took Him aside and began to rebuke Him. But when He had turned around and looked at His disciples, He rebuked Peter, saying, “Get behind Me, Satan! For you are not mindful of the things of God, but the things of men.”
Jesus spoke openly about His rejection by the elders, chief priests, and scribes, His death, and His resurrection. These events “must” happen because they belonged to God’s settled plan of redemption. He was explaining what He had come to accomplish, rather than admitting defeat or conceding that events had escaped His control.
His announcement helps explain why He temporarily forbade the disciples to publicize His identity (Mark 8:30). People could call Him Messiah while expecting Him to fulfill political hopes on their terms. The cross and resurrection would reveal the saving work they did not yet understand. His temporary instruction cannot be used as a permanent command to withhold the gospel.
Peter took Him aside and rebuked Him. He had just confessed the Christ and was now contradicting what the Christ said He must do. Jesus identified that outlook with Satan’s opposition: “Get behind Me, Satan!” He was not saying Peter was literally the devil or had ceased to be a disciple. Peter had become a stumbling block by opposing God’s purpose with human priorities.
Matthew records Peter’s objection (Matthew 16:21-23) and then the Lord’s instruction to all the disciples:
Then Jesus said to His disciples, “If anyone desires to come after Me, let him deny himself, and take up his cross, and follow Me. For whoever desires to save his life will lose it, but whoever loses his life for My sake will find it. For what profit is it to a man if he gains the whole world, and loses his own soul? Or what will a man give in exchange for his soul? For the Son of Man will come in the glory of His Father with His angels, and then He will reward each according to his works. Assuredly, I say to you, there are some standing here who shall not taste death till they see the Son of Man coming in His kingdom.”
Peter insisted that the suffering Jesus predicted would never happen. His true confession had not made every subsequent judgment correct. I need to recognize the same danger when I use a biblical title but refuse Scripture’s explanation of it. Jesus must define His Messiahship for us, including His suffering and saving death, His bodily resurrection, and His coming glory. The study on The Apostle Peter follows Peter’s continuing need for the Lord’s correction.
Jesus then called those who would follow Him to deny themselves and take up their cross. A cross meant shameful execution to His first hearers, so an everyday annoyance cannot exhaust His meaning. Loyalty to Him could cost them approval, possessions, safety, or even life itself. We follow the One who suffered, without making obedience conditional on keeping every comfort we want.
Our cross does not pay for sin or supply something missing from Christ’s sacrifice. His blood alone secures forgiveness; we obey because we belong to Him, rather than offering another atonement through our suffering. Jesus also warns that gaining the whole world cannot compensate for losing our soul. By His measure, a life that looks completely successful can end in catastrophic loss.
The Son of Man will return in His Father’s glory with His angels and repay each person according to his works. His judgment means our decisions have consequences beyond the present. We trust Him as Savior while acknowledging that He is also the Judge to whom we must answer.
Jesus also said that some standing there would see the Son of Man coming in His kingdom before they died. Matthew immediately follows with an event six days later:
Now after six days Jesus took Peter, James, and John his brother, led them up on a high mountain by themselves; and He was transfigured before them. His face shone like the sun, and His clothes became as white as the light. And behold, Moses and Elijah appeared to them, talking with Him. Then Peter answered and said to Jesus, “Lord, it is good for us to be here; if You wish, let us make here three tabernacles: one for You, one for Moses, and one for Elijah.” While he was still speaking, behold, a bright cloud overshadowed them; and suddenly a voice came out of the cloud, saying, “This is My beloved Son, in whom I am well pleased. Hear Him!”
On the mountain, Peter, James, and John saw Jesus’ face shine like the sun and His clothes become white as light. Moses and Elijah appeared with Him, and Peter proposed three tabernacles, or shelters. The Father’s voice singled out His beloved Son with the command, “Hear Him!” Moses and Elijah were God’s servants, but Jesus possessed an authority they did not share.
I understand the Transfiguration as a preview of kingdom glory that fits the promise Jesus had just given. His public return and earthly reign had not already occurred. The three disciples saw glory in the same Messiah who had told them He would suffer. Becoming truly human had never diminished His deity, and the Father’s command to hear Him included His unwelcome announcement of the cross.
The Wider Witness to the Eternal Son
Peter’s confession agrees with the wider testimony Jesus gave about Himself. During a confrontation recorded in John 8, His opponents challenged His authority and His relationship with the Father:
“Your father Abraham rejoiced to see My day, and he saw it and was glad.” Then the Jews said to Him, “You are not yet fifty years old, and have You seen Abraham?” Jesus said to them, “Most assuredly, I say to you, before Abraham was, I AM.” Then they took up stones to throw at Him; but Jesus hid Himself and went out of the temple, going through the midst of them, and so passed by.
After Jesus said Abraham had rejoiced to see His day, His opponents objected that He was not yet fifty years old. He answered, “before Abraham was, I AM.” His answer went beyond saying He was older than He looked. Abraham had come into existence, while Jesus described His own existence in absolute terms.
The Greek ego eimi can identify a speaker in ordinary conversation, so I would not detach those two words from their context and ask them to establish the entire doctrine of Christ’s deity. Here Jesus solemnly claimed existence before Abraham in language recalling God’s self-revelation. His hearers tried to stone Him. John had already identified the Word as God and Creator, and this declaration agrees with that testimony to the eternal Son.
Later, while Martha was grieving the death of her brother Lazarus, Jesus called her to believe in Him as the giver of life:
Jesus said to her, “I am the resurrection and the life. He who believes in Me, though he may die, he shall live. And whoever lives and believes in Me shall never die. Do you believe this?” She said to Him, “Yes, Lord, I believe that You are the Christ, the Son of God, who is to come into the world.”
Martha’s confession of Jesus as the Christ and the Son of God closely echoes Peter’s answer. Her brother was still dead, and Jesus had told her more than that He could perform a resurrection: “I am the resurrection and the life.” He was directing her to Himself as the source of life. She trusted Him while she was still grieving, before He called Lazarus from the tomb.
That promise did not exclude the physical death of believers. Lazarus had died, and Christians continue to die unless they are alive when Christ returns. Jesus guarantees bodily resurrection and everlasting life beyond death’s temporary reach. We trust that promise without claiming that every present grief must end as we would choose.
At His trial, Jesus was again asked directly whether He was the Christ and the Son of God:
But Jesus kept silent. And the high priest answered and said to Him, “I put You under oath by the living God: Tell us if You are the Christ, the Son of God!” Jesus said to him, “It is as you said. Nevertheless, I say to you, hereafter you will see the Son of Man sitting at the right hand of the Power, and coming on the clouds of heaven.”
Under oath, Jesus affirmed that He was the Christ and the Son of God, then spoke of the Son of Man sitting at the right hand of Power and coming on the clouds. His answer brings together Psalm 110 and Daniel 7. The prisoner before the court was telling His accusers that they would see Him exercising divine royal authority.
The high priest tore his clothes and called Jesus’ answer blasphemy. The accusation shows that the court understood an extraordinary claim, but it does not prove the claim false. They spat on Him and struck Him while mocking Him as the Christ (Matthew 26:65-68). He endured the suffering He had foretold; fulfilling Scripture did not excuse the cruelty of those inflicting it.
After His death and bodily resurrection, Thomas also had to answer who Jesus was:
Then He said to Thomas, “Reach your finger here, and look at My hands; and reach your hand here, and put it into My side. Do not be unbelieving, but believing.” And Thomas answered and said to Him, “My Lord and my God!” Jesus said to him, “Thomas, because you have seen Me, you have believed. Blessed are those who have not seen and yet have believed.” And truly Jesus did many other signs in the presence of His disciples, which are not written in this book; but these are written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His name.
Thomas had demanded to see the marks of crucifixion before accepting the other disciples’ testimony (John 20:24-26). Jesus appeared among them, invited him to inspect His wounds, and commanded him to stop being unbelieving. Thomas answered Jesus directly: “My Lord and my God!” Jesus accepted his confession as belief, then blessed those who would believe without seeing what Thomas had seen.
John tells us why he recorded the signs: that readers might believe Jesus is the Christ and the Son of God and have life in His name. We do not have to invent our own answer to Jesus’ question. The testimony God has given makes Him known so that we can trust Him.
Paul likewise says all things were created through Christ and for Him, that He existed before them, and that all fullness dwells in Him. In Hebrews, Paul identifies the Son as the Maker of the worlds who upholds everything and perfectly expresses God’s person. The study on The Deity of Jesus examines these passages more fully.
Peter’s later preaching directs people to the Lord he confessed. He calls Jesus the Holy One and the Just, the Prince of life in Acts 3:14-15, and the rejected cornerstone in Acts 4:11. The apostles agree in testifying to the divine Son who truly became man, died for sins, rose bodily, reigns now, and will return. Teaching that He was created contradicts their testimony and changes the identity of the One they call us to trust.
Saving Faith Trusts the Son Who Died and Rose
An ordinary prophet directs people to God; Jesus calls people to trust Him for eternal life. Scripture identifies Him as Creator and commands angels to worship Him. That testimony cannot be reconciled with making Him an angel, a created god, or one religious teacher among many. The study on Jesus Is the Truth considers why incompatible answers about Him cannot all be true.
Correct facts about Jesus do not by themselves establish saving faith. Demons knew facts about Him, and someone professing faith falsely can call Him “Lord.” We must trust the Jesus Scripture reveals. Yet Peter’s incomplete understanding also keeps me from requiring an advanced theology examination before someone can be saved. He truly confessed Christ while still needing correction. Trusting the Son presented in the gospel does not mean we already understand every implication of what we believe.
In repentance we turn from sin and unbelief toward God, and in faith we rely on Christ. Confession expresses that faith openly without earning His grace. A settled refusal to acknowledge Jesus reveals rejection of His identity and authority. Peter later explained the saving work of the Lord he had confessed:
For to this you were called, because Christ also suffered for us, leaving us an example, that you should follow His steps: “Who committed no sin, Nor was deceit found in His mouth”; who, when He was reviled, did not revile in return; when He suffered, He did not threaten, but committed Himself to Him who judges righteously; who Himself bore our sins in His own body on the tree, that we, having died to sins, might live for righteousness–by whose stripes you were healed. For you were like sheep going astray, but have now returned to the Shepherd and Overseer of your souls.
Jesus is fully God and fully man, born of a virgin and without sin throughout His life. He willingly gave Himself to be slain as the perfect sacrifice for our sins; His atonement rests on His perfection and that voluntary offering. Wicked people inflicted His bodily suffering and death. Through His shed blood and death He completed His saving sacrifice before He was buried and rose bodily. The Father did not punish, curse, abandon, strike, bruise, or pour wrath on His Son. The Father, Son, and Holy Spirit are distinct divine Persons who acted in unity for our salvation.
Christ died for the sins of the whole world, making God’s offer of salvation genuine for every person. His grace can be resisted and rejected, but everyone who repents and believes in Jesus receives forgiveness and eternal life. God gives that believer new birth, making him a new creation. The Holy Spirit indwells and seals him, and he remains eternally secure in Christ.
That security gives us no permission for lawlessness. Calling ourselves Christians cannot establish that we have been born again; our conduct should show evidence of new life. Obedience neither earns salvation nor keeps us saved. It expresses the life God gives through the Son we confess.
My Final Thoughts
Peter’s confession and the correction that followed leave me with more to consider than whether I know Jesus’ titles. I can speak truly about Him and still resist what He says when it overturns my expectations. I need to receive the Christ who explains His own cross and resurrection, builds His church, and promises to return in glory. The eternal Son who became truly human is the Savior I trust for life. Confessing Him also calls me to hear His Word when it corrects the kind of Savior or Lord I would prefer.
