As Jesus is the cornerstone upon which the Church is built, so are his teachings the unifying cornerstone of Christian doctrine.

The Setting of Matthew 18:15-20

Let’s remember that the setting in Matthew 18:15-20 is a time when the disciples were the Church. After the resurrection, the house church became the norm. Megachurches, such as the assembly on Pentecost, were and still are rare exceptions. So, taking most disputes to the whole church is not possible in larger assemblies, but the spirit of these instructions is applicable in many wonderful ways. Conflict will always be part of church life, as long as sin exists. Sometimes we can resolve things easily and sometimes we must separate for a time, like Barnabas and Paul (Acts 15:36-39) or the universal Church and our schisms through Christian history.

Living a Holy Life

Protestants, Catholics and Orthodox broadly agree on salvation. In the Bible, saving faith is evidenced by the fruit of good works (James 2:14-26; Matthew 3:10; 7:19; Matthew 21:43; Colossians 1:10; Ephesians 2:10). We can’t actually separate faith and works. Jesus said in Matthew 16:27 that God, “will reward each person according to what they have done.” We can’t take the free gift of salvation and do nothing with it. Salvation “by faith alone, but not a faith that is alone” is a convoluted way to avoid saying that Orthodox, Catholics and Protestants actually agree, that an evidence of salvation is in doing good works.

Losing & Gaining Our Souls

In Matthew 16:26 Jesus asks, “what can anyone give in exchange for their soul?” In plain English, what are our lives worth? The Greek word translated as soul or life is the same word, meaning breath. It is used metaphorically for our life, everything that makes us ourselves. It’s a great paradox. Selfishness is a losing life. Giving of ourselves for Christ, we find true life. What good is it if we selfishly gain the whole world, when in so doing we lose ourselves? God values our worth by the death of His Son. True life is found not in narcissistic selfishness but in sharing with God and our neighbors.

Lose Life to Save It

In Matthew 16:25 Jesus made the strange-sounding statement that “whoever desires to save his life will lose it, but whoever loses his life for My sake will find it.” It is counter-intuitive to our natural instincts. We do a lot to preserve our lives. How can Jesus ask us to give up our lives for his sake? Each of us actually has two lives and this riddle speaks of both. Jesus asks us to willingly lose this temporal life. In so doing we gain eternal life. He did not ask us to commit suicide, but give up our self-centered ways, take up our crosses of self-sacrifice and follow him.

Confession without the Cross

In Matthew 16:24 Jesus said, “If anyone desires to come after Me, let him deny himself, and take up his cross, and follow Me.” Peter had confessed Christ. His acknowledgment made him a rock of the Rock, and he received the keys to the kingdom of heaven. But his public confession was not enough. Like us, he was to carry his cross. Altar calls are a public confession of Christ, popularized by Charles Finney in the 19th century. They are not always successful for this same reason. After confession of Jesus Christ is living a Christian life which includes, repentance of sin, baptism and carrying our cross and following Him.

From Rock to Stumbling Stone

In Matthew 16:23 Jesus told Peter, “you are not mindful of the things of God, but the things of men.” Peter went from rock of the Rock to rock of stumbling very quickly indeed. He also did worse, denying Jesus. We all experience ups and downs in our faith journey. There are times when we look at events around us and cry out, “Lord; this shall not happen!” Being crucified, at least figuratively, is something that Christians will experience. Are we too tempted to lose faith or cry out to heaven in objection? Let’s not stumble but remember that carrying our own cross of crucifixion is part of the journey.

Opposing or Following Jesus

When Peter rebuked Jesus’ regarding his prophecy of his crucifixion, Jesus rebuked him saying, “Get behind Me, Satan!” Satan means “adversary.” Peter was opposed to Jesus’ plans. The word for “behind” is translated in the next verse as “follow” me. Jesus wanted Peter to quit being an adversary and get behind him and follow him. When we try to take the lead from Jesus, we are adversaries. When we create church rules in opposition to Jesus, we are adversaries. When we try to be more righteous than Jesus we are in opposition to him. In this story Jesus is also saying to us, “Back me up, you who are in opposition.”

Get Behind me Satan

We naturally want to protect others from possible suffering. Like Peter said to Jesus, do we also say, “No way”? Jesus’ reaction was blunt, “Get behind me Satan!” Have we tried to discourage children from what we imagined to be a poor career choice, when maybe it was their life’s calling, their purpose for being. It is an evil and diabolical thing to make a young person unhappy for life, merely for the sake of family expectations. We don’t want others to suffer, and so we tend to want to baby them. Yet, such good intentions may actually do more harm than good. Like Peter, we may be benefiting the devil.

The Cross Transcends Human Traditions

In Matthew 16:21 we read that, “Jesus began to show to His disciples that He must go to Jerusalem, and suffer.” Jewish Messiahs were traditionally conquering military heroes who saved Israel from enemies. Jesus went totally against that, prophesying his crucifixion. To Peter it seemed to be admitting defeat. Peter’s immediate response was to reprimand Jesus. A Messiah was supposed to conquer, to say take up your sword and follow me, not your cross. The Church of Jesus Christ needs ongoing reformation. We constantly need to pray for and follow His direction not lean on our human traditions. In Jesus, loss is gain, defeat is victory. The cross transcends tradition.

Whatever You Forbid/Permit

In Matthew 16:19 we read, Whatever you forbid on earth will be forbidden in heaven, and whatever you permit on earth will be permitted in heaven.” As Peter opened the kingdom of heaven by his declaration of faith, so do the descendants of the faith of Peter “declare the terms under which God forgives sin and allows entrance to the kingdom.”1 This is shared by all the Apostles in Matthew 18:18. Their decisions “will have been tied up” and “will have been untied.”2 This is not divine endorsement of mere human decisions but divine guidance, enabling each to be “the faithful steward of God’s prior decisions.”3

Tertullian’s View of the Keys

In Matthew 16:19 Jesus said, I will give you the keys of the Kingdom of Heaven.” Tertullian taught that the whole Christian faith is built upon Peter being the first to confess Christ. What about the keys? Tertullian believed that, ‘(Peter) himself, therefore, was the first to unbar, in Christ's baptism, the entrance to the heavenly kingdom...’ He reasoned that Peter’s confession gave him and any others who showed this same faith, the key to the kingdom, not human politics and a succession of popes in an exclusive church. Indeed, ‘from that time forward, every number (of persons) who may have combined together into this faith is accounted "a Church"’.

Pope Impossible

The Apostles of Jesus Christ were scattered far and wide. How reliable was communication between the Christians of India, Ethiopia, Turkey and Spain? Is it unrealistic to claim Peter’s authority over all these lands in a time when it would have been a matter of practical impossibility? Early church fathers did not interpret Matthew 16:19 as Rome later came to. Could it simply be that wherever the right faith is to be found, there are the keys to the kingdom? How can any one person have a monopoly on that faith? Is that why Paul wrote that no other foundation than Jesus Christ can be laid (1 Corinthians 3:11)?

The Gates of Hades

In Matthew 16:18 Jesus spoke of the church that the gates of Hades shall not prevail against it.” In Greek mythology, Hades is pictured as a place with strong gates that do not permit escape. In this context, Jesus most likely used the term as a metaphor for the grave. That which overthrows all other societies will not overthrow the church. Many have tried. Roman Emperors, Zoroastrians, Jews, Persians, Middle Eastern Muslims, Chinese, Indians, Japanese, Bhutanese Buddhists, Russian Communists, Mexican governments, Madagascans, Fascists, Nazis, and North Korean despots all failed to destroy the church. The grave has no power over those who know that they will rise from the dead.

Chrysostom’s View of Peter

Chrysostom did not believe Matthew 16:18 supported Papal succession. ‘Thou art Peter, and upon this rock will I build my Church;" that is, on the faith of his confession… He that has built His church upon Peter's confession...’ (1) Peter’s authority over all the world did not continue beyond his grave other than through those who confessed the same faith. "For other foundation can no man lay than that is laid, which is Jesus Christ....I have preached Christ, I have delivered unto you the foundation. Take heed how you build thereon, lest haply it be in vainglory, lest haply so as to draw away the disciples unto men." (2)

Augustine’s View of Peter

Augustine of Hippo wrote, Christ is the rock (Petra), Peter is the Christian people. For the rock (Petra) is the original name. Therefore Peter is so called from the rock; not the rock from Peter; as Christ is not called Christ from the Christian, but the Christian from Christ. "Therefore," he saith, "Thou art Peter; and upon this Rock" which thou hast confessed, upon this Rock which thou hast acknowledged, saying, "Thou art the Christ, the Son of the living God, will I build My Church;" that is upon Myself, the Son of the living God, "will I build My Church." I will build thee upon Myself, not Myself upon thee.’

Upon THIS Rock

Does the word “this” make Jesus’ statement “on this rock I will build My church” point away from Peter? It is a feminine Greek pronoun. If Rome’s argument about translating from Aramaic were correct, shouldn’t the meaning be made clearer not ambiguous? Why wouldn’t Jesus say, “upon you I will build my church”? Does the Greek grammar of the word “this” contradict Catholic dogma by directing our attention away from Peter as its intended meaning? What did it point to? Many early church Fathers said that “this rock” was Peter’s confession of faith, while others said it was Christ Himself. Is the grammar then clear that Peter was not the rock?

You are Peter

In Matthew 16:18 we read, I also say to you that you are Peter, and on this rock I will build My church.” Peter is “Petros” and rock is a feminine “Petra” in Greek. Rome says that the rock in Matthew 16:18 was the same word as Peter in Aramaic. Where is the evidence that this conversation was in Aramaic? People from Galilee commonly spoke Greek as well. Does internal linguistic evidence show Matthew was written in Greek and that Jesus most likely spoke in Greek? Are linguistic markers of a translation from an Aramaic conversation absent? Many early church Fathers did not agree with Rome’s interpretation of this.

Peter was Rocky not Pope

We are called Christians because we believe in Christ. We could also be called Rocks of the Rock of our salvation, Jesus. That’s how many early Church fathers saw Peter’s faith in Jesus who is the cornerstone in the Church’s foundation of prophets and apostles (Ephesians 2:20). Jesus nicknamed Cephas as Rock (Peter) just as followers of Christ are named Christian. There is nothing in Matthew 16:18 declaring Peter as first in succession of men carrying sole authority over the entire Church. Nothing in the Bible or in early church writings universally supports the dogma of a Roman papacy as the sole Christian authority throughout the rest of Church history.

Origen’s View of the Rock

Origen commented on Matthew 16:16 writing, ‘if we too have said like Peter, "Thou art the Christ, the Son of the living God," not as if flesh and blood had revealed it unto us, but by light from the Father in heaven having shone in our heart, we become a Peter, and to us there might be said by the Word, "Thou art Peter," etc. For a rock is every disciple of Christ of whom those drank who drank of the spiritual rock which followed them, and upon every such rock is built every word of the church… all bear the surname of "rock" who are the imitators of Christ...’

Who do We Say He Is

In Matthew 16:15 Jesus asked his disciples, “But who do you say I am?” The answer to that question defines us. Peter answered it and he was named after the Rock of our Salvation. Are we like Peter, rock of the Rock? Some things about God are revealed to us by God alone. What a shame that this passage is overshadowed by those who wish to promote their own flesh and blood church leadership. Yet, when we understand who Jesus is, when that is revealed to us from our Father in heaven, then we too are Rock of the Rock and we receive the keys to the kingdom of heaven.

Caesarea Philippi

In Matthew 16:13 we read, When Jesus came to the region of Caesarea Philippi, he asked his disciples, ‘Who do people say that the Son of Man is?’” Caesarea Philippi was a city built on a rock to honor Caesar Augustus who called himself the son of a god. The imagery and the contrast with brutal human leadership were evident. In contrast to Caesar, the leaders of the Church of God were not to elevate themselves above their fellows, but become servants of all. The authority of deciding church matters was given to Peter but not to him alone. Jesus later explained that the other Apostles also carried decision-making authority (Matthew 18:18). The rock we build Christian ministry on is Jesus Christ not people.

Why did you Doubt

Peter had attempted to walk on water. Jesus stretched out his hand to catch him. So, Jesus said in Matthew 14:31-33, “‘O you of little faith, why did you doubt?’ And when they got into the boat, the wind ceased.” Peter did a good thing, stepping out on faith. He did not continue in faith. This is not the devil’s temptation, a foolish leap from the temple mount (Matthew 4:5-7). That would be wrong. Stepping out of the boat and walking on water begins with a prayer request, followed by an invitation from Jesus to “Come.” Then, like the disciples we cry, “Truly You are the Son of God.”

Lord Save Me

After Peter’s impetuosity and Jesus’ granting his request to walk on water, he quickly began to doubt. We read in Matthew 14:30 “But when he saw that the wind was boisterous, he was afraid; and beginning to sink he cried out, saying, ‘Lord, save me!’” There is often a conflict between sight and faith. Faith is the evidence of things not seen (Hebrews 11:1). Moments like this come to all of us. We begin to sink in life’s stormy waters and realize that we have more zeal than faith. We have had our eyes on our tempestuous circumstances and not on Christ. Then we cry out, Lord, save me.

Peter walked on Water

In Matthew 14:28-29 we read that Peter asked Jesus to let him walk on water too, “So He said, ‘Come.’ And when Peter had come down out of the boat, he walked on the water to go to Jesus.” Some are bold like Peter and jump right in. There is no criticism of that personality here. There is an example of what someone can accomplish with God’s help in their initial rush of faith and desire to be with Jesus. Studies have shown that of all those who rush forward at modern forms of evangelistic rallies, only about 15% join a church and stay. Spontaneity is good. Perseverance is better.

Be of Good Cheer

In Matthew 14:27 after the disciples’ initial fear seeing Jesus walking on water we read, “But immediately Jesus spoke to them, saying, “Be of good cheer! It is I; do not be afraid.” In the midst of storm wind and waves, Jesus spoke. He must have been close to them. The boat is an ancient Christian symbol of disciples tossed to and fro with trials of faith, temptations and mistreatment. Yet, Jesus calms the storms and provides safety. In church architecture, the center is the nave, meaning ship. Noah was brought to safety (1 Peter 3:20-21), Jesus comes to our boat and carries us through the storms to eternity.

An Apparition

In Matthew 14:26 we read that, “when the disciples saw Him walking on the sea, they were troubled, saying, ‘It is a ghost!’ And they cried out for fear.” When God appeared on the mountain to ancient Israel they were afraid, and when Jesus walked on water, the disciples were afraid at first. Sometimes we may be afraid to invite God into our situations, yet we need to remember that like with Israel and the disciples, God shows up in such a manner because we are highly favored. As they thought that Jesus was an apparition, we too can think that Jesus is somebody else. But, He comes to bless.

Walking on the Sea

In Matthew 14:25 we read, “Now in the fourth watch of the night Jesus went to them, walking on the sea.” The fourth watch was the last night watch, from about 3am to sunrise. Sometimes in Christian life, Jesus allows us to go through most of the night before He comes to us. And when He does, He may come in the form of a miracle, a supernatural event that is beyond any natural explanation, like walking on water. God often chooses to intervene just before we lose hope, so as to not overly try us. In Job 9:8 we read, “He... treads on the waves of the sea.”

Tossed by the Waves

In Matthew 14:24 we read that “the boat was now in the middle of the sea, tossed by the waves.” The disciples were where Jesus had sent them but they seemed in trouble. Shallow lakes are known for dangerous storm waves. Sometimes when we believe with our whole hearts that we are where Jesus wants us, things seem to go wrong. We doubt our calling. Sometimes Jesus sends us to sea even though He knows a storm is coming. We face winds of false doctrine, waves of temptation, and storms of mistreatment. Jesus is not trying to hurt us, but teach us to walk by faith and not by sight.

Go before Him

In Matthew 14:22-23 Jesus told His disciples to “go before Him to the other sideHe went up on the mountain by Himself to pray.” Sometimes it’s as if He has also sent us forth alone. As God, Jesus is everywhere at all times, but sometimes it seems like He has sent us on ahead for some reason. Sometimes it’s because Jesus has a special miracle planned for us. The crowd wanted to make Jesus an earthly king. When seduced by worldly promotion that is not in God’s plan, find a solitary place to pray. Ask heaven to keep us from the egotism that leads us away from His will.

They all Ate and were Filled

In Matthew 14:20-21 as Jesus fed the huge crowd we read, “they all ate and were filled, and they took up twelve baskets full of the fragments that remained.” It reminds us of God’s providence in the wilderness. Communion reminds us of the one who provides our daily bread and the bread of eternal life, Jesus. Our weekly offering is like loaves and fishes. We ask God to multiply our efforts to feed way beyond our numbers. God will supply. We cannot provide what our community needs. We can only look to God’s Divine Providence. He allows us to assist in feeding His people and He multiplies our small offerings.
