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
