"Get behind me, Satan!" (Matthew 16:23)
by Fr. Thomas Kagumisa | 08/27/2026 | Weekly ReflectionEsteemed parishioners of the Blessed Sacrament and Visitors,
After Peter publicly declared his faith in Jesus, as we heard in last Sunday's Gospel, Jesus told His disciples that He needed to go to Jerusalem to suffer at the hands of the elders and chief priests and ultimately be killed. Peter took Jesus aside and began to rebuke Him, saying, "God forbid it, Lord!" (Matthew 16:22). In this instance, Peter's human weakness was evident.
Peter expected the Messiah to be a king, a powerful authority in this world. He anticipated that Jesus would sit on the throne of David and liberate the nation of Israel from its oppressors. Consequently, Peter spoke from a human perspective. However, Jesus was not the kind of Messiah Peter envisioned. As the Prophet Isaiah had foretold, He was the Redeemer—despised and forsaken by men—who needed to bear our sufferings, be pierced for our transgressions, and be crushed for our iniquities (ref. Isaiah 53:3-5). This was Jesus' primary mission: to save us through his suffering, death, and resurrection.
"Get behind me, Satan,"Jesus said to Peter, "You are a stumbling block to me, for you are setting your mind not on divine things but on human things" (Matthew 16:23). Our Lord referred to Peter as Satan because, like the tempter in the desert, he was attempting to lead Jesus away from the path of the Cross towards earthly glory and power.
Recall that during the temptation in the desert, Satan took Jesus to a high place and showed Him all the kingdoms of the world. He said, "To you, I will give all this authority and their glory, for it has been delivered to me, and I give it to whomever I will. If you, then, will worship me, it will all be yours" (Luke 4:6). Jesus responded, "It is written, You shall worship the Lord your God, and him only shall you serve." Following this encounter, the gospel tells us, "And when the devil had ended every temptation, he departed from him until an opportune time" (Luke 4:13).
This opportune time appears in today's gospel, as Satan returns to tempt Jesus again, this time through Peter. He tried to persuade Jesus to reject the Cross, suffering, and humiliation, urging Him instead to seek earthly glory, prestige, honor, and respect. Jesus had to firmly reject this temptation to fulfill His mission of saving humanity through the Cross.
Peter's intentions were not inherently evil. He loved Jesus and didn't want Him to suffer. However, Jesus recognized that Peter's words could fulfill Satan's purpose because they contradicted God's saving will.
We shouldn't blame Peter; we might act similarly. We can unintentionally become instruments of Satan's work when we allow our human desires, fears, or worldly values to oppose God's will. For instance, we may discourage someone from obeying God because doing so is costly. Peter essentially said, "Lord, this suffering must not happen to You."We might do something similar when we tell someone, "Don't sacrifice so much," "Don't give too much to the church," "Don't forgive that person," or "God wouldn't ask you to suffer like that."
We often prioritize our desire to protect loved ones over their call to faithfulness. Genuine compassion can sometimes become spiritually dangerous. We want to shield those we care for from suffering, failure, rejection, sacrifice, or hardship, which can lead us to encourage them to take the easier path. However, Christian love doesn't only ask, "How can I prevent this person from suffering?" It also asks, "How can I help this person remain faithful to God?"
We often resist the idea of the Cross because we desire a Christianity that is free from suffering. As a follow-up response to Peter's reaction, Jesus clearly states, "If anyone would come after me, let him deny himself and take up his cross and follow me" (Matthew 16:24).
There is a deep connection between verses 23 and 24. Peter rejected the way of the Cross for Jesus, and in turn, Jesus proposed the way of the Cross for his followers. As Christians, we can unknowingly do Satan's work when we preach a Christianity of comfort without sacrifice, blessings without obedience, resurrection without dying to self, and glory without the Cross.
The fundamental lesson Jesus intends to convey is that divine salvation involves a constant struggle against sin and must pass through the mystery of the Cross. This is the essential law of life that Jesus proposes to His disciples.
To deny ourselves means to make sacrifices, including sacrificing our comfort and convenience, as well as our unwanted and sinful pleasures. We are called to devote ourselves to the good of our souls. This endeavor is morally and spiritually demanding and can feel like a cross to bear. However, Jesus wants us to carry this cross to demonstrate our faithfulness and love for Him. May God strengthen our resolve to carry these crosses in our lives and follow Christ.
In God's service and yours.
