Luke 4:38-39
The Power of His Word
After Jesus left the synagogue, he entered the house of Simon. Simon’s mother-in-law was afflicted with a severe fever, and they interceded with him about her. He stood over her, rebuked the fever, and it left her. She got up immediately and waited on them.
Reflection:
In today’s Gospel, we encounter the first mention of Simon—whose name Jesus would later change to Peter—in Luke’s account. Simon was likely present in the synagogue and witnessed Jesus cast out a demon from a possessed man. With a simple command, “Be quiet! Come out of him!”, Jesus revealed His divine authority. The people were astonished and exclaimed, “What is there about his word? For with authority and power he commands the unclean spirits, and they come out” (Luke 4:35–36).
Having seen His authority firsthand, Simon presumably spoke to Jesus about his mother-in-law, who was suffering from a severe fever. It is striking to imagine the moment of Simon’s first personal encounter with the Lord. Though Jesus, in His divine foresight, knew what Simon would one day become—the first pope entrusted with the spiritual authority of Heaven—Simon himself could not have foreseen how radically his life was about to change.
Upon entering Simon’s home, Jesus rebuked the fever. The Greek word used here, epitimaō, is the same word used in the previous passage when Jesus rebuked the demon. This deliberate parallel reveals that both the spiritual and physical realms are subject to Jesus’ command. What He rebuked were real evils and disorders: demonic possession as a violation of the soul and the fever as a natural affliction of the body.
Later in this Gospel passage, Jesus continues healing many who are sick and casting out demons. Once again, He rebukes the demons, silencing them and forbidding them to speak. Though they cry out, “You are the Son of God,” Jesus does not permit them to bear witness to Him. He has no need of demons to proclaim His identity. His revelation will come in His time, by His own design, especially through the Cross and Resurrection.
Jesus’ rebukes, whether uttered by a word, expressed through a gesture, or conveyed by His mere presence, are divine actions against evil. They are not expressions of wishful hope, but authoritative, efficacious commands. What He speaks comes to be. His word is not just powerful; it accomplishes what it declares.
Understanding this is foundational to our life of faith and our spiritual journey. When we turn to Christ with trust, we must believe that His word has the power to heal, to free, and to transform. He does not speak in vain. His authority extends to every dimension of our lives, body, soul, and spirit, and He desires to restore all that has been wounded by sin, suffering, or disorder.
One of the most tangible and powerful ways this takes place today is through the words of absolution spoken by the priest in the Sacrament of Reconciliation, a spiritual authority first given to Simon Peter and passed down through apostolic succession. The words of absolution are Christ’s words, words that rebuke sin and its effects, restoring the soul to grace and peace. They are divine actions that accomplish what they signify.
Though the words of absolution may be the clearest example, every Sacrament—Baptism, Confirmation, the Eucharist, Anointing of the Sick, Holy Orders, and Matrimony—conveys God’s grace and power through the efficacious word and action of Christ.
Reflect today on your own trust in the power of Jesus’ word. Do you believe He can rebuke the disorders in your life with divine authority? Do you turn to Him with confidence in the Sacraments, knowing that what He speaks, He accomplishes? Surrender all that afflicts you to the power of His Word, and allow Him to restore you to grace, relying especially on the sacramental authority given to Simon Peter and exercised by the priests who have followed after.
