MARK 9:38–41, JESUS TEACHES TRUE DISCIPLESHIP BEYOND EXCLUSIVISM
THE INCLUSIVE MISSION OF CHRIST AND THE REWARD OF HIDDEN GOODNESS
Introduction
Immediately after correcting the disciples’ ambition about greatness, Jesus addresses another subtle but dangerous misunderstanding: spiritual exclusivism. John, speaking sincerely yet narrowly, reports an incident where someone outside their group was casting out demons in Jesus’ name. Instead of rejoicing that evil was being defeated, the disciples tried to stop him because he did not belong to their circle. Jesus responds with clarity and pastoral wisdom, teaching that God’s work cannot be confined to human boundaries. The Kingdom of God is larger than our groups, ministries, or titles. What matters is fidelity to Christ and participation—however humble—in His saving mission.
Bible Passage (Mark 9:38–41)
John said to him, “Teacher, we saw someone driving out demons in your name, and we tried to prevent him because he does not follow us.” Jesus replied, “Do not prevent him. There is no one who performs a mighty deed in my name who can at the same time speak ill of me. For whoever is not against us is for us. Anyone who gives you a cup of water to drink because you belong to Christ, amen, I say to you, will surely not lose his reward.”
(Translation: New American Bible, Revised Edition)
Background
This teaching follows Jesus’ correction of the disciples’ desire for status and power. Mark deliberately places these passages together to show how ambition and exclusivity often go hand in hand. The disciples had been chosen personally by Jesus, sent on mission, and entrusted with authority. Yet instead of seeing this as a call to humble service, they began to see it as a badge of privilege. The incident John reports reveals an early temptation in the Church: to equate belonging to a group with possessing God’s grace. Jesus dismantles this misunderstanding and reveals a broader, more generous vision of God’s action.
Opening Life Connection
Even today, believers can fall into the trap of thinking, “God works only through us,” or “Only our way is valid.” This attitude can appear in parishes, movements, ministries, and even families. We may become suspicious of good done by others simply because it does not originate from our group. This Gospel invites us to examine whether we rejoice when good is done in Christ’s name—even when it happens beyond our familiar boundaries.
Verse-by-Verse / Phrase-by-Phrase Reflection
John begins earnestly: “Teacher, we saw someone driving out demons in your name”. The work described is undeniably good—evil is being overcome. Yet John adds the revealing reason for objection: “because he does not follow us.” The concern is not about truth or integrity, but about belonging. This shows how easily ministry can become territorial.
Jesus responds firmly but gently: “Do not prevent him.” Jesus refuses to allow jealousy or control to interfere with God’s liberating work. His authority is not threatened by others acting in His name.
He explains further: “There is no one who performs a mighty deed in my name who can at the same time speak ill of me.” Authentic action done in Jesus’ name carries an inherent orientation toward Him. Good done sincerely opens the heart toward Christ, even if full discipleship is still unfolding.
Then Jesus offers a principle that broadens the disciples’ vision: “Whoever is not against us is for us.” This does not deny the need for truth or commitment, but it rejects suspicion and rivalry. The Kingdom advances wherever Christ’s name is honored and evil is resisted.
Finally, Jesus brings the teaching down to the smallest gesture: “Anyone who gives you a cup of water to drink because you belong to Christ… will surely not lose his reward.” No act of kindness done out of love for Christ is insignificant. Even the simplest service, unnoticed by the world, is remembered by God. The Kingdom grows not only through dramatic works, but also through quiet fidelity.
Jewish Historical and Religious Context
In first-century Judaism, recognized authority was closely tied to belonging—whether to a rabbinic school or a prophetic circle. Unauthorized religious activity was often viewed with suspicion. Exorcism, in particular, was considered a sign of divine authority. By affirming the outsider’s action, Jesus challenges rigid boundaries and reveals that God’s power is not restricted to officially recognized groups. This reflects the prophetic tradition, where God often acted beyond expected channels.
Catholic Tradition and Teaching
The Church affirms that while the fullness of the means of salvation subsists within her, God’s grace is not limited by visible boundaries. Wherever Christ’s name is honored and love is practiced, God is at work. This passage supports the Church’s call to humility, cooperation, and discernment rather than rivalry. It also highlights the doctrine of merit: every good act done with love, even the smallest, has eternal value when offered in Christ.
Historical or Saintly Illustration
Saint Francis of Assisi rejoiced whenever Christ was preached or honored, even if it was done imperfectly or by those outside his circle. He believed that God could use any willing heart to spread the Gospel. His humility allowed him to see God’s work everywhere, not just within his own community.
Application to Christian Life Today
This Gospel challenges us to move from competition to communion. Do we rejoice when others do good, or do we feel threatened? Are we more concerned about “who did it” than “what good was done”? Jesus calls us to support all sincere efforts that serve truth, compassion, and human dignity in His name. At the same time, He reminds us that even simple kindness—offering a cup of water—has lasting value when done for Christ.
Eucharistic Connection
In the Eucharist, Christ gathers people of every background into one Body. We receive the same Lord, not as a reward for belonging to a particular group, but as a gift of grace. Nourished by His Body and Blood, we are sent to recognize Christ at work in others and to serve without jealousy or fear.
