Why Jesus Teaches in Parables
10The disciples came, and said to him, “Why do you speak to them in parables?”11He answered them, “To you it is given to know the mysteries of the Kingdom of Heaven, but it is not given to them.12For whoever has, to him will be given, and he will have abundance; but whoever doesn’t have, from him will be taken away even that which he has.13Therefore I speak to them in parables, because seeing they don’t see, and hearing, they don’t hear, neither do they understand.14In them the prophecy of Isaiah is fulfilled, which says, ‘By hearing you will hear, and will in no way understand; Seeing you will see, and will in no way perceive;15for this people’s heart has grown callous, their ears are dull of hearing, and they have closed their eyes; or else perhaps they might perceive with their eyes, hear with their ears, understand with their heart, and would turn again, and I would heal them.’16“But blessed are your eyes, for they see; and your ears, for they hear.17For most certainly I tell you that many prophets and righteous men desired to see the things which you see, and didn’t see them; and to hear the things which you hear, and didn’t hear them.
Matthew 13:10–17 explains why Jesus teaches in parables: the disciples have been given understanding of the kingdom's mysteries, while crowds without receptivity remain spiritually blind. Jesus illustrates that those open to God's word receive greater insight, whereas those closed to it lose even what they have, fulfilling Isaiah's prophecy of hardened hearts.
The Kingdom is not hidden from you by God's cruelty but revealed to you by your own willingness to draw near—and hardened hearts are the work of those who have chosen other rests.
Commentary
Matthew 13:10 — The disciples' question. The question "Why do you speak to them in parables?" arises immediately after Jesus has delivered the Parable of the Sower to a large crowd (13:1–9). The disciples notice a shift in Jesus' teaching method: he is no longer speaking plainly but through stories that require interpretation. The Greek verb elaleis ("you speak") is in the imperfect tense, suggesting an ongoing pattern the disciples have noticed, not merely this one instance. Their question is therefore both curious and urgent — they sense that something is being withheld from the crowd that is being given to them.
Matthew 13:11 — The mystery given and withheld. Jesus' answer pivots on the word mystēria — "mysteries." In Hellenistic usage this term referred to secret religious knowledge accessible only to initiates; in Jewish apocalyptic literature (Daniel, 1 Enoch), it referred to divine plans hidden in heaven and disclosed to chosen seers. Jesus transforms both usages: the mysteries of the Kingdom are not esoteric speculation but the concrete reality of God's reign breaking into history in his own person and work. The passive constructions "it is given" (dedotai) are divine passives — God is the one who opens understanding. This is not a meritocracy of the spiritually clever but a gift of grace, freely bestowed. Crucially, however, Jesus does not say the crowds are permanently excluded; he implies their exclusion is conditional on their present disposition.
Matthew 13:12 — The principle of spiritual abundance. This logion, which also appears in Matthew 25:29 (the Parable of the Talents) and Mark 4:25, articulates a spiritual economy that feels counterintuitive: the rich get richer and the poor get poorer. But Jesus is not speaking of material wealth. The "having" in question is receptivity — the openness of heart that has already welcomed some measure of the Word. Those who have welcomed even a little of God's self-disclosure will find that welcome deepened into abundance. Those who have closed themselves — who have "but do not really have" — will lose even the religious heritage they nominally possess. This is a sobering word for those who rest on inherited faith without personal conversion.
Matthew 13:13 — The purpose of parables stated. The Greek conjunction hoti here can mean either "because" (causal) or "that" (result). Matthew's use of hoti (unlike Mark's hina, which more strongly implies purpose) softens the predestinarian edge: Jesus speaks in parables because the crowds already see without truly seeing, not in order that they might not see. The parables respond to an already-existing condition; they do not create it. Yet parables are also not merely accommodations to blindness — they simultaneously veil and invite. A parable arrests attention, unsettles assumptions, and creates an opening for the hearer who is willing to press in and ask, as the disciples do.
Verses 14–15 — Isaiah's prophecy fulfilled. The quotation from Isaiah 6:9–10 is the longest verbatim citation of the Old Testament in Matthew's Gospel. Isaiah received his prophetic call in the year King Uzziah died (Is. 6:1), in a vision of God's overwhelming holiness. His commission was paradoxical: preach to a people whose hearing would be impeded by their very act of hearing. This was not a command to produce blindness but a prophetic description of what Isaiah's ministry would encounter — and what it would reveal about the human heart. Matthew sees this pattern repeating itself precisely in the ministry of Jesus. The people's kardia ("heart," v. 15) has grown epachynthē — literally "fattened," thickened, made dull. The image is of spiritual adiposity: a heart so insulated by comfort, tradition, and self-satisfaction that it can no longer feel the sharp edge of the Word.
Matthew 13:16 — The beatitude of the disciples. Jesus pronounces the disciples makarioi — "blessed," the same word that opens the Beatitudes (5:3–11). Their blessing is specifically located in their physical senses: eyes that see, ears that hear. This is striking. Jesus does not say their blessing lies in their superior intelligence or virtue. Their eyes and ears are blessed because they are directed toward him — toward the Word made flesh standing before them. The senses, properly ordered toward the incarnate God, become instruments of grace.
Matthew 13:17 — The longing of prophets and righteous ones. Jesus widens the horizon dramatically: not just Isaiah but "many prophets and righteous men" — the whole sweep of faithful Israel — strained forward toward this moment without reaching it. Abraham "rejoiced to see" Jesus' day (John 8:56); David sang of his descendant; Simeon waited in the Temple (Luke 2:25–32). The disciples stand at the hinge of history. They do not deserve this privilege; they inhabit it by grace and by proximity to the incarnate Son of God.
Catholic Commentary
Catholic tradition has read this passage through the lens of what the Catechism calls the "senses of Scripture" — particularly the distinction between those who read the Word only on the surface and those who, guided by the Holy Spirit and the Church, penetrate to its deeper meaning (CCC 115–119). The "mysteries of the Kingdom" given to the disciples correspond to what Origen called the pneumatikoi — the spiritually mature — who move beyond the literal sense to the allegorical and anagogical depths. Yet Catholic tradition, unlike some Gnostic readings, insists this knowledge is not for a spiritual elite but is offered through the Church's sacramental and catechetical life to all who are willing to be converted.
St. Augustine's commentary on this passage in De Doctrina Christiana emphasizes that the disciples' privileged understanding flows from their love — they drew near to Jesus, they asked, they persisted. "Our heart is restless until it rests in Thee" (Confessions I.1) captures why the crowds remain on the periphery: their hearts have found provisional rest in other things. The hardening Isaiah describes is not imposed from outside but is the solidification of a direction the will has already chosen.
St. Thomas Aquinas (Summa Theologiae I–II, q. 112, a. 3) would locate the "giving" of v. 11 firmly within the theology of actual grace: God moves the intellect and will toward truth without destroying freedom. The disciples are not compelled to understand; they are disposed — their prior acts of following Jesus have opened a capacity in them that is then filled by divine gift.
Vatican II's Dei Verbum (§ 2) speaks of God's revelation as a "dialogue of love" — God speaks so that humanity might have fellowship with him. Parables, in this light, are not obstacles but invitations to enter more deeply into that dialogue. The blindness of those who do not understand is ultimately a refusal of relationship, not a cognitive failure.
For Today
For Catholics today, this passage issues a challenging diagnostic question: which crowd do I belong to? It is entirely possible to sit in Mass week after week, to hear the Gospel proclaimed, to receive the sacraments — and still be among those who hear without truly hearing. The "fattening of the heart" Isaiah describes is not a condition of pagans alone; it threatens the baptized when faith becomes cultural habit rather than living relationship.
Jesus' parable-method itself offers a practical spiritual practice: linger with Scripture until it unsettles you. Parables are designed to resist quick comprehension. The discipline of lectio divina — reading, meditating, praying, and contemplating a Gospel text — is precisely the posture of the disciples: drawing near, asking questions, pressing in. Pope Francis urges Catholics in Evangelii Gaudium (§ 174) to approach Scripture with a heart "prepared to listen," not simply to extract information but to be encountered by the living Christ.
The beatitude of verse 16 is also an invitation to recover a sense of awe: you see what prophets longed to see. Every Catholic who receives the Eucharist, reads the Gospels, or enters a tabernacle stands closer to the fulfillment of Israel's hope than Moses himself did. That privilege should generate not complacency but burning gratitude.
