Children of Abraham or Children of the Devil? The Question of True Paternity (Part 2)
47He who is of God hears the words of God. For this cause you don’t hear, because you are not of God.”
John 8:47 presents Jesus's claim that those spiritually born of God recognize and receive his words, while those not of God lack the capacity to hear him authentically. The passage equates spiritual origin with receptivity, making the ability to hear Jesus's teaching a diagnostic marker of one's relationship to God and his kingdom.
You cannot hear God's word and refuse to obey it—your refusal is itself proof of where your deepest allegiances lie.
At the anagogical level, the verse points to the eschatological judgment: at the last day, the dead will hear the voice of the Son of God and those who hear will live (Jn 5:25). The capacity to "hear" Jesus now is a foretaste of and preparation for that final, life-giving hearing.
Catholic tradition illuminates this verse with particular depth on two fronts: the nature of divine filiation and the theology of the Word.
Divine Filiation and Grace: The Council of Trent and the Catechism of the Catholic Church (CCC 1996–1999) teach that justification is not merely a forensic declaration but a genuine interior transformation — a real participation in divine nature (cf. 2 Pet 1:4). To be "of God" in John's sense is precisely this: to have received sanctifying grace, to have been regenerated in baptism, and to be, in the words of St. Thomas Aquinas, capax Dei — capable of God. St. Augustine, in his Tractates on the Gospel of John (Tractate 42), directly addresses this verse: "Why do they not hear? Because they are not of God. Why are they not of God? Because they are unwilling to believe." Augustine refuses to let the verse collapse into a crude predestinarianism; the inability to hear is, for him, the consequence of a will that has hardened itself against grace. The verse thus speaks to both divine initiative and human responsibility — a balance characteristic of authentic Catholic soteriology.
The Word of God as Christ: The Second Vatican Council's Dei Verbum (§4) teaches that Christ "completed and perfected Revelation... through his total presence and self-manifestation." The "words of God" spoken in John 8:47 are not propositions to be evaluated but the self-communication of the eternal Logos. The Catechism (CCC 102) quotes St. Jerome: "Ignorance of Scripture is ignorance of Christ." To fail to hear the words of God in the person of Jesus is therefore the deepest spiritual poverty imaginable. St. John Chrysostom (Homilies on John, Homily 55) connects this verse to the necessity of moral preparation for hearing: "A wicked life," he writes, "is the greatest impediment to faith." Holiness, for Chrysostom, is not only the fruit of hearing the Word but a prerequisite for hearing it at all — consonant with the Beatitudes' promise that the pure of heart shall see God (Matt 5:8).
John 8:47 confronts the contemporary Catholic with an uncomfortable question: Am I genuinely hearing the Word of God, or merely processing information about it? In an age of religious content consumption — podcasts, social media theology, Bible study apps — the temptation is to substitute familiarity with Scripture for the surrendered listening Jesus describes. A person can know every verse of the Gospel of John and still fail to "hear" in the Johannine sense.
The practical challenge this verse poses is twofold. First, it invites an examination of conscience: Where is the Word asking something of me that I am resisting? What teaching of the Church — on mercy, on sexuality, on justice for the poor, on forgiveness of enemies — do I find myself unable to "hear," unwilling to let land in the depths of my will? That resistance is not merely stubbornness; Jesus says it reveals something about one's relationship to God.
Second, this verse is a call to cultivate the conditions for hearing: regular, unhurried lectio divina; frequent reception of the sacraments (which regenerate and sustain the life "of God" within us); and the company of the saints, whose lives demonstrate what receptive hearing looks like made flesh.
Commentary
John 8:47 — "He who is of God hears the words of God."
The Greek verb translated "hears" (ἀκούει, akouei) carries in Johannine usage a weight far beyond auditory perception. In John's Gospel, "hearing" is consistently linked to discipleship, faith, and eternal life (cf. Jn 5:24, 10:3, 10:27). To "hear" the words of God is to receive them into oneself, to be shaped by them, and ultimately to obey them — it is the Shema of Israel (Deut 6:4, "Hear, O Israel") transposed into a Christological key. The phrase "words of God" (τὰ ῥήματα τοῦ θεοῦ, ta rhēmata tou theou) is significant: Jesus does not merely report teachings about God or transmit divine commands secondhand. Throughout this entire discourse (John 8:12–59), he has claimed that his words are the Father's words, that he speaks only what he has heard from the Father (8:26, 8:28, 8:38). To refuse his words, therefore, is not a theological disagreement — it is a refusal of God himself.
The phrase "of God" (ἐκ τοῦ θεοῦ, ek tou theou) functions as a relational-ontological category throughout the Fourth Gospel. It denotes origin, family lineage in the spiritual sense, and the source from which one's life draws its vitality. John uses this construction to describe authentic believers: they are "born of God" (Jn 1:13), "born of the Spirit" (Jn 3:8), their works are "wrought in God" (Jn 3:21). To be "of God" is to share in the divine life through the regeneration that comes by faith and baptism.
"For this cause you don't hear, because you are not of God."
Jesus now turns the logic into a verdict. The causal structure is vital: the inability to hear is not an intellectual failing or a cultural misunderstanding — it is diagnostic of a spiritual condition. Their non-hearing is the evidence, the outward symptom, of an interior state: they are not "of God." This is the climax of the paternity argument that began at verse 38, where Jesus distinguished between those whose "father" is Abraham/God and those whose "father" is the devil (8:44). Jesus has systematically dismantled the presumption that biological descent from Abraham constitutes membership in the family of God. True filiation is spiritual, not ethnic. The adversaries cannot hear because they have not been regenerated, have not received the light (Jn 1:11–12), and remain in the bondage described in 8:34.
The Typological and Spiritual Senses
At the typological level, this verse recapitulates Israel's long history of prophetic rejection. The prophets thundered "Hear!" to a people who would not (Isa 6:9–10; Ezek 12:2; Jer 5:21), and Jesus stands in that prophetic succession — yet he transcends it, because he is not merely a messenger but the Word himself. The parable of the sheep also illuminates this verse from within the Johannine corpus: "My sheep hear my voice" (Jn 10:27). Those who belong to the divine flock possess a kind of spiritual attunement to the Shepherd's voice. Non-hearing is thus a sign of not belonging to the flock, not merely of stubbornness.
