1 Corinthians 13:12 Commentary: Mirror and Full Knowledge
Greek · 11 what the commentators say
Meaning in one sentence
Paul contrasts our partial, enigma-like knowledge of God now with the face-to-face vision to come. Analysis of mirror, enigma, and the aorist 'was fully known.'
Research Summary
- Meaning: Our present comprehension of God and His purposes is like a dim reflection in a metal mirror; one day we will see Him directly and know Him as thoroughly as He already knows us.
- Key words: Esoptron (mirror, not window); ainigma (riddle, obscure saying); epignōsomai (I will fully know, thorough knowledge); aorist epegnōsthēn (I was fully known, God's prior complete knowledge).
- Main debate: Whether the 'mirror' is a metaphor for indirect revelation (word, sacraments, creation) or a specific reference to the dimness of ancient metal mirrors; and whether the aorist 'I was known' refers to God's eternal election, Paul's conversion, or simply God's sovereign knowledge.
- Theological theme: Eschatology and epistemology, the partial nature of present revelation and the hope of the beatific vision, grounded in God's prior knowledge of believers.
- Best use: Comforting those who struggle with unanswered questions; correcting pride in theological certainty; focusing the church on the hope of Christ's return.

Porque agora vemos por espelho em enigma, mas então veremos face a face; agora conheço em parte, mas então conhecerei assim como sou conhecido.

Scholars' Consensus
Commentators agree this verse is Paul's climactic illustration of the limitation of our present knowledge compared with what awaits us. The word esoptron (mirror) refers to the polished metal mirrors of antiquity, which gave a dim and imperfect reflection. Vincent notes that Corinth was known for manufacturing these mirrors. The phrase en ainigmati (in an enigma), rendered 'dimly' or 'darkly', means a riddle or obscure saying. Paul is echoing Numbers 12:8 (LXX), where God says he speaks to Moses 'not in riddles,' establishing a contrast between indirect revelation and direct face-to-face encounter. The apostle presses further: our future knowledge will not be partial but epignōsis, thorough, complete knowledge. And the basis of that future knowing is God's prior, complete knowledge of us, expressed in the aorist epegnōsthēn, 'I was fully known.' As Wesley notes, we will know 'in some measure like God,' but only because He already knows us fully.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Mirror as means of revelation: Calvin, Gill: The mirror is the ministry of the word and sacraments, reflecting God who is otherwise invisible.
- Mirror as imperfect vision: Vincent, Clarke: The focus is on the dimness of the ancient metal mirror, emphasising the inadequacy of present sight.
- I was known as conversion: Meyer (noted by Cambridge): The aorist refers to the moment Christ took knowledge of Paul (cf. Galatians 4:9).
- I was known as eternal: Gill, Calvin: Refers to God's eternal foreknowledge or election (cf. 1 Corinthians 8:3).
What is clear: All traditions agree that Paul contrasts our present limited knowledge (however received) with a future direct, complete knowledge of God, and that our confident hope rests on God's prior and perfect knowledge of us.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Meaning of 'in a mirror' (esoptron) | The word denotes a mirror, not a window, and ancient mirrors gave imperfect reflections. | Some, like Barnes, consider that Paul may refer to translucent materials used in windows (lapis specularis), but most (Clarke, Vincent, Cambridge) insist on polished metal mirrors. The consensus is that the image is of indirect, imperfect vision. |
| Meaning of 'dimly' (en ainigmati) | It means 'in a riddle' or 'obscurely,' contrasting with clear revelation. | Whether the enigma applies primarily to prophecy (Calvin) or to all present knowledge, including the natural world. Calvin sees it as the ministry of the word; Gill includes creation. All agree it underscores present limitation. |
| The time of 'then' | Refers to the future consummation when 'that which is perfect is come' (v.10). | Some (Matthew Henry) see it as the state of glory after death; others (JFB, Calvin) as the Second Coming and the resurrection. Both positions agree it points to the age to come. |
| The aorist 'I was fully known' | It indicates God's prior knowledge of the believer is the foundation for future knowledge. | Meyer (cited by Cambridge) takes it as 'when Christ took knowledge of me' (conversion); another view (Gill, Calvin) sees it as God's eternal election or omniscience. Both affirm that God's knowledge is the cause of ours. |
Historical & Cultural Context
Paul writes to a church in Corinth, a city famed for its bronze and metalwork. Ancient mirrors were not glass but polished metal, brass, copper, or silver, requiring constant polishing to maintain a usable reflection. The esoptron was often small, handheld, and gave a reflection that could be blurry or distorted. This historical reality gives weight to Paul's image: our present knowledge of God is like peering into a polished disc that shows only a vague, inverted image. The word ainigma (enigma) reinforces the idea. In Greek culture, an enigma was a riddle, like the Sphinx's question, whose answer was hidden. The Septuagint uses the same word in Numbers 12:8, where God speaks to Moses 'not in riddles,' implying that other prophets received more obscure revelation. Jewish tradition held that Moses saw God more directly than any other. Paul draws on this tradition to say that even the clearest revelation we have now, prophecy, tongues, knowledge, is like a riddle compared to the unmediated vision to come. The phrase 'face to face' echoes passages like Genesis 32:30 (Jacob's encounter) and Exodus 33:11 (God speaking to Moses), where direct encounter with God was both awe-inspiring and life-altering. For Paul, the hope of seeing God 'face to face' is not a metaphor for intimacy but a promise of complete, unmediated knowledge. The early church understood this as the beatific vision, the direct contemplation of God's glory.
Textual Notes
The consulted sources note no significant textual variants for 1 Corinthians 13:12. The manuscript tradition is stable. The only minor variation is in the tense of the final verb: some manuscripts read the perfect egnōsmai instead of the aorist epegnōsthēn, but the aorist reading is strongly supported (UBS, NA) and carries the meaning of a completed action, God's full knowledge of Paul as a settled fact, viewed from the future standpoint.
Reception History
This verse has shaped Christian hope across the centuries. Tertullian described Paul's description of love as 'uttered with all the strength of the Spirit' (cited by Lange). In the patristic period, the verse was read as promising the beatific vision, the direct sight of God. Medieval theologians (Aquinas, Bonaventure) used it to distinguish the imperfect knowledge of faith from the perfect knowledge of glory. The Reformers, especially Calvin, saw the mirror as the Word and sacraments, through which God reveals Himself now, while awaiting the full revelation in Christ. In modern evangelicalism, the verse comforts believers wrestling with doubt and uncertainty, reminding them that partial knowledge is temporary and that being fully known by God is the ground of all knowing. The image of the mirror has also been used in hymnody, most notably in 'Now we see through a glass, darkly' (various settings).
Preaching This Verse
Three-point outline
- Present knowledge is indirect and partial. The mirror and the enigma show that our understanding of God and His ways is real but incomplete. Like an ancient mirror, it gives a true but muted image. We see enough to trust, but not enough to have all our questions answered.
- Future knowledge is direct and complete. 'Face to face' signals unmediated presence. What we now grasp in fragments will be seen whole. The verb epignōsomai (I will fully know) points to a thorough, intimate knowing that leaves nothing hidden.
- Our knowing rests on God's knowing us. The aorist epegnōsthēn, 'I was fully known', grounds our future knowledge in God's prior, eternal knowledge of us. We will know because we are already known completely.
Five-point outline
- The mirror's limitations, historical context of ancient metal mirrors.
- The enigma, our present understanding as a riddle we cannot fully solve.
- The contrast, 'now' vs 'then' in Paul's argument about love's permanence.
- The goal, face-to-face vision, the Christian hope of seeing God as He is.
- The foundation, God's full knowledge of us, which makes our future knowledge possible.
Illustration hooks
- Looking at a photo of a mountain vs standing at the summit. The photo is accurate but misses the scale, the wind, the light.
- Trying to understand a foreign film with subtitles, you get the plot, but you miss the nuance, the humour, the culture. One day you'll speak the language fluently.
- A video call with a loved far away: you see their face, but you can't touch them, can't read their full expression. The real reunion is longed for.
Questions your congregation is asking
- If God wants us to know Him, why doesn't He show Himself more clearly now?
- Does 'I will know fully' mean we will know everything, or just know God fully?
- How does being fully known by God change how I face my own failures and doubts?
Leading a Discussion
In this verse Paul caps his argument about love's supremacy by showing that even our most treasured spiritual knowledge is only a foretaste. The Corinthians prized eloquent speech and deep insight; Paul reorients them toward the hope of seeing Christ as He is. This passage invites us to hold our theology humbly while clinging to the promise of complete communion.
Discussion questions
- What does Paul's analogy of a 'mirror' suggest about the nature of our present knowledge of God? How did ancient mirrors differ from modern ones, and why does that matter?
- The word translated 'dimly' is literally 'in an enigma.' Why do you think Paul chooses this word from Numbers 12:8? What does it imply about the way God reveals Himself now?
- Paul says 'then I will know fully, even as I was also fully known.' Shift the emphasis: we will know because we are already known. How does being fully known by God shape your present life of faith?
- In what areas of your life do you most feel the 'mirror', the partial, puzzling nature of your understanding of God's ways?
- How does this verse help you respond to Christians who claim to have complete or definitive answers to complex theological questions?
- Paul's larger point in the chapter is that love outlasts knowledge and prophecy. How does this verse undercut pride in spiritual gifts while also giving hope?
- What would it mean for you to live today with the tension of 'now we see dimly' while eagerly awaiting 'face to face'?

What the Commentators Say
11 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke clarifies that the Greek word translated as "glass" actually means a mirror, not something to see through. In ancient times, mirrors were made of polished metal and gave an imperfect image. His point is that Paul describes our current spiritual knowledge as a dim, puzzling reflection rather than a direct, clear view.
Barnes' Notes on the Bible Protestant 1832
Barnes argues that Paul's "glass" refers to an imperfect transparent substance like thin stone or early glass, not a mirror. Looking through it gives an obscure view, contrasting with the clear sight of heaven. He also stresses that knowing as we are known means the manner of knowledge becomes direct and clear, not that we gain omniscience.
Calvin's Commentaries Reformed 1564
Calvin interprets the mirror as the ministry of the word and the required means by which God, who is otherwise invisible, reveals Himself to us. Our current knowledge is obscure, like an enigma or dark saying, fitting for our imperfect state. He also sees the created world as another mirror of God's glory.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentator notes that the mirror Paul mentions was made of polished metal, not modern glass, so its reflections were necessarily unclear. The phrase "darkly" is literally "in an enigma" or riddle, suggesting partial understanding. Paul also connects knowing fully to being already known by God from the beginning.
Geneva Bible Notes Reformed 1599
For nowe we see through a glasse darkely: but then shall wee see face to face. Nowe I know in part: but then shall I know euen as I am knowen.
Gill's Exposition of the Bible Baptist 1748
Gill draws on Jewish tradition to explain the apostle's contrast: the prophets saw through a spotted, dim glass, while Moses saw through a bright, clear one. In the same way, believers now see through the glass of the Gospel and ordinances, but this vision remains partial compared to the perfect, face-to-face knowledge of heaven. Even Paul knew only in part.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB emphasizes that our present knowledge of God is like a dim reflection in an ancient metal mirror, indirect and partial, compared with the direct vision we will have. He notes that even the clearest revelation given to Moses involved "dark speeches," and our knowing now is overshadowed by the fact that we are fully known by God.
Lange's Commentary Reformed 1857
Lange insists that the word translated "charity" actually means love (ἀγάπη), the root and spring of all virtues rather than a single virtue like almsgiving. For him, personal worth depends entirely on sharing in this divine love, not on any gift or sacrifice. Without it, even the most spectacular spiritual endowments are worthless.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry's key point is that charity, or love, outlasts every spiritual gift because it belongs to eternity itself. Prophecy, tongues, and knowledge are temporary tools for the church on earth, but love remains forever in heaven where all other gifts become unnecessary.
Vincent's Word Studies Evangelical 1887
Vincent emphasizes that the ancient metal mirror gave an imperfect image, clarifying that "darkly" literally means "in a riddle or enigma." The partial, obscure vision of the present contrasts with future full knowledge, where Paul will be fully known as God fully knows him now.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley stresses that even what God reveals to us now comes through a dim mirror, leaving much still hidden and puzzling. But in the life to come we will know directly and fully, in a manner that approaches how God knows us—with penetrating clarity and complete comprehension.
