to give light: to light up a place, to bring hidden things into the open, or to open a person's mind to divine truth
This verb covers a single idea, giving light, stretched across three settings. At its plainest it means to light up a place or a person the way a lamp or the sun does. From there it reaches to bringing hidden things out into the open, so that what was concealed becomes visible and known. And at its deepest it means opening someone's mind or heart to God's truth, the way sunrise floods a dark room.
The reason one word carries all three is Jewish, not Greek. When Alexandrian scholars translated the Hebrew Scriptures into Greek, they used this same verb both for God's word "causing light to shine" and for "teaching" or giving instruction (the Hebrew verb הוֹרָה, the root behind the word "Torah"). Light and teaching were welded together in the Greek Bible that the New Testament writers knew, so "to enlighten" a person and "to instruct" a person were nearly the same act.
That inheritance shows why, for the New Testament writers, being enlightened is less about a private mystical glow and more about coming into the light of what God has made known. When Paul prays that the eyes of the heart may be enlightened, or when Hebrews describes readers as "once enlightened," the background is the Psalms and the wisdom writings, where God's commandment "enlightens the eyes" and wisdom "makes a person's face shine."
Nuances
How the true light "enlightens every man": whether it shines on each person as objective revelation that demands a response, or inwardly illumines everyone.
- majorityThe light shines on every person as truth confronting them, forcing the decision of faith or unbelief, rather than inwardly illumining everyone.; Raymond E. Brown, The Gospel According to John I-XII, Anchor Bible 29 (1966); D. A. Carson, The Gospel According to John, PNTC (1991)
- minorityThe Word grants a general inner illumination to the whole human race.; Leon Morris, The Gospel According to John, NICNT rev. (1995)
Whether "enlightened" in Hebrews already carries the technical Christian sense "baptized," or means conversion and coming to know the truth, with baptism only an accompanying moment.
- majorityIt means coming into the knowledge of the gospel truth (compare Hebrews 10:26); it is not yet a technical term for baptism, a usage no first-century writer attests.; Paul Ellingworth, The Epistle to the Hebrews, NIGTC (1993); Harold W. Attridge, Hebrews, Hermeneia (1989); William L. Lane, Hebrews 1-8, WBC 47A (1991)
- minorityIt already trades on baptismal overtones, naming the decisive, unrepeatable moment of Christian initiation.; George R. Beasley-Murray, Baptism in the New Testament (1963); F. F. Bruce, The Epistle to the Hebrews, NICNT rev. (1990)
