SIBI-P1 G166-04
the age-abiding (thing)
| Root | αἰώνιος (aiōnios) |
| Core Meanings | age-long, age-abiding, perpetual, belonging to an age |
| Semantic Range | lasting for an age, perpetual, enduring, eternal, belonging to the age to come, world-related (in certain contexts) |
| Conceptual Significance | In biblical theology, αἰώνιος often contrasts the present age with the age to come, marking realities that partake in or characterize the coming age of God’s reign. It shapes key doctrines such as "age-abiding life" and "age-abiding judgment," emphasizing covenantal destiny and eschatological fulfillment rather than merely abstract endless duration. |
| Morphological Notes | Adjective, accusative singular (ANS = accusative neuter singular; AFS = accusative feminine singular). It agrees with a feminine or neuter noun in the accusative case, describing the direct object of a verb. |
| Rendering Rationale | The adjective derives from αἰών ("age, epoch"), so "age-abiding" preserves the root idea of enduring through or pertaining to an age rather than abstract infinity. The form αἰώνιον is accusative singular (feminine or neuter in these occurrences), functioning as a direct object and thus rendered as "the age-abiding (thing)" to reflect its case and number. |
