### Core Meaning & Semantic Range
The Greek adjective στερεός (stereós, `{{G4731}}`) derives from the verb ἵστημι (histēmi, `{{G2476}}`), meaning "to stand" or "to cause to stand." This etymological root profoundly shapes its semantic range, emphasizing qualities of stability and immovability. In its most literal sense, στερεός refers to something that is "stiff," "solid," or "hard," contrasting with that which is fluid or soft. This is evident in its application to "solid food." Figuratively, the word extends to describe that which is "firm," "stable," "steadfast," "unwavering," or "sure." It conveys a sense of reliability, permanence, and resistance to change or external pressure. The core meaning thus encompasses both physical solidity and metaphorical steadfastness, denoting an unyielding and unshakeable quality.
### Biblical Occurrences & Contextual Analysis
The term στερεός appears in a few significant contexts within the New Testament, each highlighting a facet of its meaning:
* **Hebrews 5:12, 14**: Here, στερεός is used to describe "solid food" (βρῶμα στερεόν), contrasting it with "milk." In this context, the author uses a physical metaphor to speak of spiritual maturity. "Solid food" represents deeper theological truths and doctrines that require discernment and spiritual understanding, suitable for those "of full age" (τελείων). Conversely, "milk" signifies elementary teachings appropriate for spiritual infants. The implication is that mature believers should be capable of processing and applying στερεός doctrine, indicating a robust and developed spiritual state.
* **2 Timothy 2:19**: Paul declares, "Nevertheless the foundation of God stands firm" (ὁ στερεὸς θεμέλιος τοῦ θεοῦ ἕστηκεν). Here, στερεός describes God's foundation, emphasizing its unshakeable and enduring nature. This foundation is not merely stable but divinely established and therefore absolutely reliable. It speaks to God's unwavering faithfulness, His eternal purpose, and His secure election of His people, providing absolute certainty amidst human apostasy or doctrinal error.
* **1 Peter 5:9**: Peter exhorts believers to "resist him [the devil], firm in your faith" (στερεοὶ τῇ πίστει). In this instance, στερεός describes the quality of faith required to withstand spiritual opposition. It denotes a faith that is not easily swayed, compromised, or shattered by trials, temptations, or the schemes of the adversary. This "firm faith" is rooted in Christ and enables believers to stand resiliently against the forces of evil.
Across these occurrences, στερεός consistently points to an enduring, unyielding quality, whether it be spiritual maturity, divine reliability, or resolute faith.
### Related Words & Concepts
The semantic field of στερεός is enriched by its relationship to several other Greek terms and theological concepts:
* **ἵστημι (histēmi, `{{G2476}}`)**: As the root verb, it provides the foundational concept of "standing" or "being established." στερεός describes the state of being firmly stood or established.
* **στερεόω (stereóō, `{{G4732}}`)**: This is the verbal form, meaning "to make firm," "to strengthen," or "to establish." It highlights the process by which something becomes στερεός. For example, in Acts 3:7 and 16, the lame man's feet and ankles were "strengthened" (ἐστερεώθησαν), making him able to stand firmly.
* **ἑδραῖος (hedraios, `{{G1476}}`)**: Meaning "steadfast" or "immovable," this adjective often appears in contexts emphasizing unwavering commitment, particularly in 1 Corinthians 15:58, where believers are exhorted to be "steadfast, immovable." It shares a strong conceptual overlap with στερεός in its figurative sense.
* **ἀσφαλής (asphalēs, `{{G803}}`)**: Meaning "safe," "secure," or "certain," this term also conveys reliability and stability, often in the context of truth or historical fact (e.g., Luke 1:4; Acts 2:36).
* **Concepts**: The word στερεός is intricately linked to theological concepts such as divine immutability, the security of salvation, spiritual maturity, enduring faith, and the stability of God's kingdom and promises.
### Theological Significance
The theological significance of στερεός is profound, touching upon the nature of God, the character of faith, and the process of spiritual growth:
* **God's Unshakeable Foundation**: The declaration that "the foundation of God stands firm" ([[2 Timothy 2:19]]) is a powerful affirmation of God's immutable character and His sovereign control over His purposes. It assures believers that despite human frailty, apostasy, or external pressures, God's plan and His church are built on an unshakeable, divinely established bedrock. This speaks to His faithfulness, His election, and the ultimate security of those who belong to Him.
* **Spiritual Maturity and Discernment**: The metaphor of "solid food" ([[Hebrews 5:12, 14]]) underscores the biblical call for believers to mature beyond elementary teachings. To partake of στερεός food means to engage with deeper theological truths, to develop spiritual discernment, and to grow in understanding God's Word. It implies a robust spiritual constitution capable of distinguishing good from evil and navigating complex doctrines, moving from spiritual infancy to spiritual adulthood.
* **Resilient Faith**: The exhortation to be "firm in your faith" ([[1 Peter 5:9]]) highlights the active and enduring quality of true faith. It is not a passive assent but a resolute conviction that enables believers to withstand the fiery darts of the enemy and the trials of life. This στερεός faith is rooted in the person and work of Christ, providing an anchor for the soul in times of adversity. It signifies an unyielding trust in God's promises and power.
* **The Nature of Truth**: Implicit in the concept of "solid food" is the idea that divine truth is στερεός—it is substantial, reliable, and provides spiritual nourishment necessary for growth and stability.
### Summary
The Greek word στερεός (stereós, `{{G4731}}`), derived from ἵστημι (to stand), conveys a rich meaning of firmness, solidity, and steadfastness. Literally, it refers to "solid food," symbolizing mature spiritual doctrine that nourishes and strengthens the believer. Figuratively, it describes an unshakeable quality, whether applied to God's στερεός foundation, signifying His unchanging faithfulness and secure purposes, or to the believer's faith, which must be στερεός to resist spiritual adversaries. The word emphasizes stability, reliability, and immovability in both divine and human contexts. It underscores the call for spiritual maturity, the security found in God's character, and the necessity of an enduring, resilient faith that is firmly rooted in Christ.
