The Greek word tekmḗrion, represented by G5039, refers to a token (as defining a fact) or a criterion of certainty. It appears only 1 time across 1 unique verse in the Bible, making its single usage highly significant in establishing the concept of an infallible proof.
The sole appearance of G5039 is in the context of Christ's post-resurrection ministry. After his passion G3958, he shewed G3936 himself alive G2198 by many infallible proofs Acts 1:3. These proofs were not momentary glimpses; he was seen G3700 by his followers over a period of forty G5062 days G2250, during which he was speaking of things pertaining to the kingdom G932 of God G2316.
Several related words from its context in Acts 1:3 help clarify the nature of this proof:
- G3936 parístēmi (to stand beside, i.e. (transitively) to exhibit, proffer, (specially), recommend, (figuratively) substantiate): This word, translated as "shewed," emphasizes the active and deliberate presentation of evidence by Christ himself.
- G2198 záō (to live (literally or figuratively)): This affirms the state that the proofs were intended to confirm—that Christ was truly alive after his death.
- G3958 páschō (to experience a sensation or impression (usually painful)): This word, translated as "passion," sets the necessary backdrop. The proofs are significant because they occurred after he had verifiably suffered and died.
The theological weight of G5039 is immense, despite its rarity. It establishes a critical foundation for Christian belief.
- Evidential Basis of Faith: The term anchors the resurrection not in abstract belief but in tangible, verifiable evidence. Christ provided a "criterion of certainty" to substantiate his claims Acts 1:3.
- Physicality of the Resurrection: The "many infallible proofs" included being physically seen G3700 over a sustained period of forty days G5062, confirming the bodily nature of his return.
- Authentication of the Kingdom Message: The proofs served to validate the messenger. By demonstrating he was alive, Christ authenticated his subsequent teaching about "the kingdom of God" Acts 1:3.
In summary, while appearing only once, G5039 is a cornerstone word. It defines the resurrection of Christ not as a mystical story but as a historically substantiated event confirmed by infallible proofs. This single term provides the "criterion of certainty" upon which the apostles' subsequent preaching and the message of the kingdom of God are built.
