Paul declares that God "hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life" (2 Corinthians 3:6). The "letter" here is not the text of Scripture itself but the law considered apart from the Spirit's enabling power — the law as mere external demand without internal transformation. The Mosaic covenant written on stone tablets condemned because sinners cannot keep it. The new covenant, written on hearts by the Spirit, gives life because the Spirit empowers obedience from within. Paul is not pitting the Old Testament against the New — he is contrasting the external ministry of condemnation with the internal ministry of righteousness (2 Corinthians 3:7-9).
LETTER: A written message. The literal or verbal meaning, as distinguished from the spirit or intent.
LETTER, n. [L. litera.] 1. A mark or character used as the representative of a sound. 2. A written message. 3. The literal or verbal meaning of an expression, as distinguished from the spirit or intended meaning. Webster understood the letter-spirit distinction as the difference between bare words and their deeper intent — a principle applicable in both law and theology.
• 2 Corinthians 3:6 — "The letter killeth, but the spirit giveth life."
• Romans 2:29 — "Circumcision is that of the heart, in the spirit, and not in the letter."
• Romans 7:6 — "We should serve in newness of spirit, and not in the oldness of the letter."
"The letter kills" has been weaponized to dismiss the authority of Scripture's actual words.
Progressive theology frequently quotes "the letter kills, but the spirit gives life" to dismiss the plain meaning of biblical texts they find inconvenient. This is a gross misuse of Paul's argument. Paul is not saying that the written Word of God is deadly and should be ignored in favor of subjective spiritual experience. He is contrasting the old covenant's ministry of condemnation (the law without the Spirit) with the new covenant's ministry of righteousness (the law written on hearts by the Spirit). The "spirit" in 2 Corinthians 3 is the Holy Spirit, not a subjective feeling that overrides the text. Using this verse to dismiss Scripture's clear teaching is the exact opposite of Paul's intent.
• "The 'letter' that kills is the law without the Spirit's power — not the written Word of God. Paul is not dismissing Scripture; he is exalting the new covenant."
• "When someone says 'the letter kills' to dismiss what the Bible plainly says, they are using Paul's words against Paul's meaning."
