What Does the Word "Eternulo" Mean in 2 Cor 10:17?

"Eternulo" in 2 Corinthians 10:17 conveys not merely the attribute "eternal," but the divine name Yahweh, which Paul quotes from the Old Testament. Therefore, the word points to the Lord God in the context of Jeremiah’s prophecy; at the same time, this does not deny the full divinity of Christ and His unity with the Father.

The Apostle Paul concludes a thought about ministry, success, and human boasting with a brief quote: a Christian should not exalt himself, his gifts, or the fruits of his labor. In the Esperanto Bible translation, the word used here is Eternulo. To understand it properly, it is important to see where the quotation comes from and what function this word serves in translation.

What the Word Eternulo Means

In Esperanto, Eternulo literally means "the Eternal One." However, in Bible translation, this word is traditionally used as a special designation for the God of Israel—where the Hebrew original of the Old Testament contains the divine name YHWH, or Yahweh. Thus, it is not merely a description of God's attribute, but a translation equivalent for the divine name.

In 2 Corinthians 10:17, Paul is not introducing a new name for Jesus. He takes a statement almost verbatim from the book of Jeremiah. That is precisely why the Esperanto translator uses Eternulo: it shows the reader the Old Testament source of the quote and its connection to the Lord Yahweh.

“Let the one who boasts, boast in the Lord.” 2 Cor 10:17

Paul Quotes the Lord Speaking Through Jeremiah

In the broader context of Jeremiah, the Lord Himself explains what a person ought to boast about. Not about wisdom, strength, riches, or personal status, but about knowing God and His character. Here, Yahweh speaks in the first person: He exercises kindness, justice, and righteousness. Thus, the primary referent of the word Eternulo is the Lord God, who speaks in the prophetic text.

“‘Let him who boasts boast of this, that he understands and knows Me, that I am the Lord who exercises lovingkindness, justice and righteousness on earth; for I delight in these things,’ declares the Lord.” Jer 9:23–24

Therefore, the answer to the question "why not Christ?" is this: translation does not attempt to specify which Person of the Trinity is speaking in every Old Testament passage. It renders the divine name found in the source of Paul’s quotation. To label Eternulo as "Jesus" here would no longer be a translation of the word itself, but a theological clarification that the text does not directly make.

Does This Separate Christ from the Lord God?

No. The Bible teaches that the Father and the Son are not the same Person, yet the Son is fully God and perfectly reveals the Father. Jesus said that whoever has seen Him has seen the Father. This does not mean that Jesus is the Father, but that in His words, character, and redemptive work, God Himself is revealed.

“He who has seen Me has seen the Father; how can you say, ‘Show us the Father’?” John 14:9

The Adventist understanding of the Trinity upholds both biblical truths: there is one God, and the Father, the Son, and the Holy Spirit are three co-eternal Persons of the Godhead. Therefore, in a specific passage, the word Eternulo can designate Yahweh as the covenant God, without being an exclusive "name for the Father alone" and without denying the deity of the Son.

Ellen White also emphasized the eternal pre-existence and full divinity of Christ. In The Desire of Ages, she writes that in Christ is life, original, unborrowed, and underived. Yet such theological testimony does not alter the linguistic fact: in 2 Corinthians 10:17, Eternulo appears because of the quotation of Yahweh from Jeremiah.

How Paul Applies This Text to Christ

Even though Paul quotes the Lord God, he immediately links true boasting to salvation in Christ. A person cannot credit themselves with wisdom, righteousness, sanctification, or redemption. All of this is God’s gift, given through Jesus. Therefore, for a Christian, boasting in the Lord means thanking God for His grace revealed in Christ.

“It is because of him that you are in Christ Jesus, who has become for us wisdom from God—that is, our righteousness, holiness and redemption. Therefore, as it is written: ‘Let the one who boasts boast in the Lord.’” 1 Cor 1:30–31

Conclusion and Practical Application

In 2 Corinthians 10:17, Eternulo designates the Lord Yahweh, because Paul is quoting the book of Jeremiah, where God is named in this way. The word is not used as a specialized name for Christ in this verse. Nevertheless, Christ is not set aside: through Him, we come to know the Father, receive salvation, and can truly boast only in God’s grace.

Practically, this invites us to examine our motives: when we speak about ministry, knowledge, success, or spiritual experience, let us give glory not to ourselves, but to the Lord. May our greatest boast be not what we have done for God, but what God has accomplished for us in Christ.
