Parathēkē pa-ra-THAY-kay
a deposit, something entrusted for safekeeping
“Someone Else's Property”
A man is leaving on a journey and cannot take everything with him. He carries what he owns to a neighbor’s house and leaves it there — silver, tools, a title, whatever will not travel. The neighbor takes it in. No money changes hands. There is no sale, no loan, no gift. There is only an arrangement, understood by both men and enforceable in court, that when the traveler returns the neighbor will hand back what he was given.
The Greek word for what was left is parathēkē.
Everything about the arrangement is defined by the fact that the goods are not the neighbor’s. He may not sell them. He may not spend them. He may not — and this is the part that has theological teeth — improve them. If the traveler comes home and finds his silver recast into a better design, the neighbor has not done him a favor. He has failed at the one thing he was asked to do.
Paul hands Timothy a parathēkē. He does not tell him to develop it, defend its reputation, or make it relevant. He tells him to guard it.
The Word
The Greek word is παραθήκη (parathēkē), pronounced in the Erasmian convention as pa-ra-THAY-kay, with the accent on the third syllable. It is a first-declension feminine noun.
The compound is transparent. Para (παρά) means beside or alongside; thēkē comes from the verb tithēmi (τίθημι), to place or to put. A parathēkē is literally a placing-beside — something set down next to someone for keeping. The English word that comes closest is the legal bailment, though deposit is what nearly every translation uses and is clear enough.
The word family runs through the New Testament even where the noun does not:
Paratithēmi (παρατίθημι) — the parent verb, to place beside. It carries both an ordinary sense and a technical one. Ordinarily it means to set food before someone (Mark 6:41; Luke 9:16) — the same gesture, a thing placed within reach of another. Technically it means to entrust: “to whom much has been entrusted, of him much more will be asked” (Luke 12:48); Paul and Barnabas entrusted the new elders to the Lord (Acts 14:23); Paul entrusts his charge to Timothy (1 Timothy 1:18). Most movingly, it is the verb on Jesus’ lips at the cross: “Father, into your hands I commit my spirit” (Luke 23:46), and Peter’s counsel to the suffering, who are to entrust their souls to a faithful Creator (1 Peter 4:19). To make a parathēkē is an act of trust in the one receiving it.
Phylassō (φυλάσσω) — to guard, to keep watch over. This is the verb that governs parathēkē in every one of its three appearances. It is a sentry’s word, not a scholar’s. The noun phylakē is a prison or a watch of the night.
Paradidōmi (παραδίδωμι) and paralambanō (παραλαμβάνω) — to hand over and to receive. Not cognates, but the same idea in verb form, and the pair Paul uses for the tradition of the gospel: “I received from the Lord what I also handed on to you” (1 Corinthians 11:23), “I handed on to you as of first importance what I also received” (1 Corinthians 15:3). The Latin translation of paradidōmi gives us the word tradition, which means, exactly and only, the thing handed over.
The Septuagint background is legal rather than religious, and this is the key to the word. In Leviticus 6:2–4 (5:21–23 in the Greek versification) the parathēkē is the property a man leaves with his neighbor, and the sin under discussion is denying that he ever received it. Exodus 22:7–13 legislates the same situation in detail: what happens if the deposit is stolen, what happens if an animal left in trust dies, who swears what oath before whom. This is property law. It is about the difference between what is yours and what is merely in your hands.
Paul reaches into that vocabulary to describe the gospel.
Range of Meaning
Parathēkē is rare — three occurrences in the New Testament, all of them in the Pastoral Epistles — and its range is correspondingly narrow.
A deposit left for safekeeping. The base legal sense, carried over from ordinary Greek and from the Septuagint’s property law. Nothing in the New Testament’s usage abandons this sense; the theological uses are built on it rather than replacing it.
The gospel entrusted to a minister. The dominant New Testament sense. In 1 Timothy 6:20 and 2 Timothy 1:14, what Timothy has been given to guard is the apostolic teaching itself — the content of the faith, received from Paul, to be kept intact and passed on.
What has been entrusted to God — or to Paul. 2 Timothy 1:12 is genuinely ambiguous in Greek, and honest translations disagree. Paul writes that he is convinced God is able to guard tēn parathēkēn mou — “my deposit” — until that day. A possessive genitive can point either direction. It may mean the deposit I have made with him: Paul has handed his life, his work, and his death over to God for safekeeping. It may mean the deposit he has made with me: the gospel Paul was given, which God himself will preserve. Compare the NET and the KJV against the ESV and NIV and you will find the disagreement in print. Both readings are grammatically available and both are theologically sound; the verse is one of the places where a translator has to choose and the reader deserves to be told that a choice was made. The immediate context, where verse 14 clearly means the gospel entrusted to Timothy, gives a mild edge to the second reading. It is an edge, not a proof.
Where You’ll Meet It
1 Timothy 6:20. “O Timothy, protect what has been entrusted to you.” In Greek the line is abrupt and personal — Ō Timothee, tēn parathēkēn phylaxon — a vocative and an aorist imperative, the last thing Paul says before the closing benediction. A long letter about elders and widows and money and false teachers ends by reducing the whole charge to five words. Whatever else the ministry is, it is this.
2 Timothy 1:12. “I am convinced that he is able to protect what has been entrusted to me until that day.” Written from prison by a man who knows how the trial will end. The confidence in the verse is not that Paul will hold on but that God will. Note the tense of the situation: a deposit is guarded across an interval, between the leaving and the returning. Paul names the far end of the interval — that day.
2 Timothy 1:14. “Protect that good thing entrusted to you, through the Holy Spirit who lives within us.” The same imperative as 1 Timothy 6:20, now with the means attached. The deposit is not guarded by vigilance, cleverness, or institutional machinery. It is guarded through the Spirit, and the Spirit is described as indwelling — the guard is posted inside the house.
2 Timothy 2:2. The noun does not appear, but the verb does, and this is the verse that keeps the whole metaphor from going wrong. “And what you heard me say in the presence of many others as witnesses entrust to faithful people who will be competent to teach others as well.” Parathou — the same root, now an imperative addressed to Timothy. Four links are visible in one sentence: Paul, Timothy, faithful people, others. The deposit is guarded by being moved. A treasure buried for safety is a treasure that has failed at its purpose, and Jesus told a parable about the man who tried it.
What Confessional Lutherans Hear
Parathēkē — a deposit, something entrusted for safekeeping
Three emphases.
Tradition means the thing handed over, not the thing added. Confessional Lutherans have a peculiar relationship to the word tradition, having been accused of both too much and too little of it. The parathēkē vocabulary clarifies what is actually claimed. The Apology of the Augsburg Confession makes the claim constantly and almost monotonously: we are teaching nothing new. The Formula of Concord’s Rule and Norm places Scripture as the single judge and the Confessions as a witness to what has always been taught from it. Neither document presents Lutheran doctrine as a discovery. Both present it as a deposit-return — here is what we were given, unaltered, and here is the receipt. The Reformation’s self-understanding is the neighbor opening the storehouse and showing that nothing has been spent.
This cuts in both directions, which is why it is worth teaching. It cuts against the church that develops doctrine beyond what was handed over. It cuts equally against the congregation that treats the faith as a local product, refreshed every few years to suit the audience. Neither is guarding a deposit. Both are recasting the silver.
The office is a trusteeship. Augsburg Confession XIV insists that no one should teach or administer the sacraments publicly without a proper call. The reason is right here in the noun. A man in the office of the ministry holds something that does not belong to him — not his to withhold, not his to modify, not his to make interesting. The qualification lists of 1 Timothy 3 and Titus 1 read very differently once the deposit is in view: they are not describing an exceptional man but a trustworthy one, because trustworthiness is the only qualification a bailment actually requires.
It follows that the congregation’s confidence does not rest on the pastor. The Confessions are blunt about this — the Word and Sacraments are efficacious on account of Christ’s institution and command, not on account of the man’s holiness. A deposit is worth what the depositor put in it.
It is guarded by being taught. The most common misuse of this word runs toward defensiveness — the deposit as a thing to be protected from people, hedged with qualifications, kept out of untrained hands. Second Timothy 2:2 forecloses that reading in advance. Timothy is to guard the deposit by handing it to faithful people who will hand it further.
This is why Lutherans catechize, and why Luther wrote a Small Catechism for households rather than a manual for clergy. The plainest material the tradition produced was produced on purpose. A deposit that only experts can hold has already been diminished, whatever the intention. The pastoral instinct that wants to keep the faith safe by keeping it rare is, in the terms of Paul’s own metaphor, a failure of the trust.
The full treatment of parathēkē appears in Guard the Deposit, Session One, which continues with “Where People Get It Wrong,” “So What,” and “If You Want to Go Deeper.”
