(KJV)1 Corinthians 7:14

For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband: else were your children unclean; but now are they holy.

Can a believer sanctify an unbeliever,for sanctification belongs to the Holy Spirit, is Paul here ascribing to men what belongs to God?

  • I think it's meant in the plain sense. The husband and wife keep each other holy (by not allowing each other to stray away from holy life). This no more violates the fact that God does it, andp rovides the grace to do so, than 1 Timothy 2:15 does. Or 1 Timothy 4:16 for that matter. Commented Jul 20, 2017 at 13:37
  • @SolaGratia Are you saying that the unbelieving spouse is thereby justified or converted?

  • Edified; sanctified. "Let no evil speech proceed from your mouth; but that which is good, to the edification of faith, that it may administer grace to the hearers." Ephesians 4:29. Commented Sep 16, 2017 at 11:57

Such a good question. It's especially interesting in light of 1 Corinthians 7:12

But to the rest speak I, not the Lord: If any brother hath a wife that believeth not, and she be pleased to dwell with him, let him not put her away.

1 Corinthians 7:14

For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband: else were your children unclean; but now are they holy.

It's not sanctified from sin. Which only God has the power to do. It is sanctified in holy declaration. The believer sanctifies the unbelieving spouse or declares them holy.

Exodus 19:22

And let the priests also, which come near to the LORD, sanctify themselves, lest the LORD break forth upon them.

Leviticus 11:44

For I am the LORD your God: ye shall therefore sanctify yourselves, and ye shall be holy; for I am holy: neither shall ye defile yourselves with any manner of creeping thing that creepeth upon the earth.

You can sanctify that which you do by dedicating it to God i.e. by dedicating your work unto God, you sanctify it. By dedicating your marriage or spouse unto God, you sanctify it.


The Greek word here is ἁγιάζω, which the KJV translates as "sanctify" or "make holy", but more modern versions (e.g. RSV) sometimes translate as "consecrate". It is in this sense, for example, that the word is used sometimes in the Septuagint, such as:

Numbers 6:11–12 LXX

καὶ ποιήσει ὁ ἱερεὺς μίαν περὶ ἁμαρτίας καὶ μίαν εἰς ὁλοκαύτωμα, καὶ ἐξιλάσεται περὶ αὐτοῦ ὁ ἱερεὺς περὶ ὧν ἥμαρτεν περὶ τῆς ψυχῆς καὶ ἁγιάσει τὴν κεφαλὴν αὐτοῦ ἐν ἐκείνῃ τῇ ἡμέρᾳ, ἧ ἡγιάσθη κυρίῳ τὰς ἡμέρας τῆς εὐχῆς, καὶ προσάξει ἀμνὸν ἐνιαύσιον εἰς πλημμέλειαν, καὶ αἱ ἡμέραι αἱ πρότεραι ἄλογοι ἔσονται, ὅτι ἐμιάνθη κεφαλὴ εὐχῆς αὐτοῦ.

And the priest shall offer one for a sin-offering; and the other for a whole-burnt-offering; and the priest shall make atonement for him in the things wherein he sinned respecting the dead body, and he shall sanctify his head in that day, in which he was consecrated to the Lord, all the days of his vow; and he shall bring a lamb of a year old for a trespass-offering; and the former days shall not be reckoned, because the head of his vow was polluted.1

I believe this latter sense is the way we are to understand 1 Corinthians 7:14. This is also the sense that it seems to have been understood in antiquity. John Chrysostom writes, for example,

"The unbelieving husband is sanctified through his wife, and the unbelieving wife is sanctified through her husband." Yet earlier he said, "Do you not know that he who joins himself to a prostitute becomes one body with her?"2 We might then conclude that a woman joined to an unbelieving idolater becomes one body with him. Is there a contradiction here? No, because although they become one body, the woman is not defiled, since the purity of her faith is stronger than the impurity of his unbelief. Likewise the purity of a believing husband is stronger than the impurity of a believing wife ... There is hope that the spouse who is perishing through his unbelief might be saved through marriage to a believer.3

The historical context is also relevant, I think. At the time that Paul was writing, Christians were a very small minority. Cases abounded where one or other of a married pagan couple would accept Christ before the other. Paul is addressing a practical marital issue here, in guiding spouses how they are to continue to relate to their still unbelieving spouse. The advice given here shows that Paul felt it was better for a couple to remain married, with the believing spouse living in the hope of his or her spouse eventually converting, than for the believer to simply abandon the unbelieving spouse.

1 Brenton English translation
2 1 Corinthians 6:16
3 Homily XIX on 1 Corinthians, tr. from Greek in St. John Chrysostom: On Marriage and Family, p.31


In verse 12 of this passage, Paul says [quoted from NASB]

But to the rest I say, not the Lord, that if any brother has a wife who is an unbeliever...

In light of this, I believe there may be a cultural element to verse 14, especially as pertains to the children

...for otherwise your children are unclean, but now they are holy.

We know from Psalm 49:7-8

No man can by any means redeem his brother or give to God a ransom for him - for the redemption of his soul is costly, and he should cease trying forever.


The point of the passage is that for the sake of the believing spouse's children the unbelieving spouse is divinely consecrated to the holy work of parenting them. Of all the people on earth the parent is uniquely divinely dedicated to their well being. The care of a believer's children is a holy work and God regards the unbelieving parent's role as he does that of a priest for the priest might just prepare show bread or kill animals but the unbelieving parent is caring for children that are, in a limited sense, God's grandchildren.

A father may not approve of his daughter's involvement with an unbeliever but if she marries and has children by the unbeliever then that man becomes the most important man in the world to that father. He will do his best to support the couple, perhaps bringing him into the family business and granting him inheritance.

The same would be true of an unbelieving wife.

This does not guarantee the unbelieving spouse's ultimate justification but while they are parent of a believer's child they are in God's view consecrated to a holy work and in that regard are esteemed as holy, dedicated servants of God.


I would translate 1 Corinthians 7:14 like this:

For the unbelieving husband has been hallowed by the wife, and the unbelieving wife has been hallowed by the brother. It being otherwise so, your children are unholy. But, as it now stands, are holy.


enter image description here

The Greek word ἡγίασται(1), given here as "hallowed", means "to separate from profane things and dedicate to God".

A believer is hallowed by the Holy Spirit, and thus set apart (taken out of the world) for the holy calling of advertising the presence and goodness of God. In the same way the unbelieving wife/husband is set apart (taken out of the world) by the believing husband/wife for the holy calling of building a godly family, i.e. one that testifies to the presence and goodness of God.

Thinking of it any other way, says Paul, would mean that the offspring of such unions could only be unholy.

This notion is precisely why festivals that used to be pagan, e.g. Easter and Yuletide (Christmas), became legitimate holy festivals, since they were co-opted and set apart from their profane origins, for the purpose of advertising the presence and goodness of God.
