Sanctification, eh?

¹⁴For the unbelieving husband is sanctified through his wife, and the unbelieving wife is sanctified through her believing husband; for otherwise your children are unclean, but now they are holy. (I Cor 7:14 NASB)

¹⁴For the Christian wife brings holiness to her marriage, and the Christian husband brings holiness to his marriage. Otherwise, your children would not have a godly influence, but now they are set apart for him. (I Cor 7:14 NLT)

I know that the point of the NLT is to translate the meaning of the Greek (while removing "churchy" jargon) and to make the Bible easy to read in English, however, I think that the word sanctified plays a very important role in this verse and shouldn't be translated otherwise in this case. Sanctification is a very specific term about what is going on in the verse. Sanctification is a common "churchy" word, and it is the process of making one holy. This is against the background of justification, which is your sins not being held against you in the eyes of God.
The verse is talking about being in a marriage with an unbelieving spouse. It is saying that if your unbelieving spouse is willing to live with you, you should not divorce him or her. When the NLT version says "brings holiness" it strikes a bad chord with me. In a lopsided way, it makes it seem that the verse could be talking about justification rather than sanctification, i.e. that God will consider your unbelieving spouse sinless if you choose to stay in the marriage with them. That's not what the verse says. If the verse is using the word sanctified, it is saying that your presence in the marriage will begin a process by which the actions of your spouse will become right (maybe you will convince him or her to go to church or he will see your life has changed and begin to question his own lifestyle). However, santification is not going to grant your husband justification. He can reject Christ, and according to the bible no matter how much influence you have upon your unbelieving spouse, it is only when they accept God's salvation that they will become justified.
Now after having this knowledge, you can reread the verse and clearly see what it was trying to say. It seems though that some new believer, who is inexperienced with the Bible and Christian culture would possibly misconstrue the meaning. Anyway, I'm going to get back to my Epistemology final. Peace out.
