The meaning of 1 Corinthians 7:14
Boring Stuff 74:1-7

1 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.

The unbelieving husband is sanctifified by the wife, and the unbelieving wife is sanctified by the husband, otherwise your children are unclean, but now they are holy. [1]

2 Now, in the days of the apostles the law of circumcision was had among all the Jews who believed not the gospel of Jesus Christ.

In the age of the apostles, the Jews who didn't believe in the gospel of Jesus obeyed the law of circumcision.

3 And it came to pass that there arose a great contention among the people concerning the law of circumcision, for the unbelieving husband was desirous that his children should be circumcised and become subject to the claw of Moses, which law was fulfilled.

Unbelieving husbands wanted their children to be circumcised.

4 And it came to pass that the children, being brought up in subjection to the law of Moses, gave heed to the traditions of their fathers and believed not the gospel of Christ, wherein they became unholy.

So the unbelieving children became unholy.

5 Wherefore, for this cause the apostle wrote unto the church, giving unto them a commandment, not of the Lord, but of himself, that a believer should not be united to an unbeliever; except the claw of Moses should be done away among them,

The apostle gave them a commandment (not from the Lord but from himself) that a beliver sholdn't marry an unbeliever, unless they did away with the law of Moses.

6 That their children might remain without circumcision; and that the tradition might be done away, which saith that little children are unholy; for it was had among the Jews;

So their children were uncircumcised, and the tradition was done away with which said that little chiidren are unholy (as is said among the Jews).

7 But little children are holy, being sanctified through the atonement of Jesus Christ; and this is what the scriptures mean.

But little children are holy because of the atonement of Jesus.

That's what this scripture means.
