1 Corinthians 7:18–20
18 Was anyone called while circumcised? Let him not become uncircumcised. Was anyone called while uncircumcised? Let him not be circumcised.
19 Circumcision is nothing and uncircumcision is nothing, but keeping the commandments of God is what matters.
20 Let each one remain in the same calling in which he was called.
Paul’s writing is challenging to understand in this chapter. The context has been husbands and wives. Once a husband or wife is saved, how shall they then live? Was anyone called, can we assume that Paul means called into the faith? By the word called, he probably means invited to believe.
Circumcised and uncircumcised refers to Jew and Gentile. To make it known a person was not of Israel; he was called the uncircumcision, (Jew and Gentile are English Bible terms).
This whole idea of circumcision and uncircumcision seems to be put in context in verse 19 when he says, it is nothing.
Is Paul saying that the commandments of God are not something that the church is under? It appears he is. Paul spent a year and a half with this church, teaching them. Indeed, he had taught them that believers are not under the Law. Now he is reminding them of that fact: The commandments were for the nation of Israel. The church is free from the ordinances written in the commandments.
Let each one remain in the same calling, stay in the relationship you are in once you believe, even if the other does not believe.
