CIRCUMCISION REFERS TO A JEW AND UNCIRCUMCISION REFERS TO A NON-JEW

1 Corinthians 7:18 Is any man called being circumcised [A Jew]? let him not become uncircumcised [act like the nations]. Is any called in uncircumcision [non-Jew]? let him not be circumcised [follow the customs of the Jews].

1 Corinthians 7:19 Circumcision [being born Jewish] is nothing and uncircumcision [being born a non-Jew] is nothing but the keeping of the commandments of God.
