1-corinthians 7:18

Is any man called being circumcised? - Is any man who was formerly a Jew converted to Christianity?

Let him not become circumcised - Let him not endeavor to abolish the sign of the old covenant, which he bears in his flesh. The Greek words μη επισπασθω, let him not draw over, are evidently an elliptical expression: the word την ακροβυστιαν, the fore-skin, being understood; which, indeed, is added by the Armenian and the Itala, and several of the Latin fathers. It is a fact that it was possible by the assistance of art to do this; and Celsus himself prescribes the mode, De Medic. vii. 25. By frequent stretching, the circumcised skin could be again so drawn over, as to prevent the ancient sign of circumcision from appearing. Some in their zeal against Judaism endeavored to abolish this sign of it in their flesh: it is most evidently against this that the apostle speaks. Many false Jews made use of this practice, that they might pass through heathen countries unobserved; otherwise, in frequenting the baths they would have been detected.

Let him not be circumcised - Let no man who, being a Gentile, has been converted to the Christian faith, submit to circumcision as something necessary to his salvation.

Is any man called? - Does anyone become a Christian? See the note at 1 Corinthians 1:26.

Being circumcised - Being a native-born Jew, or having become a Jewish proselyte, and having submitted to the initiatory rite of the Jewish religion.

Let him not become uncircumcised - This could not be literally done. But the apostle refers here to certain efforts which were made to remove the marks of circumcision which were often attempted by those who were ashamed of having been circumcised. The practice is often alluded to by Jewish writers, and is described by them; compare 1 Mac. 1 Corinthians 1:15. It is not decorous or proper here to show how this was done. The process is described in Cels. de Med. 7:25; see Grotuns and Bloomfield.

Is any called in uncircumcision? - A Gentile, or one who had not been circumcised.

Let him not be circumcised - The Jewish rites are not binding, and are not to be enjoined on those who have been converted from the Gentiles; see the notes at Romans 2:27-30.
