each one

"each believer"

This is my rule in all the churches

Paul was teaching believers in all the churches to act in this manner.

Was anyone circumcised when he was called to believe

Paul was addressing the circumcised ones (the Jews). AT: “To the circumcised ones, when God called you to believe you had already been circumcised.” (See: rc://en/ta/man/translate/figs-rquestion)

Was anyone uncircumcised when he was called to faith

Paul was now addressing the uncircumcised ones. AT: "To the uncircumcised ones, when God called you to believe you were not circumcised." (See: rc://en/ta/man/translate/figs-rquestion)
