God is one with one faith (Rom 3:30)

“God is one!

He will justify

The circumcised

On the ground

Of their faith,

And the uncircumcised

Through that same faith.”

εἴπερ εἷς ὁ Θεός, ὃς δικαιώσει περιτομὴν ἐκ πίστεως καὶ ἀκροβυστίαν διὰ τῆς πίστεως.

Paul explained that indeed God is one (εἴπερ εἷς ὁ Θεός).  He would justify (ὃς δικαιώσει) the circumcised (περιτομὴν) based on their faith (ἐκ πίστεως), and the uncircumcised (καὶ ἀκροβυστίαν) through that same faith (διὰ τῆς πίστεως).  Paul insisted that there was only one God.  This same God justified the people who were circumcised because of their faith, not their circumcision.  At the same time, he would justify those with foreskins or the uncircumcised through the same faith in Jesus.  One God, one justification, one faith, one Jesus, regardless of physical circumcision or not.  There was a unity of faith around one God.  Do you believe in one God like other people?
