Seeing it is one God
God is one in nature and essence, though there are three persons in the Godhead, Father, Son, and Holy Ghost; whence it appears, that he that is the God of the Jews, is also the God of the Gentiles, or there would be more gods than one; and that these are justified in one and the same manner, or God must be divided; for God, as he is one in nature, so he is one in will, in his promises, and in the methods of his grace:
which shall justify the circumcision by faith, and uncircumcision
through faith.
The objects of justification are "the circumcision", the circumcised Jews, and "the uncircumcision", the uncircumcised Gentiles; the circumcision of the one does not forward, and the uncircumcision of the other does not hinder, nor neither of them effect the grace of justification: the justifier of them is one and the same, who is God; and the matter of their justification is the same, which is the righteousness of Christ; and the manner of it, or the means of their comfortable apprehension of it, is the same; for those phrases, "by faith", and "through faith", mean one and the same thing; see ( Philippians 3:9 ) .
