Eph 2 seems to make a point of informing its readers that there is no difference between Jewish and Gentile readers.Anti something, for sure.
We Gentiles are... "Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God;" (Eph 2:19)
How can there be any more separation?
Gentiles, as well as Jews, have been freed from the Law.
"For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us;
15 Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace;" (Eph 2:14-15)
