"Those in Christ".
The wall still existed, the ordinances still existed, and the enmity still existed long after Paul's letter to the Ephesians for those not in Christ.
However, for those "in Christ", there was no longer a difference between Jew and Gentile, there was no longer enmity between Jew and Gentile, there was no longer a partition wall between Jew and Gentile, and there was no longer any ordinances between Jew and Gentile.
For those Jews and Gentiles not "in Christ", there was still a wall that kept the Gentiles out of the Inner Court, there was still enmity between Jew and Gentile, and there was still ordinances between Jew and Gentile.
It's exactly what Paul was talking about.
There was only one Middle Wall of Partition that separated Jew from Gentile in all of mankind's history. It was impossible that Paul was referring to something else.
Lol - believe it or not,
much of your post there concords exactly with what the Actual Acts 9 Mid-Acts Position also concludes.
Baker had held that position
As had O'Hair; Stam; and Heath, et al.
And as does Sadler, and Jordan, and Kurth, and many other Pastor-Teachers within the actual Mid-Acts Position throughout the world.
I myself held that conclusion just before I found out there was even such a thing as the Acts 9 Position.
Lol, and I still recall running into some Acts 28ers (not Hybrids but straight out Acts 28ers) way back then - confused they were about this and other issues; and confused their Acts 28 Position has remained.
It is what it is...some - even without "the camp" get this one - and some don't.
Add to that the need of some to be so ugly towards anyone who points such things out, and you have one heck of an elitist, closed off individual and or individuals as a group; in such.
