Just so you know what I believe about circumcision (I believe it is consistent with Reformed Baptist CT).
I am only mentioning this, just in case you may not be aware of what I believe on the subject.

Physical circumcision and "circumcision of the heart" are related only in the aspect that circumcision being a picture (type) of circumcision of the heart.
I believe that is basically what Romans 22:25-29 is saying.
The physical aspect of circumcision is found in Romans 3:1-…, “…unto them were committed the oracles of God.” This is something that only physical Israel were entrusted with.
This aspect did not depend on if they were circumcised of the heart or not.
True Israel on the other hand are as Paul puts it (Romans 9:8) “That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.” This of course, even in the Old Testament wasn’t always something that pertained only to physical Israel.
Of course now the Church is the true Israel of God, all who are in Christ.
