If you had read the article I linked to, you would now know that yes, circumcision can become uncircumcision. It was done all of the time in ancient Rome. That is why it is written:
Is any man called being circumcised? let him not become uncircumcised. Is any called in uncircumcision? let him not be circumcised. 1 Corinthians 7:18
You may think you have defeated "the winds of doctrine", but it sounds like your ideas are breaking wind of doctrine.
RFTD, the reason I don't click on links, is because I took it upon myself to familiarize myself with the whole and express Word of God, and I found it to contain an unbroken chain of self revelation, which is what 2 Tim.2.15 says to "rightly divide the word of truth", so why in the world would I look further for information concerning the faith? And if I am right in what I have found and make known, then it is the Holy Spirit that wrote the Bible that you are insulting, and that is not a good idea...
Now as far as the ONE scripture you gave about circumcision; see also Eph.2.11 "wherefore remember, that ye being in times past Gentiles in the flesh, who are CALLED Uncircumcision by that which is CALLED the Circumscision in the flesh made by hands". That passage is concerning the Gentiles being made fellowcitizens with and built up into the household of God.
Rom.4.9-"--for we say that faith was reconed to Abraham for righteousness, how was it reconed? when he was in circumcision, or in uncircumcision? NOT in circumcision, but in UN circumcision. And he received the sign of the seal of the righteousness of the faith which he had yet being UNcircumcised; that he might be the father of all them that believe though they be NOT circumcised; that the righteousness might be imputed to them also. And the Father of circumcision to them who are not of the circumcision only, but who also walk in the steps of the faith of our Father Abraham, which he had being yet UNcircumcised".
Now it doesn't take a wizard to figure out that if we follow the faith steps of Abraham, we will be circumcised AS AN ACT OF FAITH, to have the sign of the seal of the promise in our flesh(if we are men), we will not be circumcised because we think the act will make us righteous, which is what some Jews thought and preached. What did Paul say about the Israelites? That they did not inherit the pomise because that sought it not by faith, it doesn't say the deed was wrong(Rom9.22).
