This isn't my fight, but I want to at least provide some additional resource information that will give each of you the ability to cut each other up kindly with sharp knives rather than brutally bludgeon each other with tetanus-encrusted pitchforks (I know: the phrase doesn't really exactly apply here, especially if you can't free your mind from the stubborn thought of circumcision being performed with such pitchforks, but I loved the sound of it when it crept into my ridiculous mind):
The literal translation from Greek to English of Galatians 2:3 per the CLNT is, "But not even Titus, who is with me, being a Greek, is compelled to be circumcised."
We could just say, "Period," at the end of that sentence, because just by itself that sentence speaks volumes, but we could also do what is generally recommended, and that is to contemplate its context, which includes when it was written, about whom it was written, why it was written and, perhaps most importantly, to whom it was written (this last one becomes exponentially important when considering the context within the context as the context continues; keep that in mind also when reading certain books, like James and the Peters, which were written solely to the Messianic Jews and not to the Gentiles).
The Galatian verse in question is preceded immediately by Paul introducing the information that he had returned to Jerusalem for the first time in 14 years and that he took Barnabas and Titus (a Greek, no less). He did so in order to share a revelation (from You Know Whom) with the Apostles who were charged with evangelizing to the Jews (occasionally referred to as The Circumcision), as opposed to Paul's evangel to the Gentiles (just as frequently referred to as The Uncircumcision).
He follows 2:3 with all this through to the artificial end of Chapter 2: "Yet, it was because of the false brethren who were smuggled in, who came in by the way to spy out our freedom which we have in Christ Jesus, that they shall be enslaving us -- to whom, not even for an hour do we simulate by subjection, that the truth of the evangel should be continuing with you.
"Now from those reputed to be somewhat -- what kind they once were is of no consequence to me (God is not taking up the human aspect) -- for to me those of repute submitted nothing. But, on the contrary, perceiving that I have been entrusted with the evangel of the Uncircumcision, according as Peter of the Circumcision (for He Who operates in Peter for the apostleship of the Circumcision operates in me also for the nations), and, knowing the grace which is being given to me, James and Cephas and John, who are supposed to be pillars, give to me and Barnabas the right hand of fellowship, that we, indeed, are to be for the nations, yet they for the Circumcision -- only that we may be remembering the poor, which same thing I endeavor also to do.
"Now when Cephas came to Antioch, I withstood him to the face, for he was self-censured. For, before the coming of some from James, he ate together with those of the nations. Yet when they came, he shrank back, and severed himself , fearing those of the Circumcision. And the rest of the Jews also played the hypocrite with him, so that Barnabas also was led away with their hypocrisy. But when I perceived that they are not correct in their attitude toward the truth of the evangel, I said to Cephas in front of all, 'If you, being inherently a Jew, are living as the nations, and not as the Jews, how are you compelling the nations to be judaizing?'
"We, who by nature are Jews, and not sinners of the nations, having perceived that a man is not being justified by works of law, except alone through the faith of Christ Jesus, we also believe in Christ Jesus that we may be justified by the faith of Christ and not by works of law, seeing that by works of law shall no flesh at all be justified. Now if, while seeking to be justified in Christ, we ourselves also were found sinners is Christ, consequently, a dispenser of sin? May it not be coming to that! For if I am building again these things which I demolish, I am commending myself as a transgressor. For I, through law, died to law, that I should be living to God. With Christ have I been crucified, yet I am living; no longer I, but living in me is Christ. Now that which I am now living in flesh, I am living in faith that is of the Son of God, Who loves me, and gives Himself up for me. I am not repudiating the grace of God, for if righteousness is through law, consequently Christ died gratuitously."
Now I return you to your previously-scheduled slicing and dicing . . .
