Our conversation has nothing to do with the law as a way to be justified. Nothing. That issue....well....it's not even an issue. No argument being made in any way shape or form that the law somehow makes a person righteous. Messianic Christian's don't even breathe a whisper towards that argument.
No, no. It's a new thought in regard to 'we'. Obviously, the 'we' in verse 1 of chapter Romans 4 immediately following verse 31 of chapter 3 means those of natural descent from Abraham. It says that. But it's clear he's launching into a new thought, a new angle on the topic of justification by faith.
Back to verses 30 and 31....I showed you he's plainly saying both Jews and gentiles are justified together by faith. No change of thought between verse 30 and 31, so how is it that 'we' can only mean the 'Jewish' half of 'we'? He's just been speaking of them as one.
If 'we' in verse 31 only means Jews, then your doctrine has to explain why believing Jews are still 'under the law' (as your doctrine defines that), and gentiles aren't--even though Paul just got done saying both are equally justified by the same God through faith.
If your doctrine insists Jews are 'under the law', then suddenly pages of NT teaching about the 'end of the law' (and what that actually means--not what the church thinks it means) is now only applicable to the gentiles. Then we have an even bigger mess of playing the 'who does the law apply to?' game than we had before sorting out pages of pages of we's and who's and so on.
Circumcision was for any male servant born into the household of Abraham, or bought from a foreigner outside the household of Abraham:
"10 This is My covenant, which you shall keep, between Me and you and your descendants after you: every male among you shall be circumcised.11 And you shall be circumcised in the flesh of your foreskin, and it shall be the sign of the covenant between Me and you.12 And every male among you who is eight days old shall be circumcised throughout your generations, a servant who is born in the house or who is bought with money from any foreigner, who is not of your descendants.13 A servant who is born in your house or who is bought with your money shall surely be circumcised; thus shall My covenant be in your flesh for an everlasting covenant." (Genesis 17:10-13 NASB)
Your doctrine has to explain how this requirement for all servants regardless of descent to be in, and remain in, the covenant with Abraham was suddenly no longer an 'everlasting covenant' for any and all people in the covenant of Abraham when this same requirement got written down and included in the covenant of law. You can see the determining factor is if you are a servant of the covenant or not, not who your natural mother and father are.
Please don't try to explain your position.
Please, just answer the simple question.
Were uncircumcised gentiles obligated to uphold the law of Moses? [ By saying the law of Moses that means all the law of Moses ]
The question does not regard, if there were exceptions to those who were to be circumcised in the house of Abraham.
Abraham and his house were not under the law of Moses.

Just a simple yes or no.
I am trying to really understand where you are coming from.
