No... not according to the Apostles, including Paul, an ex'Pharisee.
Read Acts of the Apostles
And Galatians.
The Apostles, [we'll call them early Christians, did not believe that all of the "mosaic" law was actually from Moses, but further, they clearly believed that circumcision was from the Mosaic law
Galatians 3:6-7
Galatians 3:10
Galatians 3:15
Galatians 3:18
Galatians 3:19
Which Paul called the 'added law'. [Added after the Covenant unto Abraham as Paul says.
When the jewish and common christian bibles were canonized later, they included the Abraham circumcision narrative, along with the narrative, that doesn't have that. Clearly the Apostles did not believe that part of what is in most modern bibles, as it would contradict much of Scripture, important Covenantal belief
Well seeing that you only go about cherry picking verses.
Have it ever occurred to you to read the whole chapter to find out for sure what the subject and article is about first.
But seeing you only pick out certain verses to try and support what your trying to say doesn't work.
As for Galatians 3:6-7. Here we find Abraham believed God, So God had Abraham circumcised himself in a show of faith in God.
So circumcision came from God to Abraham.
Seeing that you have no clue or idea what the works of the law are.
That are written down in the book of the law.
Maybe you should study to find out what the works of the law are, that are written down in the book of the law first.
As for Galatians 3:15--" Brethren, I speak after the manner of men; Though it be but a man's covenant, yet if it be confirmed, no man disannulleth, or addeth thereto"
Therefore not even Jesus could disannull the law of circumcision, so that means Jesus himself had to be circumcised himself.
Now as for Galatians 3:18-19--"
18--"For if the inheritance be of the law, it is no more of promise: but God gave it to Abraham by promise"
Therefore God gave to Abraham the law of circumcision.
19 Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator"
The law of circumcision was added because of transgressions,
Till the seed ( Jesus Christ) should come.
For Christ Jesus himself fulfilled the law of circumcision by being circumcised himself.
Maybe before you go about cherry picking verses you should try starting at the beginning of the chapter and find out what the subject and article is about first.
