in large part I would agree, Independent Baptist fellowships can be the best fellowships, but, there can be some erroneous ones as well. We don't consider any particular group to have flawless doctrine, and the measure or manner of worship is an individual issue, not a denominational issue.
Did the Lord also add Communion to circumcision?
Genesis 17:9-13
King James Version (KJV)
9 And God said unto Abraham, Thou shalt keep my covenant therefore, thou, and thy seed after thee in their generations.
10 This is my covenant, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised.
11 And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant betwixt me and you.
12 And he that is eight days old shall be circumcised among you, every man child in your generations, he that is born in the house, or bought with money of any stranger, which is not of thy seed.
13 He that is born in thy house, and he that is bought with thy money, must needs be circumcised: and my covenant shall be in your flesh for an everlasting covenant.
Do the offspring of Abraham need to add Communion to this everlasting Covenant?
I think Paul settled that issue fairly well.
And again, there is no command to Israel to shed her heritage, but...we do not confuse that with Eternal Redemption in Christ.
There is no Jew in Christ. There is no Gentile.
The Jew can celebrate Passover if he chooses, but, there is no impact to his salvation in Christ for either observing or not observing. That was not the case under Law...it was demanded.
So too with Communion, there is no command to partake in specified manner, only, "As oft as ye eat or drink."
Sure it did. "Jew" referred to the inhabitants of the land, and out of all tribes them that sought to worship God strengthened the Kingdom of Judah:
2 Chronicles 11:16-17
King James Version (KJV)
16 And after them out of all the tribes of Israel such as set their hearts to seek the Lord God of Israel came to Jerusalem, to sacrifice unto the Lord God of their fathers.
17 So they strengthened the kingdom of Judah, and made Rehoboam the son of Solomon strong, three years: for three years they walked in the way of David and Solomon.
In fact, in Christ's and the Apostles Day, they didn't even need to be living in Judah to be considered Jews:
Acts 2:5
King James Version (KJV)
5 And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven.
6 Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language.
7 And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilaeans?
8 And how hear we every man in our own tongue, wherein we were born?
9 Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia, and in Judaea, and Cappadocia, in Pontus, and Asia,
10 Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and strangers of Rome, Jews and proselytes,
11 Cretes and Arabians, we do hear them speak in our tongues the wonderful works of God.
Think about this, Robycop:
Matthew 2:2
King James Version (KJV)
2 Saying, Where is he that is born King of the Jews? for we have seen his star in the east, and are come to worship him.
Was Messiah promised to inhabitants of Judah only?
And that's it for me in this one.
God bless.
