The Council of Jerusalem (49 A.D.) eliminated the act of circumcision as any type of outward sign or covenant to be called a child of Yahweh. It was established as many adult male converts were coming into the church.....but many more would not.... because of the circumcision requirement by the Church [Acts 15:1-5].
The Jerusalem Church had been sending out circumcision patrols throughout Asia Minor....telling adult converts they must be circumcised to belong to the new church [Galatians 2:12]. This was a source of great dispute by Paul and Barnabas and infuriated them [Acts 15:2]...and was the impetus for the Jerusalem Council.
After Peter, Barnabas and Paul finished their plea to the council regarding circumcision.....James, the leader of the Church relented and issued this decree:
[Acts 15:19-21] 19Wherefore my sentence is, that we trouble not them, which from among the Gentiles are turned to God: 20But that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood. 21For Moses of old time hath in every city them that preach him, being read in the synagogues every sabbath day.
Notice that no such pronouncement was given regarding the Sabbath....and in fact, James even implies that these same adult, male, Gentile converts will continue to learn about "Torah" by attending Sabbath services....weekly.
Acts 15 eliminated circumcision for adult, male converts but nothing was said regarding the Sabbath. This fact stands out because..... if the Church had not yet done so....this would have been an excellent time to say, "Hey boys.....we'll see you at Sunday morning services!"
They hadn't....and they didn't!
Oh???
Acts 15
24 We have heard that some went out from us without our authorization and disturbed you, troubling your minds by what they said. 25 So we all agreed to choose some men and send them to you with our dear friends Barnabas and Paul— 26 men who have risked their lives for the name of our Lord Jesus Christ. 27 Therefore we are sending Judas and Silas to confirm by word of mouth what we are writing. 28 It seemed good to the Holy Spirit and to us not to burden you with anything beyond the following requirements: 29 You are to abstain from food sacrificed to idols, from blood, from the meat of strangled animals and from sexual immorality. You will do well to avoid these things.
Farewell.
