I disagree with your statement that
"Jesus was pointing to another group" instead of the
"synagogue of Satan"; meaning those who were not
"true Jews." Clearly there was persecution in the early church by the Jews to those who accepted Jesus as the Messiah as you can see from the following....
(Acts 5:27-42)
- They were "charged to not teach in His name" but Peter and the apostles answered "we must obey God rather than men."
- When they heard this they were enraged and wanted to kill them. (v 33)
- "...when they called in the apostles, they beat them and charged them not to speak in the name of Jesus, and let them go. Then they left the presence of the council, rejoicing that they were counted worthy to suffer dishonor for the name." (vs. 40-41)
(Acts 6-8:1)
- The arrest of Stephen..."because the (synagogue of the Freedmen) could not withstand the wisdom and the spirit with which he spoke." (vs. 9, 10)
- The apostle Stephen; the first martyrdom....."the elders and the scribes came upon [Stephen] and seized and brought him before the council, and set up false witnesses who said..." (vs. 12-13)
- The stoning of Stephen...."Now when they heard these things they were enraged, and they ground their teeth against him....But they cried out with a loud voice an stopped their ears and rushed together upon him. Then they cast him out of the city and stoned him; and the witnesses laid down their garments at the feet of a young man named Saul.....And Saul was consenting to his death."
(Gal 1:13)
At this time, Saul was passionately opposed to the teachings of the church and sought permission to go to Damascus and hunt down Christians wherever he could find them...."For you have heard of my former life in Judaism, how I persecuted the church of God violently and tried to destroy it,..."
Paul’s conversion was a bitter pill to the Jews of Damascus where he first began to preach this gospel. Paul, after his conversion, was subject to almost immediate threat to life and limb,... Paul was a Jew of high standing in his time, but somehow his standing afforded him no protection when he began to preach Christ crucified.
(Acts 9:23-25)
- His escape from the Jews..."When many days had passed, the Jews plotted to kill him, but their plot became known to Saul. They were watching the gates day and night to kill him; but his disciples took him by night and let him own over the wall lowering him in a basket."
Perhaps the most striking demonstration of the evolution of Jewish persecution is found in the treatment James, the brother of Jesus,
(Acts 12:1-5)
- The martyrdom of James and the imprisonment of Peter..."About that time Herod the king laid violent hands upon some who belonged to the church. He killed James the brother of John with the sword; and when he saw that it pleased the Jews, he proceeded to arrest Peter also...and put him in prison."
Shortly after James, the brother of Jesus was killed, the persecuted leadership of the church moved outside of Judea – to Pella in the early 60’s A.D. seeking safety from Jewish wrath. The Jews had persecuted the Christians in the hopes that they could protect their captive nation.
In addition to the reference to
"the Synagogue of Satan", in John 8:44, 47b where Jesus is speaking to the crowd in the temple court of the Gentiles, and of which the Jewish scribes and Pharisees were there also, he says to them...
"You are of your father the devil, and you want to carry out your father's desires..."
