Acts 8:1 And Saul was consenting unto his death. And at that time there was a great persecution against the church which was at Jerusalem; and they were all scattered abroad throughout the regions of Judaea and Samaria, except the apostles.
James 1:1 James, a servant of God and of the Lord Jesus Christ, to the twelve tribes which are scattered abroad, greeting. 1:2 My brethren, count it all joy when ye fall into divers temptations; 1:3 Knowing this, that the trying of your faith worketh patience. 1:4 But let patience have her perfect work, that ye may be perfect and entire, wanting nothing.
That was then.
Followed by a change in that AFTER Paul was saved...
Acts 9:27 But Barnabas took him, and brought him to the apostles, and declared unto them how he had seen the Lord in the way, and that he had spoken to him, and how he had preached boldly at Damascus in the name of Jesus. 9:28 And he was with them coming in and going out at Jerusalem. 9:29 And he spake boldly in the name of the Lord Jesus, and disputed against the Grecians: but they went about to slay him. 9:30 Which when the brethren knew, they brought him down to Caesarea, and sent him forth to Tarsus. 9:31 Then had the churches rest throughout all Judaea and Galilee and Samaria, and were edified; and walking in the fear of the Lord, and in the comfort of the Holy Ghost, were multiplied.
So that by the time of the following; their persecution by their own (some within the Sanhedrin) was largely over with, and now their chief persecutor: Paul, was the one ever being persecuted (by some within The Sanhedrin).
Acts 21:18 And the day following Paul went in with us unto James; and all the elders were present. 21:19 And when he had saluted them, he declared particularly what things God had wrought among the Gentiles by his ministry. 21:20 And when they heard it, they glorified the Lord, and said unto him, Thou seest, brother, how many thousands of Jews there are which believe; and they are all zealous of the law: 21:21 And they are informed of thee, that thou teachest all the Jews which are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children, neither to walk after the customs. 21:22 What is it therefore? the multitude must needs come together: for they will hear that thou art come. 21:23 Do therefore this that we say to thee: We have four men which have a vow on them; 21:24 Them take, and purify thyself with them, and be at charges with them, that they may shave their heads: and all may know that those things, whereof they were informed concerning thee, are nothing; but that thou thyself also walkest orderly, and keepest the law. 21:25 As touching the Gentiles which believe, we have written and concluded that they observe no such thing, save only that they keep themselves from things offered to idols, and from blood, and from strangled, and from fornication. 21:26 Then Paul took the men, and the next day purifying himself with them entered into the temple, to signify the accomplishment of the days of purification, until that an offering should be offered for every one of them. 21:27 And when the seven days were almost ended, the Jews which were of Asia, when they saw him in the temple, stirred up all the people, and laid hands on him, 21:28 Crying out, Men of Israel, help: This is the man, that teacheth all men every where against the people, and the law, and this place: and further brought Greeks also into the temple, and hath polluted this holy place. 21:29 (For they had seen before with him in the city Trophimus an Ephesian, whom they supposed that Paul had brought into the temple.) 21:30 And all the city was moved, and the people ran together: and they took Paul, and drew him out of the temple: and forthwith the doors were shut. 21:31 And as they went about to kill him, tidings came unto the chief captain of the band, that all Jerusalem was in an uproar. 21:32 Who immediately took soldiers and centurions, and ran down unto them: and when they saw the chief captain and the soldiers, they left beating of Paul.
Admittedly, that does not fit the Preterist Scripture twisting (in their ignorance of the actual cohesiveness of these things) that you long ago...fell prey to.
The fact that said persecution of James' readers temporarily fell by the wayside with the salvation of what appears to have been the loss of The Sanhedrin's chief "zealot" against them, after he himself was saved, goes right passed you long since books based wisdom of men.
Acts 26:8 Why should it be thought a thing incredible with you, that God should raise the dead? 26:9 I verily thought with myself, that I ought to do many things contrary to the name of Jesus of Nazareth. 26:10 Which thing I also did in Jerusalem: and many of the saints did I shut up in prison, having received authority from the chief priests; and when they were put to death, I gave my voice against them. 26:11 And I punished them oft in every synagogue, and compelled them to blaspheme; and being exceedingly mad against them, I persecuted them even unto strange cities. 26:12 Whereupon as I went to Damascus with authority and commission from the chief priests, 26:13 At midday, O king, I saw in the way a light from heaven, above the brightness of the sun, shining round about me and them which journeyed with me. 26:14 And when we were all fallen to the earth, I heard a voice speaking unto me, and saying in the Hebrew tongue, Saul, Saul, why persecutest thou me? it is hard for thee to kick against the pricks. 26:15 And I said, Who art thou, Lord? And he said, I am Jesus whom thou persecutest. 26:16 But rise, and stand upon thy feet: for I have appeared unto thee for this purpose, to make thee a minister and a witness both of these things which thou hast seen, and of those things in the which I will appear unto thee; 26:17 Delivering thee from the people, and from the Gentiles, unto whom now I send thee, 26:18 To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me. 26:19 Whereupon, O king Agrippa, I was not disobedient unto the heavenly vision: 26:20 But shewed first unto them of Damascus, and at Jerusalem, and throughout all the coasts of Judaea, and then to the Gentiles, that they should repent and turn to God, and do works meet for repentance. 26:21 For these causes the Jews caught me in the temple, and went about to kill me. 26:22 Having therefore obtained help of God, I continue unto this day, witnessing both to small and great, saying none other things than those which the prophets and Moses did say should come: 26:23 That Christ should suffer, and that he should be the first that should rise from the dead, and should shew light unto the people, and to the Gentiles.
