All starts back when the Heavens were organized by Heavenly Father and Mother. They had spirit children in which their spirit bodies housed their intelligence that always existed. The greatest of spirit children was Jehovah. He obtained the status of lord God who is the Son of God. Father in Heaven brought us all together in a grand council to explain His Plan of Salvation that he himself had once maybe gone through. As Father in Heaven is a glorified perfect incorruptible man. His plan is to bring to past the immortality and eternal life of his spirit children. So, he organized His universe to be Father and God over to organize worlds upon end and populate them with his spirit children. Our earth was organized for one specific purpose. To send to the earth, lord Jehovah to atone for the sins that us humans would commit and prepare the way for the resurrection so that we too can become immortal and eternal and continue the plan for our eventual spirit children.
The most precious gift Father and Mother gave to us was free moral agency to choose for ourselves to follow Father in Heaven and lord Jehovah so that we can return after coming to this earth. Other of His children went to other planets to live on. What is unique about the souls who are here on our earth have the ability to actually kill their lord and Savior who would atone for their sins. There was a war in heaven. It was a disagreement between Jehovah and Lucifer. Lucifer wanted not to go through the trials and tribulations that this earth would present. He wanted to take us down here, control our every thought and action so that we would all return whether we wanted to or not. Father rejected Lucifer and a third of all of Father's children who wanted Lucifer's plan. Jehovah instructed Michael to form an army of righteous spirits who had accepted Father's plan and throw Lucifer and his minions out.
The stage was set and he sent Michael down to earth to take on the physical body of Adam. His spirit breathed life into Adam. He gave Eve to Adam as his wife. They had two choices that seemed at odds with each other. Don't eat of the fruit of knowledge of good and evil because they were in a state of innocence that could not be tempted. The other was to multiply and replenish the earth so that the rest of us could get down here and be tried and tested. Adam, pigheaded, didn't really stop and think about which is the greater good. Eve did and chose to start the process of bringing her and Adam's brothers and sister spirits to the earth.
While at the grand council, there were several chosen and accepted the call to be a mouthpiece for the Godhead of The Father, Son and Holy Ghost. The Godhead would reveal knowledge about the Godhead and what they wanted us to know so that we could choose to find our way back to Heaven. Specifically, the highest degree of Heaven (1Cor. 15. These persons would be called as apostles and prophets. Through them and only them would we know the proper plan of salvation to choose. Unfortunately, there were times that the world was so wicked that if there were prophets, no one was listening and keeping the commandments correctly as well a performing the ordinances of salvation and exaltation correctly. These times of total apostasy also made it impossible for people to know the plan to choose. So, our Godhead also made it possible for those people without opportunity to choose to choose after their life was over while in spirit prison. 1Peter 3:18-21. And, to also allow proxy baptism and other ordinances needed for exaltation. 1Cor.15:29.
So, it wasn't a repudiation of Jews or anyone else. Jews had free moral agency to choose for themselves. Some did but most at that time didn't. No one forced anyone to follow Jesus. Not God or Jesus or the Holy Ghost. Same today. No one is forcing you to follow the prophets of God of yesterday, today and the rest of the time before the 2nd Coming of the Lord. Now, the Catholic Church is guilty of forcing people to be converted or die or be expelled out of a country like Spain during the Inquisition as Pope Sixtus IV ordered Jews and Muslims killed. It's estimated between 32,000 and 300,000 were killed with the best estimate 125,000. There were other inquisitions before as well. Then, there is what happened to many indigenous people of the Americas by the Catholic Church as they slaughtered thousands if they would not convert. This is the work of Lucifer (Satan) to force people into converting.
In any event, the need for Jesus Christ is to help good people repent when they make mistakes and want to be forgiven by those they hurt as well as by the Lord and by Father. The Holy Ghost can help those who do not understand to understand if they repent and are teachable. The goal is to return to Heaven and after being judged to receive our incorruptible eternal resurrected bodies and go to the kingdom of heaven that we are assigned to, Celestial, Terrestrial, or Telestial (1Corinthians chapter 15). ONly through the resurrection of Jesus would this be possible.
