How did the Crucifixion affect Roman-Parthian relations?

The anticipation of the Messiah changed both the Roman and Parthian Empires, the crucifixion more so. Parthia was a confederation of tribes that Roman legions tried to conquer. Parthia was the Super-Power of the East, a deadly rival of Rome's military autocracy.

Parthia trounced mass invasions of Roman legions several times. In 55 BCE Parthian King Orodes slaughtered 40,000 legionnaires under Consul Crassus. In 40 Parthia invaded the Holy Land and deposed the Roman-designated high priest. Parthia soundly defeated Mark Antony in 37 BCE. In 34 BCE Julius Caesar was assassinated mysteriously before his planned invasion of Parthia.

The two empires made peace in 22 BCE under Augustus and Phraates IV (=Arsaces XXII). Why?

Parthia was run by the Arsacid dynasty (250 BCE to 225 CE). Its rulers were composed of Israelite and Jewish exiles (Sons and rulers rosh of ISaac). Secular histories say they were formerly slaves and called themselves Exiles (Parthi in Scythian or Hebrew Galut = Gauls, Galatians, Kelts). They wanted to rebuild the Temple in preparation of the Messiah, dated according to Daniel’s prophecies. (Daniel was member of the Persian Magi, the priestly class of scientists and prophets).

The reconstructed Temple became the most important and biggest construction site of the time (one million man-years work). Vast riches were received from across both empires and around the world (Josephus).
Jesus was identified by genealogy and miracles as the Son of David through Joseph. Mariam (Mary) was of pure Aaronic descent. Jesus was not an itinerant preacher, Protestant style! Pilate acknowledged him as King of the Jews. Pilate recognised Jesus as having a higher rank that he had, as merely a governor of Rome but not a royal. The high priests called Pilate Lord, (Kurios) but Jesus did not.
The resurrection was a shock to both the high-priestly ruling class and the Romans. Ample evidence existed it took place with many Roman witnesses, including Pilate. Based on diplomatic reports of Pilate, Emperor Tiberius acknowledged that Jesus Christ was a god. The Senate, however, refused to ratify this. Tiberius decreed however that anyone who persecuted the Nazarenes (his followers) would be put to death (Tertullian etc).
When Tiberius died in 37 CE (at the hands of Gaius Caligula), Caligula became emperor. He saw that the resurrection undermined the whole Roman/Greek pantheon. Roman gods had to be authorised by the Senate. But here was a Jewish king resurrected and recognised as a god by Tiberius! Caligula, drawn by Egyptian paganism, wanted to be deified as God of this world. In that way he would, he thought, outclass Christ. He planned first to raise a mammoth idol of himself in the Temple of Jerusalem. Why? Because Christ had prophesied that the Abomination of Desolation would stand in the Temple before the end of the Age. This was also prophesied by Daniel (Matt 24:15). Caligula wanted to prove Christ wrong and that he was all-powerful and more god than Jesus. He failed.
The later emperors like Claudius were at first more cautious with the Christian threat, but then introduced a vicious campaign of anti-Semitism, trying to provoke a Jewish revolt. Wars broke out from Britain to Parthia.
James the brother of Jesus was Sagan and Priest of Warfare in the Temple and advised passive resistance. He was killed in the Temple around 62 CE and the high-priestly class then refused to make offerings to the Roman emperor in the Temple. This led to the war with Rome.
it also created a dilemma for Parthia (which was not a military dictatorship like Rome). Suppressing a revolt in Judea did not violate the peace treaty. Titus went further. He destroyed the Temple. He said that that way he would put an end to both Judaism and Christianity (Sacred History of Sulpicius Severus) quoted on NazareneProject site. Titus raised a pagan pillar to his father on or near where the Temple had been.
The Parthian empire lasted nearly two centuries further but on a war-like footing. The Parthian Peace based on the Temple and its Messiah had lasted longer than almost any other in history. The Roman pantheon was destroyed by the resurrection. Rome reverted to Sun worship and foreign cults. The gods like Jupiter, Mars, Minerva became a laughing stock. Rome tried syncretism — trying to combine their paganism with the facts of the resurrection and resurgent Christianity.

Review of PBS film: 'Last Days of Jesus"

The academics should be commended in trying to bring some contemporary Roman background into the gospel history. The PBS film on the "Last days of Jesus" can be found on You Tube at https://www.youtube.com/watch?v=gLStDEBPCfo&t=3848s They did not however begin to address the major problem of Jerusalem politics: the Temple. This had been rebuilt with the aid of Parthia, the Israelite-run Super-State rival of Rome -- with whom Tiberius had tried to make and keep peace.  Vast populations of the Diaspora in Europe had also contributed in anticipation of the coming Messiah.

1. Sejanus was a key figure, a fervent anti-Semite. He like other Romans hated the fact that the Jews and the Temple were not subsumed in the Roman central control of the pantheon and the College of Pontiffs. Historical facts of the gospels in a Hebrew context make perfect sense. The scholars have, however, indirectly pointed to problems arising from the "Easter" week tradition of 4th century Constantine's imperial church. That tradition arose once he had eliminated all Jewish Christians. (The latter knew about the Passover dates, Davidic kingship and true high priesthood.) It is not honest scholarship if "scholars" re-write the gospels at their whim because of these conflicts or ignorance of first century Judaism. If the gospels are read as Jewish-Christian or Nazarene documents, many of the supposed "difficulties"disappear.

2. However, the program's theory of stretching a day to six months (including a half-year stay of Jesus in prison) does not hold water. The chronology is forced out of shape. The Crucifixion/ Resurrection occurred in 30 CE (verifiable by the Hebrew calendar). Sejanus was at his peak of power. Major facts left out: Christ cleansed the Temple at least two times. He cleansed it at the start of his mission. What is remarkable is that he had no resistance from the armed Temple guard, nor did the Roman legions intervene. What did he cleanse? The area was the periphery of the square Temple complex which was a furlong in length. The merchants' area may well have covered half a mile. Furthermore Mark 11 says he let no one carry vessels through the Temple. Alone? The gospels say the Temple guards ('the boys') cried Hosanna! He was in charge of the Temple guard! He had authority as an Aaronic priest because his mother was a daughter of Aaron, a direct descendant. So was John the Baptist via Elizabeth (Elisheva). John is called a high priest in the Hebrew Josephus. The next morning the high priests like Caiaphas, Annas came peaceably like kittens to converse with Jesus. Their question was about authority. Jesus had this. They didn't.
3. What is the picture with the correct chronology of 30 CE? Tertullian and others confirm that Pilate wrote dispatches to emperor Tiberius that the Resurrection actually happened and was eye-witnessed by the masses. It was undeniable. hence Tiberius acclaimed Jesus as god. The Senate (which was then led along by Sejanus) objected. They dug out an old law saying the Senate had to approve in the naming of gods! Tertullian mocks them, saying the poor gods, they would have to pray to the Senators that they should be recognized! Tiberius replied that anyone who attacked the Jews would be killed. It was at this stage that the plot of Sejanus fell apart. Sejanus was exposed and executed in autumn 31 CE. Later secular writings to the emperors indicate that Christ's divinity -- via the Resurrection -- was not challenged. The proof was irrefutable. Jesus was not a Protestant-style "preacher". He was a Teacher, a Temple Teacher. He taught in the Temple -- which is why the Davidic and Aaronic genealogies are in the gospels. They provide the proof of his authority. (It was forbidden to enter the Temple with long hair! ) The high priests call Pilate "Lord" as representative of Rome. But Jesus didn't. Why wasn't this a crime? He outranked Pilate. Pilate calls him King of the Jews and says he is innocent of any crime. Why? Because the Temple was considered a separate City-State with its own rules and armed priests. This was recognized in the treaty Julius Caesar made with the Maccabees.
If the academics would have stuck to the facts and proper dates, and avoided pet theories, they would have had a clearer explanation of many if not all of the problems they were seeking to elucidate. They would have also found that for the Romans, for Tiberius and for Pilate and Sejanus, 30 CE and 31 CE were not the 'Last Days of Jesus'!

Pilate, Sejanus and the Resurrection of Christ

1. Jesus Christ (=the anointed king) was crucified on a tree in 30 CE.
It was not his 'last days' as he was resurrected to the general knowledge of all at Jerusalem. Forty days later he ascended in full public view from the Mount of Olives -- this would have included all the priests and people in the Temple and all the soldiers in the Roman Fort, the Praesidium (up to 10,000 legionnaires and ancilliaries) plus all the pilgrim crowds.
The second-century Christian lawyer,Tertullian, recorded that Pilate wrote dispatches to the emperor Tiberius about this to give the official version as everyone around the empire already knew about it.
Pilate was extremely anti-Semitic and had probably been placed there by the violently anti-Semitic Sejanus to stir up trouble. Yet he affirmed the eye witness accounts.
Sejanus had been plotting for years to overthrow Tiberius who had retired from official duties for sex games in Capri.Sejanus, his Praetrorian Guard chief, was de facto emperor. He became so powerful and manipulative that many Romans worshipped in a cult. He was a smooth operator with the Senators who were vital should he succeed in his plan.No one could put their name forward as a Consul without his favour. Sejanus became a Consul with Tiberius -even though he was not ranked as a Senator. With this Sejanus hoped that he would just eliminate Tiberius and everyone would presume he should be emperor although he was not of any imperial family. He was overcome with egotism -- and hate of Jews.
Sejanus, possible statue
2. The Resurrection threw this long-gestating plan into a spin. Tiberius, say Tertullian and other early writers, acknowledged that Jesus Christ was god. Sejanus and the Senate tried to stop this as it would mean ruin for their centralized control after a coup d'État.
The Senate pulled out an old law that said that only the gods approved of by the Senate were gods! This was clearly nonsense as a royal and priestly Jew had been resurrected to everyone's knowledge.
Tertullian mocks this pagan foolishness, saying the poor gods would have to pray to the Senators so they could be recongized as gods!! Furthermore many saints as Matthew says rose from their graves at this time. The archaeological and written proof of this are in the book.
3. Sejanus's reaction later in 30 CE and early 31 was to try to exterminate all Jews. That's what Philo and others say. Exterminating all believers would mean that Rome could turn back to ribald, old-time paganism. Instead his treasonous plot was revealed to Tiberius (who was not so anti-Semitic and more interested in maintaing imperial peace with Parthia). The old emperor did some some careful investigation and deft political footwork. Sejanus was "dethroned" and skewered.
Tiberius then proclaimed that anyone persecuting Christians (or Nazarenes as they were then called) would be killed. The ekklesia had seven years of peace.
4. Sejanus, who had been head of the Pretorian guard, was replaced by Macro. Gaius Caligula colluded with Macro and killed Tiberius. Caligula's way of dealing with the Nazarenes and the Jews/ Israelites/ Parthians/ Kelts was to provoke the Jews into a war of extermination, while trying to hold off the Parthian Super-Power enemy so they would not come to defend Jerusalem and the Jews.
Caligula already had his statue set up in all synagogues around the Empire. Jews suffered at this idolatry. Caligula wanted to go to Egypt where he would be made a god, 'as Egyptians knew better than Romans how to make a man divine'.
Philo Judaeus of Alexandria in Egypt made the cutting but careful remark: "to change God into a man is more easily done than to change a man into God.'
The Roman Supreme Commander in the East stationed in Syria, Petronius, prepared for war with Parthia. It seemed inevitable. Why? Caligula had ordered him first to set up a giant gold statue of Caligula as Jupiter and place it in the Jerusalem Temple. After that Caligula said he would come and set up his imperial Roman headquarters in the Temple.
We can easily guess why. Because Christ had said that 'an abomination of desolation' would sit and rule in the Temple as God. Caligula wanted to prove Christ wrong.
This act would have meant World War as Jews and Parthians and the Israelite Diaspora would attack and defend their most beautiful and precious City and the holy Temple to which they had all contributed in rebuilding for half a century since the time of the Parthian peace treaty.
Both Philo and Josephus say that the Israelite Diaspora were in number the greatest people on earth, though scattered in several countries and islands.
5. World War did not come. Caligula failed to conquer Britain, where Christianity took hold and was evangelizing the Continent. The "Triad of Lazarus" showed how false his divinity claim was. Caligula was assassinated in a back alley in Rome as he prepared to leave for Egypt. Dogs drank his blood. These dramatic events only added to the number of believers around the world.

Was there a "lost century" of Christian history after 70 CE?

Does the "Lost Century" of Church history exist?
NO
This so-called missing century goes from just before the destruction of the Temple in 70 to 150 or 170 CE. What happened to the Church?
1. The first mistake is to use the term 'church' . It is not in the Bible! Early believers were called an ekklesia. As a Greek term, it means congregation, an official assembly. The later "Church" is a pagan term, reflecting pagan organization and pagan structure. The ekklesia translates the Hebrew qahal or tribal or national Congregation or assembly. It is a very specific term. The qahal were Israelites and composed the Congregation of Israel that met in the Temple for specific rituals.
Ever wonder why the book of Acts speaks of 120 'names' witnessing the Ascension of Christ? Names means that they were nominated. They were ambassadors from the twelve scattered tribes of Israel. Jesus visited all the tribal capital cities -- as is clear from the NT. Shechem was Joseph and other patriarchs were and are buried. 120 = 12 x 10. They came from Parthia -- Rome's superpower rival to the East -- and from wherever the Israelites were scattered.
2. Part of the confusion about the early ekklesia in the period 50 to 150 is due to the popular history sources people use. Many books quote Gibbon who was a skeptic. He discounts the Resurrection as a real event, ignores important witnesses, and downplays Philo and Josephus. They record that Sejanus, who had practically the power of emperor while Tiberius was semi-retired in Capri, acted much like Hitler or Islamic State against the Jews. He led many of the senate who wanted to exterminate all the Jews. Why? This was in the early 30s, even before Caligula took power. Sejanus had Tiberius's son Drusus poisoned and wanted to take over the Empire. Tiberius was alerted and had him removed and executed. Gibbon omits these major events of the first century and then talks about a 'thick mist'! That's hardly surprising: remove some facts and claim a mystery.

Gaius Caligula Caesar

What was going on? The Resurrection threatened Rome. In his chapter 15 he hardly deals with Caligula -- except calling him mad. It is hardly a coincidence that Gaius Caligula emperor 37 to 41 CE decided to call himself 'God' and Jupiter. Rome balked at this, so Caligula said he would go to Egypt who were experts in making emperors gods. 

Then he said he would set up his headquarters in the Temple in Jerusalem. Why the Temple? He would challenged Almighty God and all the prophecies of Christ about the Abomination of Desolation! 

Read Tertullian and it is easy to understand. He lived in a time a century later when he was freer to tell the story without being attacked.

He said that in 30 CE the emperor Tiberius agreed to call Jesus 'God' because he was convinced by the reports from Pilate about the Resurrection. Why did not the whole Empire proclaim the resurrected Jesus as God? Tertullian says that the Senate refused. Why? Because they knew a resurrected Christ, officially recognized by the State, would undermine the whole pantheon of Rome -- Jupiter, Venus, Mars, Minerva etc. They said the Senate (at odds with Tiberius) had powers to define who was a god. 

Jesus proved this was crazy! It was a nonsense because everyone knew Christ was God. He had multiple witnesses.  High priests and worshipers, Pilate, the legions and the whole of the population of Jerusalem had seen him rise from the dead and ascend to heaven. This knowledge is confirmed in many early writings of the centuries.
3. The Temple was the center of Christian worship. The ekklesia met in the Temple. The ekklesia also met in areas outside the Roman Empire, where the number of representatives was always a multiple of 12. The early writings tell how the apostles visited some of these Israelite areas.
In the Empire Christians giving public speeches about the resurrection of Jewish Christ and his coming again to the Temple to judge them would be worse than doing the same thing in the Soviet Union or Nazi Germany! The Roman Empire was a military dictatorship. It then destroyed the Temple! That did not change the resurrection as a fact! But it's when the extirpation of Jews and Christians began. They were made slaves, thrown underground to work in the mines, never to see sunlight again.
4. What the historians do not deal with -- the immediate destruction of much paganism because of the Resurrection. It showed paganism was false. The result of destroying the Temple? Not what the Romans expected. The Roman pantheon was DESTROYED. No one spoke much of Mars and Jupiter, Venus again. Nor do they have worshipers today! In the second century even the emperors recognized that Jesus was God! See Justin Martyr. The pagan priests (pontiffs) turned the people to sun worship and then to Mithraism.

The mists and mystery of a 'lost century' only exist for those who do not believe in the Resurrection!

Question: Was Lazarus the Beloved Disciple and author of the Gospel?

This is an interesting alternative theory but I don't think it is correct. One should not always believe 'tradition' without question, but in this case John seems designated. Why?
Clearly Lazarus was a beloved disciple. Jesus wept at his death. But so were many others 'beloved'.
Why should anyone not mention his name that he is the author of a book? There are several reasons. One is modesty. That semi-anonymity seems to be the reason that the writer of the fourth gospel can modestly describe his own activities and also the prophecies of his own future without admitting his name.
However Lazarus of Bethany is mentioned by name in John 11.  Because Lazarus is mentioned by name in the incident where he is resurrected, it is unlikely that, if he were the author, he would hide his name at the end of the book.
A second reason for anonymity is that by exposing a name the enemies of he gospel might persecute and kill that person as a special target. Lazarus was a major target as he could witness to his own resurrection! As mentioned in J3, p22, 685ff etc the enemies wished to kill him, but were perhaps afraid to do so. If they killed him who could say he would not rise from the dead again by a miracle?! That would hardly silence him! Instead they cast him and his sister into an open boat on the Mediterranean expecting them to die and disappear. They landed in France and went perhaps to Britain. 
John the apostle is a more likely candidate for the authorship of he book as he was one of the four leaders of the twelve. He also stayed in Israel where he was later involved with the Temple, possibly after the death of James.
There are a number  of other incidences of where the early gospels show discretion and then the later gospel of John reveals the name, presumably when the danger was over. One example is the name of the servant of the high priest whose ear Peter sliced off. His life would also have been threatened in the early years, up to the end of Caligula's reign with its major persecution and planned ethnocide.  Afterwards the danger subsided or he might have left Israel or even died. 

Caesar's Edict: Proof of Resurrections

The following archaeological Proof of the Resurrection is included in the latest version of the book. Many documented physical resurrections took place -- for centuries! The Romans were faced with empty tombs  -- where the body was missing but the other articles were left. Hence, not grave robbery! There are also numerous historical confirmations not included here. Roman emperors, like Tiberius and later second century ones, acknowledged the resurrection of Christ was a fact. These events were a major incentive and proof for those who gave their lives in the pagan persecutions. Christians preferred to die for the Creator God who could resurrect rather than offer a pinch of incense to the pagan gods or to a 'divine' Caesar like Caligula. Roman pagan gods .lost credibility.
The Resurrection of Christ and physical resurrections of Christians -- and the Roman Emperors acknowledgement of them -- led to the destruction of the pagan system. This is why Constantine declared the Roman Empire 'Christian'. For the majority of the citizens, the pagan gods were dead!
