An important new testimony I have not seen spoken of much in modern scholarly sources comes from Mara Bar Serapion. This letter was written around A.D. 74, and bears clear allusions both to Jesus Christ, King of the Jews, and the destruction of the Temple in 70 A.D.
https://en.wikipedia.org/wiki/Mara_bar_Serapion"What else can we say, when the wise are forcibly dragged off by tyrants, their wisdom is captured by insults, and their minds are oppressed and without defense? What advantage did the Athenians gain from murdering Socrates? Famine and plague came upon them as a punishment for their crime. What advantage did the men of Samos gain from burning Pythagoras? In a moment their land was covered with sand. What advantage did the Jews gain from executing their wise king? It was just after that their kingdom was abolished. God justly avenged these three wise men: the Athenians died of hunger; the Samians were overwhelmed by the sea and the Jews, desolate and driven from their own kingdom, live in complete dispersion. But Socrates is not dead, because of Plato; neither is Pythagoras, because of the statue of Juno; nor is the wise king, because of the 'new law' he laid down." - Mara bar Serapion, A.D. 74
There is the horribly vile polemic Toledoth Yeshu (probably written in response to the Gospel of St. Matthew, which begins with the Generations of Jesus - Toledoth Sepher, as Fr. Haydock writes, the Book of the Generations of Jesus Christ, Son of David and of Abraham in His humanity. Anti-Christian Jewish polemicists often used to take the first part of a Christian Book, then put their own sinful spin on it). Nevertheless, this vile polemic bears indirect witness from even a hostile source to all the facts of Jesus' life, including His working miracles in the Name of YHWH, which they absurdly attributed to sorcery, showing their own lack of faith in God (as if a sorcerer is going to work miracles in the Name of the Most High, and as if God's Name would accomplish this for anyone other than the true Messiah - Jesus worked miracles as God because He was the I AM). Many Jewish converts in later ages attest there are more hidden derogatory references to Jesus Christ in the Talmud. Celsus, a Jew of later times refuted by Origen, also shows acquaintance with some of these false reports (the claim that the Body of Christ was "stolen" by disciples after His death, an early Jewish fable, is also repeated) but we'll see that later.
This man was a Syrian Stoic philosopher, and yet he was able to see what the blindness of the Sanhedrin could not - that the destruction of the Temple of Jerusalem was divine judgment on an unfaithful city, as Jesus Himself had prophesied. As Fr. Eusebius documents in detail from Jewish historians themselves, the time period from 33 A.D. to 70 A.D., when time was already running out for repentance, was one of continual oppression for the Jews, and a clear call to repentance. St. James the Just of Jerusalem, held in honor by all, even the Jews, whom Josephus also mentions, was slain around A.D. 63 and at that very event, many said divine chastisement would now surely come to Jerusalem. Shortly thereafter, St. Simon, second Bishop of Jerusalem, another cousin brother of Our Lord (through Alphaeus, brother to St. Joseph, according to ancient sources) was taught by interior inspiration to leave that forsaken city. History bears complete testimony that not one Christian perished in the destruction of Jerusalem and all were forewarned about it.
And so the fall of Jerusalem in 70 A.D. is yet another part of which the OAM is talking of when it says, "the external proofs of revelation, that is, divine acts and especially miracles and prophecies as the surest signs of the divine origin of the Christian religion and I hold that these same proofs are well adapted to the understanding of all eras and all men, even of this time". Recently, there was a discovery of a section of the Gospel of St. Mark predating 50 A.D. called 7Q5. All who wish can see why this happened to Jerusalem.
