Tacitus
"In his Annals, supposedly written around 107 CE, Tacitus purportedly related that the Emperor Nero (37-68) blamed the burning of Rome during his reign on "those people who were abhorred for their crimes and commonly called Christians." Since the fire evidently broke out in the poor quarter where fanatic, agitating Messianic Jews allegedly jumped for joy, thinking the conflagration represented the eschatological development that would bring about the Messianic reign, it would not be unreasonable for authorities to blame the fire on them.
However, it is clear that these Messianic Jews were not (yet) called "Christiani." In support of this contention, Nero's famed minister, Seneca (5?-65), whose writings evidently provided much fuel for the incipient Christian ideology, has not a word about these "most-hated" sectarians."
"the Tacitean passage next states that these fire-setting agitators were followers of "Christus" (Christos), who, in the reign of Tiberius, "was put to death as a criminal by the procurator Pontius Pilate." The passage also recounts that the Christians, who constituted a "vast multitude at Rome," were then sought after and executed in ghastly manners, including by crucifixion.
However, the date that a "vast multitude" of Christians was discovered and executed would be around 64 CE, and it is evident that there was no "vast multitude" of Christians at Rome by this time, as there was not even a multitude of them in Judea. Oddly, this brief mention of Christians is all there is in the voluminous works of Tacitus regarding this extraordinary movement, which allegedly possessed such power as to be able to burn Rome.
Also, the Neronian persecution of Christians is unrecorded by any other historian of the day and supposedly took place at the very time when Paul was purportedly freely preaching at Rome (Acts 28:30-31), facts that cast strong doubt on whether or not it actually happened. Drews concludes that the Neronian persecution is likely "nothing but the product of a Christian's imagination in the fifth century."
Eusebius, in discussing this persecution, does not avail himself of the Tacitean passage, which he surely would have done had it existed at the time. Eusebius's discussion is very short, indicating he was lacking source material; the passage in Tacitus would have provided him a very valuable resource."
"Even conservative writers such as James Still have problems with the authenticity of the Tacitus passage: For one, Tacitus was an imperial writer, and no imperial document would ever refer to Jesus as "Christ." Also, Pilate was not a "procurator" but a perfect, which Tacitus would have known. Nevertheless, not willing to throw out the entire passage, some researchers have concluded that Tacitus "was merely repeating a story told to him by contemporary Christians."
"Based on these and other facts, several scholars have argued that, even if the Annals themselves were genuine, the passage regarding Jesus was spurious. One of these authorities was Rev. Taylor, who suspected the passage to be a forgery because it too is not quoted by any of the Christian fathers, including Tertullian, who read and quoted Tacitus extensively.
Nor did Clement of Alexandria notice this passage in any of Tacitus's works, even though one of this Church father's main missions was to scour the works of Pagan writers in order to find validity for Christianity. As noted, the Church historian Eusebius, who likely forged the Testimonium Flavianum, does not relate this Tacitus passage in his abundant writings.
Indeed, no mention is made of this passage in any known text prior to the 15th century."
"The tone and style of the passage are unlike the writing of Tacitus, and the text "bears a character of exaggeration, and trenches on the laws of rational probability, which the writings of Tacitus are rarely found to do." Taylor further remarks upon the absence in any of Tacitus's other writings of "the least allusion to Christ or Christians."
In his well-known Histories, for example, Tacitus never refers to Christ, Christianity or Christians. Furthermore, even the Annals themselves have come under suspicion, as they themselves had never been mentioned by any ancient author...."
"In any event, even if the Annals were genuine, the pertinent passage itself could easily be an interpolation, based on the abundant precedents and on the fact that the only manuscript was in the possession of one person, de Spire. In reality, "none of the works of Tacitus have come down to us without interpolations.""
Ignatius
So of the 15 letters, he supposedly wrote 8 of them are known forgeries. Being (Tarsians, Antiochians, Hero, Philippians, Maria to Ignatius, Mary, 1st. St. John, 2nd St. John, Virgin Mary)
As for the other 7 (Polycarp, Ephesians, Magnesians, Philadelphians, Romans, Smyrnaeans, Trallians) there is still some debate among scholars.
"They purport to be written by Ignatius, who lived about 110 AD. We believe it is clear, however, that they are all no earlier than 220 AD, more likely 250 AD. Although they are forgeries, they do represent the views of the author in the time of 250 AD."
"We see a clear change from the Bible pattern, from a plurality of Elders (also called bishops), deacons and saints, to a single Bishop who ruled the congregations and under him were a plurality of elders, then deacons and saints. At this point in history, congregations were still autonomous and independent, but we also see the seeds of development for the Papal system, where one man rules over all churches world wide which first occurred in 606 AD."
"Within one of the "7 genuine Ignatius letters", is a powerful clue it is clearly a forgery from a later time. The very first historical reference to the "Catholic Church" is nestled warmly between very strong commands to obey the bishop as you would Jesus Christ and the only valid baptism or communion service is one by the bishop's authority. We feel that is it no coincidence that the first historical reference to the church as the "Catholic Church" is contained within one of the "7 genuine Ignatius letters". We feel it is proof enough to reject all as forgeries."
