Rom.14:11 "For it is written (Isa.45:23), As I live, saith the Lord, every knee shall bow to me, and every tongue shall confess to God."
The historian, Publius Cornelius Tacitus, was a non-Christian, Roman Senator
who recorded certain facts about Jesus Christ and Christians in his works.
In The Fire of Rome, by Karl von Piloty, 1861, says according to Tacitus, the Roman Emperor, Nero, targeted Christians as those responsible for the burning of Rome. The Roman historian and senator, Tacitus, referred to Christ, his execution by Pontius Pilate, and the existence of early Christians in Rome in one page of his final work, Annals (written around AD 116), book 15, chapter 44.
The context of the passage is the six-day conflagration of Rome that burned much of the city in AD 64 during the reign of Roman Emperor Nero. The passage is one of the earliest non-Christian references to the origins of Christianity, the execution of Christ described in the canonical gospels, and the presence and persecution of Christians in 1st-century Rome.
Scholars generally consider Tacitus' reference to the execution of Jesus by Pontius Pilate to be both authentic, and of historical value as an independent Roman source. Eddy and Boyd state that it is now "firmly established" that Tacitus provides a non-Christian confirmation of the crucifixion of Jesus.
Historian Ronald Mellor has stated that The Annals is "Tacitus's crowning achievement" which represents the "pinnacle of Roman historical writing". Scholars view it as establishing three separate facts about Rome around AD 60: (1) that there were a sizable number of Christians in Rome at the time, (2) that it was possible to distinguish between Christians and Jews in Rome, and (3) that at the time pagans made a connection between Christianity in Rome and its origin in Roman Judea.
The Annals passage (15.44), which has been subjected to much scholarly analysis, follows a description of the six-day Great Fire of Rome that burned much of Rome in July 64 AD.
