Pliny the Younger in his letter to Roman Emperor Trajan (A.D. 112):
[The Christians] were in the habit of meeting on a certain fixed day before it was light, when they sang in alternate verses a hymn to Christ, as a god, and bound themselves by solemn oath, not to do any wicked deeds, but never to commit any fraud, theft or adultery, never to falsify their word, nor deny a trust when they should be called upon to deliver it up; after which it was their custom to separate, and them reassemble to partake of food–but food of an ordinary and innocent kind.
Emperor Trajan’s letter of reply to Pliny:
No search should be made for these people, when they are denounced and found guilty they must be punished … however, that when the party denies himself to be a Christian, and shall give proof that he is not (that is, by adoring our gods) he shall be pardoned on the ground of repentance even though he may have formerly incurred suspicion.
Ancient Roman Historian Tacitus (c. A.D. 100):
Consequently, to get rid of the report, Nero fastened the guilt and inflicted the most exquisite tortures on the class hated for their admoninations, called Christians by the populace. Christus [Christ], from whom the name had its origin, suffered the extreme penalty during the reign of Tiberius at the hands of one of our procurators, Pontius Pilatus, and a most mischievous superstition, thus checked for the moment, again broke out not only in Judea, the first source of the evil, but even in Rome, where all things hideous and shameful from every part of the world find their center and become popular.
(The Annals of Tacitus)
Accordingly, an arrest was first made of all who pleaded guilty [to being Christians]; then, upon their information, an immense multitude was convicted, not so much of the crime of firing the city, as of hatred against mankind. Mockery of every sort was added to their deaths. Covered with the skins of beasts, they were torn apart by dogs and perished, or were nailed to crosses, or were doomed to flames and burnt, to serve as a nightly illumination, when daylight had expired. Nero offered his gardens for the spectacle, and was exhibiting a show of circus, while he mingled with the people…
(The Annals of Tacitus)
Ancient Roman historian Suetonius (A.D. 117-138):
As the Jews were making constant disturbances at the instigation of Chrestus [Christ], he expelled them from Rome.
(Life of Claudius)
Punishment was inflicted on the Christians, a body of people addicted to a novel and mischievous superstition.
(Life of Nero)
I’m assuming the “mischievous superstition” and evil to which Tacitus and Suetonius refer is the Eucharist, or perhaps the belief that Christ rose from the dead. These historians were no friends of the Christians.
