These non-Christian sources mentioned Christ.
* 1.3.1 Josephus
* 1.3.2 Tacitus
* 1.3.3 Suetonius
Josephus mentioned Him twice. There is some debate about one mentioning but a second mentioning of Christ as the brother{cousin} of James the Just is considered authentic.

Also you have to wonder what caused these events in the first century:
* Saint Stephen, Protomartyr, was stoned c. 35 A.D.
* James the Great (Son of Zebedee) was beheaded in 44 A.D.
* Philip the Apostle was crucified in 54 A.D.
* Matthew the Evangelist killed by a halberd in 60 A.D.
* James the Just, beaten to death by a club after being crucified and stoned.
* Matthias was stoned and beheaded.
* Saint Andrew, St. Peter's brother, was crucified.
* Mark was beaten to death.
* Saint Peter, crucified upside-down.
* Apostle Paul, beheaded in Rome.
* Saint Jude was crucified.
* Saint Bartholomew was crucified.
* Thomas the Apostle was killed by a spear.
* Luke the Evangelist was hanged.
* Simon the Zealot was crucified in 74 A.D.
(Note: John the Evangelist according to legend was cooked in boiling hot oil but survived. He was the only one of the original twelve Apostles who was not martyred).
