Writings during the lifetime of Jesus?

[Minimalist]

For the first 4 centuries AD, the Romans did their best to suppress and persecute the early Christians in an attempt to stamp out the evidence.

The first empire wide "persecution" of xtians occurred in the mid-3d century under the emperor Decius.

In January 250, Decius issued an edict for the suppression of Christianity. The edict itself was fairly clear:

While Decius himself may have intended the edict as a way to reaffirm his conservative vision of the Pax Romana and to reassure Rome's citizens that the empire was still secure, it nevertheless sparked a "terrible crisis of authority as various [Christian] bishops and their flocks reacted to it in different ways." Measures were first taken demanding that the bishops and officers of the church make a sacrifice for the Emperor, a matter of an oath of allegiance that Christians considered offensive. Certificates were issued to those who satisfied the pagan commissioners during the persecution of Christians under Decius. Forty-six such certificates have been published, all dating from 250, four of them from Oxyrhynchus. Christian followers who refused to offer a pagan sacrifice for the Emperor and the Empire's well-being by a specified date risked torture and execution. A number of prominent Christians did, in fact, refuse to make a sacrifice and were killed in the process including Pope Fabian himself in 250 and "anti-Christian feeling[s] led to pogroms at Carthage and Alexandria." In reality, however, towards the end of the second year of Decius' reign, "the ferocity of the [anti-Christian] persecution had eased off, and the earlier tradition of tolerance had begun to reassert itself." The Christian church though never forgot the reign of Decius whom they labelled as that "fierce tyrant".

If you can find an imperial edict prior to this by all means, let's see it.
