Reviving the censorship
Either as a concession to the Senate, or perhaps with the idea of improving public morality, Decius endeavoured to revive the separate office and authority of the

Persecution of Christians

In late 249, Decius had issued one of the most remarkable Roman imperial edicts. From the numerous surviving texts from Egypt, recording the act of sacrifice, it appears that the edict itself was fairly clear:
[Potter 2004, p. 241]
According to D. S. Potter, Decius did not try to impose the superiority of the Roman pantheon over any other gods. It is very probable that the edict was an attempt to legitimize his position and to respond to a general unease provoked by the passing of the Roman millennium.
[Potter 2004, p. 243] 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."

relates:
One literary tradition claims that Decius was betrayed by his successor, Trebonianus Gallus, who was involved in a secret alliance with the Goths, but this cannot be substantiated and was most likely a later invention since Gallus felt compelled to adopt Decius' younger son, Gaius Valens Hostilianus, as joint emperor even though the latter was too young to rule in his own right. It is also unlikely that the shattered Roman legions would proclaim as emperor a traitor who was responsible for the loss of so many soldiers from their ranks. Decius was the first Roman emperor to die in battle against a foreign enemy.[
