Emperor Julian the Apostate.
Flavius Claudius Iulianus (331–June 26, 363), was a Roman Emperor (361–363) of the Constantinian dynasty. He was the last pagan Roman Emperor, and tried to promote the Roman religious traditions of earlier centuries as a means of slowing the spread of Christianity. Because of this persecution the Christian countries lost the protection of the State and now had to form their own Armies. Rome being a country caused  the papacy to form their own Army and government which later lead to the corruption that inflicts secular activities.

Saint Bibiana, Virgin and Martyr December 2
According to tradition. Bibiana belonged to a family of martyrs. When persecution broke out in ROME during the reign of Emperor Julian the Apostate, her Father Flavian, former prefect of the city, was branded in the face with a hot iron and sent into exile. Her mother, Dafrosa, was beheaded, Bibiana herself was handed over to a wicked woman named Rufina, to be corrupted by her; but she proved stronger than her temptress, and was finally condemned to death. About the year 363, she was beaten with leaded whips until she died. ~ St. Bibiana, Maryknoll Missal 1959
