Saint Julius the Veteran, also referred to as Julius of Durostorum, is a Roman Catholic, Anglican and Eastern Orthodox saint and martyr.
Saint Julius’ date to conversion is unknown but he served as a Roman soldier for 27 years first as a conscript, then returning as a [veteran], totaling seven military campaigns in total. Given the years and locations in which Julius served, Rev. Herbert Musurillo, S.J. writes that Julius likely served in the Legio XI Claudia. Julius was Christian his entire military career.
Saint Julius the Veteran was brought to trial before the prefect, Maximus, after being arrested by Maximus’ staff soldiers for refusing to make a public sacrifice to the Roman gods. Upon hearing of his military service, Maximus complimented Julius for being a wise and serious man.
In gratitude for his military service, Maximus proposed Saint Julius a bargain: if Saint Julius offered the public sacrifice, Maximus would accept blame for the sin of the sacrifice and would give Saint Julius freedom, a ten-year bonus payment, and immunity from future charges. Saint Julius declined the offer and was sentenced to death. Saint Julius was killed by the sword in Durostorum, the Roman camp in Moesia Inferior.
