St. Eusebius, Priest and Confessor at Rome
HE is named with distinction in the Latin Martyrologies on this day. The ancient genuine Martyrology of Usuard only styles him confessor under the Arian emperor Constantius, and adds, that he was buried in the cemetery of Calixtus. His acts seem of no authority. They are published by Mombritius, and more correctly by Baluze, t. 2. Miscel. p. 141. These relate that, for opposing Pope Liberius for signing the confession of Sirmium, he was persecuted by the emperor, and imprisoned some months in his room, under which confinement he sanctified himself by continual prayer, and happily died. He is called a martyr in several modern Martyrologies.
