St. Eusebius of Rome

Eusebius is remembered through the ancient Roman church known as the titulus Eusebii. The survival of that name matters: it preserves the memory of a real Roman Christian whose life became inseparable from a worshipping community. As founder, he received an annual commemorative Mass, and that faithful remembrance developed into the liturgical cult of a saint.

The later biography is more dramatic. It presents Eusebius as a priest who resisted the Arian emperor Constantius, celebrated the sacred mysteries in his own house, and died after being confined there. This life explains that this account cannot be treated as reliable history. The caution belongs in its proper place, after the secure center of the feast. Eusebius remains tied to a real church and a real Roman cult even though few personal details survive. His memory shows how the Church can preserve the name of a faithful Christian when a full written biography has been lost.
