Marcellinus of Carthage, martyr and saint

Year 413 (CDXIII) was a common year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Heraclianus and Lucius. The denomination 413 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Marcellinus of Carthage was a Christian martyr and saint who died in 413. He was secretary of state of the Western Roman Empire under Roman emperor Honorius and a close friend of Augustine of Hippo, as well as a correspondent of Saint Jerome. Saint Augustine dedicated the first books of his landmark The City of God to Marcellinus in 413.

A martyr is someone who suffers persecution and death for advocating, renouncing, or refusing to renounce or advocate, a religious belief or other cause as demanded by an external party. In colloquial usage, the term can also refer to any person who suffers a significant consequence in protest or support of a cause.

In Christian belief, a saint is a person who is recognized as having an exceptional degree of holiness, likeness, or closeness to God. However, the use of the term saint depends on the context and denomination. In Anglican, Oriental Orthodox, and Lutheran doctrine, all of their faithful deceased in Heaven are considered to be saints, but a selected few are considered worthy of greater honor or emulation. Official ecclesiastical recognition, and veneration, is conferred on some denominational saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church after their approval. In many Protestant denominations, and following from Pauline usage, saint refers broadly to any holy Christian without special recognition or selection.
