St. Marcellus the Centurion

Marcellus was a Christian centurion serving in Spain when an imperial celebration required participation in pagan religious observances. In the account followed by Butler, he laid down the military belt, weapons, and staff that marked his office, declaring his allegiance to Jesus Christ. His action was reported to his commander, and he was imprisoned.

The case was sent across the sea to Tangier, where the official Agricolaus examined him. Marcellus acknowledged what he had done and was sentenced to death for desertion and impiety. He was beheaded on October 30. Butler places the martyrdom in 298 and follows the account preserved among the ancient acts of the martyrs.

The sentence also moved Cassian, a court notary, to refuse to record what he judged unjust. Cassian was imprisoned and later suffered his own martyrdom on a different day. Butler keeps the two commemorations distinct. The memory of Marcellus was preserved especially at León in Spain, where his relics were received and a church bore his name.
