Pope Marcellinus was the bishop of Rome from 30 June 296 to his death in 304. A historical accusation was levelled at him by some sources to the effect that he might have renounced Christianity during Emperor Diocletian's persecution of Christians before repenting afterwards, which would explain why he is omitted from lists of martyrs. The accusation is rejected, among others, by Augustine of Hippo. He is today venerated as a saint in the Catholic Church and in the Serbian Orthodox Church.
