Lucius I was a Roman bishop who served as pope from June 253 until his death in March 254. Born in Rome to Porphyrianus, he assumed leadership during a period of intense persecution. Shortly after his consecration, he faced banishment, though he eventually received permission to return to the city. He is recognized for his opposition to the Novationists, as he opposed their refusal to welcome Christians who had previously lapsed during times of persecution.
Life and service

During his brief papacy, Lucius worked to maintain unity within the early Church. He was praised by Cyprian for his stance against those who sought to exclude repentant believers from communion. Although historical records sometimes incorrectly labeled him a martyr, he actually died before the Valerian persecution began, making him a confessor rather than a martyr.
Veneration and relics
He is commemorated on March 4 or March 5 depending on the tradition. His remains were originally located in the catacombs of Callixtus. While a skull once attributed to him was kept in Denmark, carbon dating suggests that the relic actually belonged to a person who lived much later than the third-century pope.
