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.
