ts. Mark and Marcellian (d. 286 A.D.) were twin brothers who were martyred for their faith in Rome under Emperor Diocletian. According to legend they were both deacons from a distinguished family who were thrown into prison for being Christians. Their mother and father, who were pagans, visited their sons in prison and pleaded with them to return to the worship of false gods so that they could be saved. At the same time, St. Sebastian also visited the brothers and encouraged them to stand strong in their faith. St. Sebastian's exhortation was so persuasive that the parents of Marcellian and Mark were converted, along with several friends who were present, as well as the other prisoners. All of these new Christian converts were eventually martyred alongside Mark and Marcellian. The brothers had their feet nailed to a wood post, and later their bodies were pierced with lances. Their feast day is June 18th. For more information please see morningoffering.com/2022-06-18/ and https://catholicsaints.info/saint-mark/.
