Ss. Natalia, Aurelius and Companions
Aurelius was the son of a Muslim father and a Christian mother. He was also secretly a follower of Christianity, as was his wife Natalia, who was also the child of a Muslim father. One of Aurelius's cousins, Felix, accepted Islam for a short time, but later converted back to Christianity and married a Christian woman, Liliosa.
Under Sharia Law, all four of them were required to profess Islam. In time all four began to openly profess their Christianity, with the two women going about in public with their faces unveiled. They were all swiftly arrested as apostates from Islam.
They were given four days to recant, but they refused, and were beheaded. They were martyred with a local monk, George, who had openly spoken out against the prophet Mohammed. He had been offered a pardon as a foreigner, but chose instead to denounce Islam again and die with the others.
