Aurelius and Natalia (died 852) were a married Christian couple who were executed by Abd ar-Rahman II, the Emir of Córdoba for refusing to renounce their faith.
[1] When he was older, Aurelius, now a Christian, married Sabigotho, a girl from a Muslim family.
Living in the Umayyad state of Córdoba, the couple had a daughter and secretly practised Christianity.
Horrified by this event, Aurelius and Natalia decided that they could no longer hide their beliefs.
They are counted among the Martyrs of Córdoba, 48 Christians who were executed in that city between 850 and 859 AD According to Catholic Exchange, the significance of Aurelius and Natalia is that it is futile for Christians to try and hide their faith in Christ, and that He will honor before God those who have the courage to speak up.
