St. Agnes of Rome (3rd century)
Agnes was twelve when she was dragged to a Roman Temple, tortured, and threatened with rape. When she refused to deny Christ, she was burned and beheaded. Her name is mentioned in the Eucharistic Prayers of Mass.

Reflections from the Saints

Christ made my soul beautiful with the jewels of grace and virtue. I belong to Him whom the angels serve.
