What's the story of Lydia in the Bible? Lydia of Thyatira is a woman introduced in the New Testament who is considered as the first recorded convert to Christianity in Europe. Several Christian denominations have sanctioned her as a saint. She is regularly known as “St. Lydia” or simply “The Woman of Purple.” She was commonly identified as a dealer of purple cloth, which is the probable basis for the Catholic Church describing her as the “patroness of dyers.” Discover more about the story of Lydia in the Bible from the collection of scripture quotes below!
