Bede : And a certain woman named Lydia, a dealer in purple, of the city of Thyatira, a worshipper of God, heard, etc. He says "a dealer in purple" meaning a seller of purple, as we also find in another translation, which in Greek is called πορφυρόπωλις. Properly, however, the woman who first believed with the Apostle preaching in Illyricum is said to be a dealer in purple. It signifies the Church, which is accustomed to sell, as it were, purple, because it does not hesitate to shed its blood for Christ, so that through this it can obtain eternal life. Indeed, purple rightly designates the shedding and color of blood, and by the property of its nature, which is made from the blood of shellfish. Lydia, however, forced the Apostle and his companions to enter her house and to stay there, because the Church received the preaching of the gospel with internal devotion of the heart, despite being rejected by the Jews. — Retractions on Acts John Chrysostom : "And a certain woman": a woman and she of low condition, from her trade too: but mark in her a woman of elevated mind. In the first place, the fact of God's calling her bears testimony to her. "And a certain woman, named Lydia, a seller of purple": observe how the writer of the history is not ashamed of the occupations of the converts: moreover neither was this city of the Philippians a great one. Having learnt these things, let us also be ashamed of no man. Peter abides with a tanner; Paul with a woman who was a seller of purple, and a foreigner. Where is pride? "Whose heart the Lord opened." Therefore we need God, to open the heart: but God opens the hearts that are willing: for there are hardened hearts to be seen. "So that she attended to the things which were spoken of Paul." The opening, then, was God's work, the attending was hers: so that it was both God's doing and man's. — Homily on Acts 35
