Matrona of Barcelona or Matrona of Thessalonica is a saint of the Roman Catholic Church and the Eastern Orthodox Church. She was recognized as a saint pre-congregation.
She lived in the third or fourth century. She was a young girl and a slave to the Jewish woman Pautila, wife of one of the military commanders, or governor, of Thessalonica.
According to legend, she believed in Christ from her youth. Pautila constantly constantly mocked her slave for her faith in Christ, and tried to convert her to Judaism. Saint Matrona still prayed to the Savior Christ, and secretly went to church unbeknownst to her vengeful mistress.
