Matrona of Thessalonica
St. 'Matrona of Thessalonica is commemorated by the church March 27.
St Matrona was the servant of a Jewish woman named Pantilla, the wife of the Governor of Thessalonica. When Matrona refused to follow her mistress into the synagogue, Pantilla beat her so severly that she died a few days later, and thus received the crown of her confession. 
Kontakion in the Fourth Tone
O Lord Jesus, unto You Your lamb cries with a great voice, "O my Bridegroom, You I love; and seaking You, I now contest, and with Your baptism I am crucified and buried. I suffer for Your sake, that I may reign with You; for Your sake I die, that I may live in /you. Accept me, offered out of longing to You as a splotless sacrifice". Lord, save our souls through her intercessions, since You are great in mercy.
