"Rejoice in the Lord, O city of Thessaloniki..."

St. Demetrios the Great Martyr and Myrrhstreamer (Source)

Rejoice in the Lord, O city of Thessaloniki, exalt and dance, shining forth with faith, for Demetrios, the all-glorious Champion and Martyr of the truth holds you as a treasure in his bosom, and, beholding the receiving of wondrous healings, and seeing the casting down of the audacity of the Barbarians, give thanks to the Savior, crying out: Glory to You, O Lord.
-Idiomelon of the Litia in the First Tone, by George Sikeliotos
