Thessaloniki aka Thessalonica and Salonica, is the second-largest city in Greece and the capital of the region of Central Macedonia. The earliest known letter by Paul the Apostle was written to the early Christian church in Thessaloniki and is identified as First Thessalonians; it is among the books in the New Testament whose authorship by Paul is generally regarded by scholars as being undisputed. A later letter to the same church follows in the Christian Bible as Second Thessalonians.
