Heidegger's Bible Handbook: Luke: Style of Greek

7. Of what sort is the diction?

That Luke wrote in Greek, is doubted by no one.The style of his writing is vivid, and clear in historical manner, with the vestiges of Syriasm and Latinism immediately left behind.He descends to the popular manner of narration, more polished indeed than Matthew and Mark, but not rising to Demosthenic pomp,[1] and the Heathen grandeur of words.Thus Jerome writes on Isaiah 6, The ancient writers of the Church relate that the Evangelist Luke was most learned in the art of medicine, and that he understood Greek letters better than Hebrew.Whence also his speech both in the Gospel and in Acts is more elegant, and smells of secular eloquence.

[1] Demosthenes (384-322 BC) was a Greek orator and statesman.
