Matthew And The Didache

the long version

"There are significant agreements between the Didache and the Gospel of Matthew as these writings share words, phrases and motifs. In modern scholarship, there seems to be an increasing reluctance, however, to support the thesis that the Didache used Matthew. And, indeed, such a close relationship might equally suggest that both documents were created in the same historical and geographical setting, for example in the Greek-speaking part of Syria." --Book Jacket.
