Roswell D. Hitchcock and Francis Brown have provided both the Greek text and the English translation of The Teaching of the Twelve Apostles, along with critical notes. The in-depth introduction to the texts compares The Teaching with other early Christian documents and discusses the controversies surrounding its dating, the various sources for the manuscripts, its purpose and scope, the doctrine contained therein, and much more. Philip Schaff then provides a full bibliography of Didache literature.
