Harris, J. Rendel. "Additional Notes on the Teaching." The Teaching of the Apostles, newly edited, with facsimile text and a commentary, for the Johns Hopkins University, Baltimore, from the MS. of the Holy Sepulchre (Convent of the Greek Church) Jerusalem. Baltimore: Publication Agency of the Johns Hopkins University, 1887, 97-107.
Harris provides a number of miscellaneous notes about the Didache. He observes a variety of opinions about the two titles, suggesting that the work may well have circulated under one or the other title, but not normally with both (Harris 1887, 97).
The Two Ways teaching appears in one form or another not only in Jewish thought, but also in Greek philosophy, though the descriptions of good and evil differ (Harris 1887, 97). Harris observes thatGreek philosophy will often use the letter gamma to indicate a duality. Harris does trace many of the ideas from the Two Ways to biblical and Judaistic roots (Harris 1887, 98-99).
The customs of baptism and prayers are similarly well rooted in biblical and early Christian roots (Harris 1887, 99-101). Harris considers the Didache to be a document which accords with historic Christianity.
Harris also finds the Didache's attitude toward traveling prophets to be biblically appropriate. Christians care for those who serve them in the Word of God, but they do not feed the ministers' greed or avarice (Harris 1887, 104). It is entirely appropriate that those who can work for their living should do so (Harris 1887, 105).
