Schaff, Philip. "The Ritualistic or Liturgical Part." The Oldest Church Manual Called the Teaching of the Twelve Apostles. Second Edition, Revised and Enlarged. New York: Funk & Wagnalls, 1886, 26-27.
Chapters 7-10 and 14 of the Didache give directions about public worship. Baptism, prayer, fasting, and the Eucharist are all treated in those chapters in turn (Schaff 1886, 26). Schaff notes that while Scripture does not give directions about administration of the rites, the Didache does.
