Published for the first time by Paul de Lagarde in the extant Syriac, this volume reproduces the initial edition of the Didascalia Apostolorum. This important document, which purports to have been written by the apostles is a third-century pseudepigraphon. Presenting a view of the Catholic doctrine as it was believed to have been held by the original apostles, the topics addressed include worship, doctrine, and Christian discipline. For the Syriac scholar wishing to engage a foundational document in the early history of the church, this publication represents an excellent starting point.
