CHRISTIANITY
The Didache
The Teaching of the Twelve Apostles: a first-to-second-century manual of Christian conduct, baptism, fasting and the eucharist — the earliest church order known, rediscovered in 1873.
The Didache runs to 16 chapters, 16 passages. The whole of it is held here and free to read, searchable by reference or by the words in it.
The edition held here is Ante-Nicene Fathers, in English, in the public domain, from Wikisource (Ante-Nicene Fathers, Vol. VII).
It sits on the estate's shelf of 106 sacred works, beside the complete Douay-Rheims Bible, an atlas of the places named in scripture, a timeline and a genealogy.
