Note 845 — Chapter VIII · THE HEBREW SABBATH
Reading edition
Epistola Barnabæ, 15; compare Justin Martyr, Dialogus cum Tryphone, 138; Tertullian, De idolatria, 14. The “eighth day” might seem to be a natural designation for the day following the Sabbath, the seventh day; more probably, however, it is to be explained by the ancient practice of inclusive reckoning.
