See also Kurt Aland and Barbara Aland, The Text of the New Testament, 2nd ed. (Grand Rapids, MI: Eerdmans, 1989), p. 287. Systematic separation of words and sections of the text did not occur until the 11th century, and punctuation and accentuation were fairly elementary until the seventh century (see Léon Vaganay and Christian-Bernard Amphouz, An Introduction to New Testament Textual Criticism, 2nd ed.[Cambridge: Cambridge Univ. Press, 1991], pp. 8–9).
