The Codex Sangallensis 63, designated by S in some critical editions of the Bible, is a 9th-century Latin manuscript of the New Testament. The text, written on vellum, is a version of the Vulgate and contains the text of the Acts of the Apostles, Epistles, Book of Revelation, and non-biblical material (an Etymological dictionary). The manuscript has not survived in a complete condition, some parts of it have been lost.[1] The original manuscript did not contain the Comma Johanneum (in 1 John 5:7), but it was added by a later hand on the bottom margin (see picture).[2]
