often attributed to Isidore of Seville: Arthur-Marie Le Hir asserts that evidences like Isidore and the Ambrose Ansbert Commentary on Revelation show early circulation of the Vulgate with the verse and thus also should be considered in the issues of Jerome's original Vulgate text and the authenticity of the Vulgate Prologue. Cassiodorus has also been indicated as reflecting the Vulgate text, rather than simply the Vetus Latina. Commentary on Revelation Ambrose Ansbert refers to the scripture verse in his Revelation commentary: "Ambrose Ansbert, in the middle of the eighth century, wrote a comment upon the Apocalypse, in which this verse is applied, in explaining the 5th verse of the first chapter of the Revelation". Medieval use Fourth Lateran Council In the Middle Ages a Trinitarian doctrinal debate arose around the position of Joachim of Florence (1135–1202) which was different from the more traditional view of Peter Lombard (c. 1100–1160). When the Fourth Council of the Lateran was held in 1215 at Rome, with hundreds of Bishops attending, the understanding of the heavenly witnesses was a primary point in siding with Lombard, against the writing of Joachim. The Council thus printed the verse in both Latin and Greek, and this may have contributed to later scholarship references in Greek to the verse. The reference to "some manuscripts" showed an acknowledgment of textual issues, yet this likely related to "and the three are one" in verse eight, not the heavenly witnesses in verse seven. The manuscript issue for the final phrase in verse eight and the commentary by Thomas Aquinas were an influence upon the text and note of the Complutensian Polyglot. Latin commentaries In this period, the greater portion of Bible commentary was written in Latin. The references in this era are extensive and wide-ranging. Some of the better-known writers who utilized the comma as scripture, in addition to Peter Lombard and Joachim of Fiore, include Gerbert of Aurillac (Pope Sylvester), Peter Abelard, Bernard of Clairvaux, Duns Scotus, Roger of Wendover (historian, including the Lateran Council), Thomas Aquinas (many verse uses, including one which has Origen relating to "the three that give witness in heaven"), William of Ockham (of razor fame), Nicholas of Lyra and the commentary of the Glossa Ordinaria. Greek commentaries Emanual Calecas in the 14th and Joseph Bryennius (c. 1350–1430) in the 15th century reference the comma in their Greek writings. The Orthodox accepted the comma as Johannine
