Euthymius Zigabenus or Zigadenus or Zygadenus (Greek: Εὐθύμιος Ζιγαβηνός or Ζιγαδηνός; died after 1118) was a 12th-century monk and commentator on the Bible. He was a friend of the Byzantine emperor Alexius I Comnenus, for whom he wrote a lengthy work on heresies, Panoplia Dogmatica or Panoply of Doctrine (or "Full Armour of Belief"). This began in the apostolic era and continued down to the Bogomils, some of whom he personally examined. The entry on the Bogomils is our main source of information about them. Nothing is known about his life.
He was a monk and lived in the monastery of the Virgin Mary near Constantinople. He was favoured by both the emperor and his daughter Anna Comnena, who extols his learning and piety in her Alexiad.
He also wrote a commentary on the Psalms, one on the four gospels, and one on the letters of St. Paul. These are based mainly on patristic sources.
Spurious works under his name include "The Exposition of the Nicene-Constantinople Creed" and "Dialogue with a Muslim".
The Pericope Adulterae in John
Bruce Metzger argued that "No Greek Church Father prior to Euthymius Zigabenus (twelfth century) comments on this passage, and Euthymius declares that the accurate copies of the Gospel do not contain it". But this is somewhat misleading, in that Didymus the Blind discusses it, albeit not in John's gospel, and Jerome also refers to it, among others.
- But it is necessary to know that the things which are found from this place to that where it is said: Therefore Jesus again spoke of these things saying, I am the light of the world: in the more exact copies, these are either not found, or marked with an obelus, because they seem illegitimate and added. And the argument for this is because Chrysostom makes no mention anywhere of this; but for us we must also declare that this, because it is not without usefulness, is the chapter on the woman taken in adultery, which is placed between these.
