it was so widely diffused and acknowledged in the West as to be appealed to by him bona fide in his contest with his Arian opponents." Fulgentius of Ruspe In the 6th century, Fulgentius of Ruspe, like Cyprian a father of the North African Church, skilled in Greek as well as his native Latin, used the verse in the doctrinal battles of the day, giving an Orthodox explanation of the verse against Arianism and Sabellianism. From ("Reply against the Arians"; Migne (Ad 10; CC 91A, 797)): Then Fulgentius discusses the earlier reference by Cyprian, and the interweaving of the two Johannine verses, John 10:30 and 1 John 5:7. Another heavenly witnesses reference from Fulgentius is in (Migne (Frag. 21.4: CC 01A,797)): Also from Fulgentius in : Today these references are generally accepted as probative to the verse being in the Bible of Fulgentius.

Cassiodorus Cassiodorus wrote Bible commentaries, and was familiar with Old Latin and Vulgate manuscripts, seeking out sacred manuscripts. Cassiodorus was also skilled in Greek. In , first published in 1721 by Scipio Maffei, in the commentary section on 1 John, from the Cassiodorus corpus, is written: Thomas Joseph Lamy describes the Cassiodorus section and references that Tischendorf saw this as Cassiodorus having the text in his Bible. However, earlier "Porson endeavoured to show that Cassiodorus had, in his copy, no more than the 8th verse, to which he added the gloss of Eucherius, with whose writings he was acquainted."
