Antilegomena

Antilegomena, a direct transliteration of the Greek ἀντιλεγόμενα, refers to written texts whose authenticity or value is disputed.
Eusebius in his Church History written c. 325 used the term for those Christian scriptures that were "disputed" or literally those works which were "spoken against" in Early Christianity, before the closure of the New Testament canon. It is a matter of scientific discussion whether Eusebius divides his books into three groups of homologoumena ("accepted"), antilegomena, and heretical — or four by adding a notha ("spurious") group. The antilegomena or "disputed writings" were widely read in the Early Church and included the Epistle of James, the Epistle of Jude, 2 Peter, 2 and 3 John, the Apocalypse of John, the Gospel of the Hebrews, the Apocalypse of Peter (unique in being the only book never accepted as canonical which was commentated upon by a Church Father), the Acts of Paul, the Shepherd of Hermas, the Epistle of Barnabas and the Didache. The term "disputed" should therefore not be misunderstood to mean "false" or "heretical"; rather, there was disagreement in the Early Church on whether or not the respective texts deserved canonical status.
