Doubt came from hard passages, not missing Church decree
Third: those who doubted those books did not doubt because they failed to see them received by the churches and recommended by the ancient Fathers' tradition naming the apostles as authors.
They doubted because, without weighing the matter enough, they thought those books contained things that did not savor of the divine Spirit and did not cohere well enough with the faith taught in the other books.
So the Latin Church doubted Hebrews, because chapters six and ten seemed to favor the Novatians, who cut off all hope of pardon from those who fell after baptism.
The Apocalypse was also suspect because of the Millenarians, who misused certain places that seemed to favor them.
Jude was rejected by some because it seems to cite an apocryphal book that once circulated under the name of Enoch the patriarch.
Latin
XXXVII. Dico tertio, eos, qui de libris illis dubitarunt, dubitandi causam non habuisse, quod eos non viderent ab Ecclesiis receptos, & antiquorum Patrum eos ad Apostolos authores referentium traditione commendari: sed quod, re non satis expensa, putarent in his libris quaedam esse quae non redolerent divinum Spiritum; nec satis cohaererent cum fidei doctrina reliquis libris comprehensa. Ita dubitatum est in Ecclesia Latina de Epist. ad Hebraeos, quod capite sexto & decimo videretur favere Novatianis, qui lapsis post baptismum omnem spem veniae tollebant. Apocalypsis etiam suspecta fuit propter Millenarios, qui quibusdam ejus locis abuttebantur, quae ipsis in speciem favent. Judae vero Epistola a quibusdam rejecta fuit, quoniam videtur citare librum quendam Apocryphum, qui sub nomine Enoch Patriarchae olim circumferabatur.
