Apparently Cardinal Cajetan held to a canon like that which Protestants hold. William Webster wrote:"Cajetan wrote a commentary on all the canonical books of the Old Testament which he dedicated to the pope. He stated that the books of the Apocrypha were not canonical in the strict sense, explaining that there were two concepts of the term 'canonical' as it applied to the Old Testament. He gave the following counsel on how to properly interpret the decrees of the Councils of Hippo and Carthage under Augustine:Here we close our commentaries on the historical books of the Old Testament. For the rest (that is, Judith, Tobit, and the books of Maccabees) are counted by St Jerome out of the canonical books, and are placed amongst the Apocrypha, along with Wisdom and Ecclesiasticus, as is plain from the Prologus Galeatus. Nor be thou disturbed, like a raw scholar, if thou shouldest find anywhere, either in the sacred councils or the sacred doctors, these books reckoned as canonical. For the words as well of councils as of doctors are to be reduced to the correction of Jerome. Now, according to his judgment, in the epistle to the bishops Chromatius and Heliodorus, these books (and any other like books in the canon of the bible) are not canonical, that is, not in the nature of a rule for confirming matters of faith. Yet, they may be called canonical, that is, in the nature of a rule for the edification of the faithful, as being received and authorised in the canon of the bible for that purpose. By the help of this distinction thou mayest see thy way clearly through that which Augustine says, and what is written in the provincial council of Carthage.129129 Cardinal Caietan (Jacob Thomas de Vio), Commentary on all the Authentic Historical Books of the Old Tesdtament, In ult.
