In Cajetan’s case, to speak of his commentaries on Scripture is to speak not of the feathers of the peacock but of its feet.  For however much his great mind is worthy of admiration in his other works, yet in these, where he allowed himself to be led astray by a guide more versed in Hebrew grammar than in the divine mysteries, he remains inglorious (St Robert Bellarmine, Vindiciae pro libro secundo De Verbo Dei, ad cap. X).
