Sixtus of Siena: divine Old Testament Scriptures not falsified; five observations against corruption charges
From all this, judgment is made about the printed exemplars we still use, whose typographical slips are known to the learned. Hence Sixtus of Siena (Bibliotheca book 8, heresy 2) says it cannot be said that the divine Scriptures of the Old Testament have been falsified by the malice of Jews or of Christians.
For greater clarity of the matter, let these be observed: (1) Not every change proves corruption. Hence Benedictus Arias Montanus in the preface to volume 1 of the Bibles says the Hebrew books we use were not corrupted by Jewish fraud; and even if some change was made, yet no word or letter or point ever existed that was not observed in the Masoretic tradition. (2) The papists deal with such Old Testament corruption in order that the Latin Vulgate version may flow purer than its source. They will demonstrate that on the Greek Kalends. (3) Corruption asserted by some fathers rests not on demonstration but on suspicion. For they were ignorant of the Hebrew tongue — unless perhaps you except Justin lightly tinged with these letters, and Origen and Jerome excellently steeped in them, who with us vindicate the Hebrew text from corruptions. (4) Many fathers complain of corruption not of the sources but of the versions of the Seventy, Aquila, Symmachus, Theodotion, and others. (5) The suspicion of corruption rests on the papists' false hypothesis pronouncing the Latin version authentic, so that no one dares reject it under any pretext (Council of Trent session 4).
Latin
Ex his vero omnibus fit judicium de excusis exemplaribus quibus hodieque utimur, quorum sphalmata typographica eruditis nota sunt. Hinc Sixtus Senensis l.8. biblioth. haeres. 2. dici ait non potest divinas Veteris Testamenti Scripturas aut Judaeorum aut Christianorum malitia falsatas. Ubi ad majorem rei evidentiam haec sunto observanda. 1. Non omnem mutationem arguere corruptionem. Hinc Bened. Arias Montanus praefatione tom.1. Bibliorum ait libros Hebraicos quibus utimur non fuisse Judaeorum fraude corruptos, etsi fuerit aliqua mutatio facta, tamen nullum verbum vel elementum vel punctum olim fuisse quod in Thesauro quem Masoreth appellant non fuerit observatum. 2. De tali V.T. corruptela pontificios agere, ad quam Latina versio vulgata fonte suo purior fluat. Eam vero demonstrabunt ad Kalendas Graecas. 3. Corruptionem a quibusdam patribus assertam non niti demonstratione sed suspicione. Ignari enim fuere Hebraeae linguae, si forsan excipias Justinum his literis leviter tinctum, Origenem & Hieronymum iis egregie imbutum, qui textum Hebraeum a corruptelis nobiscum vindicat. 4. Multos patrum queri de corruptione non fontium sed versionum LXX, Aquilae, Symmachi, Theodotionis aliorum. 5. Suspicionem corruptionis niti falsa hypothesi pontificiorum, pronunciantium Latinam versionem authenticam, ut nemo illam quovis praetextu rejicere audeat (Concil. Trid. sess.4).
