Twenty years after the condemnation of the teachings of Michael Bajus, arose in Spain the controversy between the Jesuits and the Dominicans concerning the doctrine of Grace. The leading representative of the latter was Domingo Bañez of Salamanca (†1604) and of the Jesuits, Luis Molina, professor at Evera (†1600). The issues were referred to Rome more immediately in connection with the treatise by Molina, _Concordia liberi arbitrii cum gratiae donis_, which had been denounced by the Dominicans, and, between 1602 and 1606, a series of disputations were carried on under the direction of Clement VIII and of Paul V at the sessions of the Congregation _de Auxiliis_. In December, 1611, a decree of Paul V prohibits the printing thereafter, without the specific authorisation of the Inquisition, of any writing having to do with the contest. This decree was confirmed by Urban VIII in 1625 and 1641, and again by Alexander VII in 1657. The latter added a prohibition for the printing, without the approval of the Inquisition, of any writings which were concerned with the _materia auxiliorum divinorum ex professo_, or which brought this subject-matter into print in connection with commentaries on the writings of Thomas Aquinas. This general prohibition is entered in Alexander’s Index under the term _libri_ and, since the time of Benedict, finds place in the _Decreta Gen._, ii, 1. Under the terms of the _Decreta_, all writings under this heading, printed since 1657 without a specific approval, are to be held as condemned. The Index contains, however, but three specific titles and these of comparatively insignificant monographs. Reusch points out that the bitter controversial treatises of the Dominican, Hyacinth Serry, and of the Jesuit, Livinus de Meyer, failed to be recorded in the Index.[27]
