PIUS IX 1846-1878
False Traditionalism (against Augustine Bonnetty) *
[From the Decree of the S.C. of the Index, 11, (15) June, 1855]
1649 1 “Although faith is above reason, nevertheless no true dissension, no disagreement can ever be found between them, since both arise from the one same immutable source of truth, the most excellent and great God, and thus bring mutual help to each other” * [cf. n.1635 and 1799]
1650 2. Reason can prove with certitude the existence of God, the spirituality of the soul, the freedom of man. Faith is posterior to revelation, and hence it cannot be conveniently alleged to prove the existence of God to an atheist, or to prove the spirituality and the freedom of the rational soul against a follower of naturalism and fatalism [cf. n.1622,1625 ].
1651 3. The use of reason precedes faith and leads men to it by the help of revelation and of grace [cf. n. 1626 ].
1652 4. The method which St. Thomas and St. Bonaventure and other scholastics after them used does not lead to rationalism, nor has it been the reason why philosophy in today’s schools is falling into naturalism and pantheism. Therefore, it is not lawful to charge as a reproach against these doctors and teachers that they made use of this method, especially since the Church approves, or at least keeps silent.*
