25 By making such an exposition, which is above all, as We have said, theological, they will efficaciously reduce to silence those who, affirming that they scarcely ever find anything in biblical commentaries to raise their hearts to God, to nourish their souls or promote their interior life, repeatedly urge that we should have recourse to a certain spiritual and, as they say, mystical interpretation. With what little reason they thus speak is shown by the experience of many, who, assiduously considering and meditating the word of God, advanced in perfection and were moved to an intense love for God; and this same truth is clearly proved by the constant tradition of the Church and the precepts of the greatest Doctors. Doubtless all spiritual sense is not excluded from the Sacred Scripture.
