Pascendi Dominici Gregis §11

¹¹ So far, Venerable Brethren, there has been no mention of the intellect. Still it also, according to the teaching of the Modernists, has its part in the act of faith. And it is of importance to see how. - In that sentiment of which We have frequently spoken, since sentiment is not knowledge, God indeed presents Himself to man, but in a manner so confused and indistinct that He can hardly be perceived by the believer. It is therefore necessary that a ray of light should be cast upon this sentiment, so that God may be clearly distinguished and set apart from it. This is the task of the intellect, whose office it is to reflect and to analyse, and by means of which man first transforms into mental pictures the vital phenomena which arise within him, and then expresses them in words. Hence the common saying of Modernists: that the religious man must ponder his faith. - The intellect, then, encountering this sentiment directs itself upon it, and produces in it a work resembling that of a painter who restores and gives new life to a picture that has perished with age. The simile is that of one of the leaders of Modernism. The operation of the intellect in this work is a double one: first by a natural and spontaneous act it expresses its concept in a simple, ordinary statement; then, on reflection and deeper consideration, or, as they say, by elaborating its thought , it expresses the idea in secondary propositions, which are derived from the first, but are more perfect and distinct. These secondary propositions, if they finally receive the approval of the supreme magisterium of the Church, constitute dogma.
