Pascendi Dominici Gregis: On the Doctrines of the Modernists
20 With this principle of immanence is connected another which may be called the principle of divine permanence . It differs from the first in much the same way as the private experience differs from the experience transmitted by tradition. An example will illustrate what is meant, and this example is offered by the Church and the Sacraments. The Church and the Sacraments, they say, are not to be regarded as having been instituted by Christ Himself. This is forbidden by agnosticism, which sees in Christ nothing more than a man whose religious consciousness has been, like that of all men, formed by degrees; it is also forbidden by the law of immanence which rejects what they call external application ; it is further forbidden by the law of evolution which requires for the development of the germs a certain time and a certain series of circumstances; it is, finally, forbidden by history, which shows that such in fact has been the course of things. Still it is to be held that both Church and Sacraments have been founded mediately by Christ. But how? In this way: All Christian consciences were, they affirm, in a manner virtually included in the conscience of Christ as the plant is included in the seed. But as the shoots live the life of the seed, so, too, all Christians are to be said to live the life of Christ. But the life of Christ is according to faith, and so, too, is the life of Christians. And since this life produced, in the courses of ages, both the Church and the Sacraments, it is quite right to say that their origin is from Christ and is divine. In the same way they prove that the Scriptures and the dogmas are divine. And thus the Modernistic theology may be said to be complete. No great thing, in truth, but more than enough for the theologian who professes that the conclusions of science must always, and in all things, be respected. The application of these theories to the other points We shall proceed to expound, anybody may easily make for himself.
