Pascendi Dominici Gregis: On the Doctrines of the Modernists
35 The Modernist apologist depends in two ways on the philosopher. First, indirectly , inasmuch as his theme is history - history dictated, as we have seen, by the philosopher; and, secondly, directly , inasmuch as he takes both his laws and his principles from the philosopher. Hence that common precept of the Modernist school that the new apologetics must be fed from psychological and historical sources. The Modernist apologists, then, enter the arena by proclaiming to the rationalists that though they are defending religion, they have no intention of employing the data of the sacred books or the histories in current use in the Church, and composed according to old methods, but real history written on modern principles and according to rigorously modern methods. In all this they are not using an argumentum ad hominem , but are stating the simple fact that they hold, that the truth is to be found only in this kind of history. They feel that it is not necessary for them to dwell on their own sincerity in their writings - they are already known to and praised by the rationalists as fighting under the same banner, and they not only plume themselves on these encomiums, which are a kind of salary to them but would only provoke nausea in a real Catholic, but use them as an offset to the reprimands of the Church. But let us see how the Modernist conducts his apologetics. The aim he sets before himself is to make the non-believer attain that experience of the Catholic religion which, according to the system, is the basis of faith. There are two ways open to him, the objective and the subjective . The first of them proceeds from agnosticism. It tends to show that religion, and especially the Catholic religion, is endowed with such vitality as to compel every psychologist and historian of good faith to recognise that its history hides some unknown element. To this end it is necessary to prove that this religion, as it exists today, is that which was founded by Jesus Christ; that is to say, that it is the product of the progressive development of the germ which He brought into the world. Hence it is imperative first of all to establish what this germ was, and this the Modernist claims to be able to do by the following formula: Christ announced the coming of the kingdom of God, which was to be realised within a brief lapse of time and of which He was to become the Messiah, the divinely-given agent and ordainer. Then it must be shown how this germ, always immanent and permanent in the bosom of the Church, has gone on slowly developing in the course of history, adapting itself successively to the different mediums through which it has passed, borrowing from them by vital assimilation all the dogmatic, cultural, ecclesiastical forms that served its purpose; whilst, on the other hand , it surmounted all obstacles, vanquished all enemies, and survived all assaults and all combats. Anybody who well and duly considers this mass of obstacles, adversaries, attacks, combats, and the vitality and fecundity which the Church has shown throughout them all, must admit that if the laws of evolution are visible in her life they fail to explain the whole of her history - the unknown rises forth from it and presents itself before us. Thus do they argue, never suspecting that their determination of the primitive germ is an a priori of agnostic and evolutionist philosophy, and that the formula of it has been gratuitously invented for the sake of buttressing their position.
