For these reasons the Teaching Authority of the Church does not forbid that, in conformity with the present state of human sciences and sacred theology, research and discussions, on the part of men experienced in both fields, take place with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter - for the Catholic faith obliges us to hold that souls are immediately created by God. (Pius XII, Humani Generis, 36)
18. Love (in reference to God,
I've discovered another Modernist! "He that loveth not knoweth not God: for God is charity" (1 St. John 4:8).
22. (active) participation
I find it amusing that he then appeals to St. Pius X's intercession, since St. Pius X called for active participation.
We deem it necessary to provide before anything else for the sanctity and dignity of the temple, in which the faithful assemble for no other object than that of acquiring this spirit from its foremost and indispensable font, which is the active participation in the most holy mysteries and in the public and solemn prayer of the Church. (St. Pius X, Tra le Sollecitudini)
Yes, there are orthodox interpretations of these very words. The point is that usually the modernist means something else entirely by them. And in Humani Generis, just because Pius XII said a certain view of evolution was not necessarily contradictory to the Faith, does not mean he endorsed it. Also, the modernists employs this term frequently to all kinds of situations within the Church (liturgy) and means something else totally by it--as if it was "common knowledge" that everything evolves.
The Latin word for "active" is not used in Sacrosactum Concilium. I doubt it was used in the Pius X encyclical you quote either. Regardless, "active" participation for some people can mean silently meditating or comtemplating the Sacred Mysteries OR simply contemplating Christ's life through use of the rosary.
As for love, the modernist usually means "a good feeling or sentiment," not St. Thomas's definition of charity.
