I, for one, am never comfortable with such men preaching their "theology". St. Pius X said the most dangerous Modernists are those that are in the church: (Pascendi)
"Through pride the Modernists overestimate themselves. . . . We are not like other men . . . they reject all submission to authority . . . they pose as reformers."
3. "...Hence, the danger is present almost in the very veins and heart of the Church, whose injury is the more certain from the very fact that their [the Modernists] knowledge of her is more intimate. Moreover, they lay the ax not to the branches and shoots, but to the very root, that is, to the faith and its deepest fibers. And once having struck at this root of immortality, they proceed to diffuse poison through the whole tree..."
50. "It is also the duty of the Bishops to prevent writings of Modernists, or whatever savors of Modernism or promotes it, from being read when they have been published, and to hinder their publication when they have not. No books or papers or periodicals whatever of this kind are to be permitted to seminarists or university students. The injury to them would be not less than that which is caused by immoral reading-- nay, it would be greater, for such writings poison Christian life at its very fount. The same decision is to be taken concerning the writings of some Catholics, who, though not evilly disposed themselves, are ill-instructed in theological studies and imbued with modern philosophy, and strive to make this harmonize with the faith, and, as they say, to turn it to the profit of the faith. The name and reputation of these authors cause them to read without suspicion, and they are, therefore, all the more dangerous in gradually preparing the way for Modernism."
Believe me, I agree. I'm just saying these perfidious morons have also sown the seeds of their own destruction. They're headed the way of the Arians et al.
