"These latter days have witnessed a notable increase in the number of the enemies of the Cross of Christ, who, by arts entirely new and full of deceit, are striving to destroy the vital energy of the Church, and, as far as in them lies, utterly to subvert the very Kingdom of Christ. Wherefore, We may no longer keep silence, lest We should seem to fail in Our most sacred duty, and lest the kindness that, in the hope of wiser counsels, We have hitherto shown them, should be set down to lack of diligence in the discharge of Our Office" (Pope Saint Pius X, Giuseppe Sarto [Tuesday, August 4, 1903 - Thursday, August 20, 1914], Encyclical Pascendi Dominici Gregis, On the Doctrine of the Modernists -  Sunday, September 8, 1907).
