Call it what one will…Modernism, Liberalism, hard left, reformers…
Consider that the Church has enemies not just OUTSIDE, but moreso INSIDE and professing to be Catholic.

[**Encyclical by Pope Saint**]("http://www.dailycatholic.org/pascend1.htm") Pius X on Modernism given on September 8, 1907 Articles 2-3
2. That We should act without delay in this matter is made imperative especially by the fact that the partisans of error are to be sought not only among the Church’s open enemies; but, what is to be most dreaded and deplored, in her very bosom, and are the more mischievous the less they keep in the open. We allude, Venerable Brethren, to many who belong to the Catholic laity, and, what is much more sad, to the ranks of the priesthood itself, who, animated by a false zeal for the Church, lacking the solid safeguards of philosophy and theology, nay more, thoroughly imbued with the poisonous doctrines taught by the enemies of the Church, and lost to all sense of modesty, put themselves forward as reformers of the Church; and, forming more boldly into line of attack, assail all that is most sacred in the work of Christ, not sparing even the Person of the Divine Redeemer, whom, with sacrilegious audacity, they degrade to the condition of a simple and ordinary man.
3. Although they express their astonishment that We should number them amongst the enemies of the Church, no one will be reasonably surprised that We should do so, if, leaving out of account the internal disposition of the soul, of which God alone is the Judge, he considers their tenets, their manner of speech, and their action. Nor indeed would he be wrong in regarding them as the most pernicious of all the adversaries of the Church. For, as We have said, they put into operation their designs for her undoing, not from without but from within. 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 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, so that there is no part of Catholic truth which they leave untouched, none that they do not strive to corrupt.
