Modernism thrives on vague and ambiguous expressions, on lack of precision, on lack of clear definitions, because Modernism, being sinister, detests clarity, which is one of the hallmarks of truth and orthodoxy: “For every one that doth evil hateth the light, and cometh not to the light, that his works may not be reproved” (John 3:20).
Modernism seeks to make what is certain, doubtful, what is clear, confusing; it tries to make the straight paths of True Catholicism crooked, and so becomes the anti-Gospel.”
