One of the modernist tricks, after all, is to cite preconciliar sources to urge conformity to postconciliar doctrines that would have sent those sources climbing up a wall. Modernists in particular like to cite Pius X or Pius XII--in support of novelties that would have horrified them.
At the same time the very people who do this, trash Trent and the Syllabus of Errors and whatever else preconciliar popes supported. It only works one way, apparently. The New Religion feels no compulsion to honor the past in any way--except when necessary to bring ordinary Catholics into strict obedience with its own false agenda.
Are you accusing me of this?
