Emeraldlady,
Yes, that is correct there have been Two Thousands years of Church teaching.
It seems that some want to accept the latest novelties and reject the constant and clear teachings of the past Popes, Councils, and Magisterial teachings.
As Pope St. Pius X put it "But for Catholics nothing will remove the authority of the second Council of Nicea, where it condemns those ‘who dare, after the impious fashion of heretics, to deride the ecclesiastical traditions, to invent novelties of some kind . . . or endeavor by malice or craft to overthrow any one of the legitimate traditions of the Catholic Church’. . . . Wherefore the Roman Pontiffs, Pius IV and Pius IX, ordered the insertion in the profession of faith of the following declaration: ‘I most firmly admit and embrace the apostolic and ecclesiastical traditions and other observances and constitutions of the Church’.” - - Encyclical Against Modernism (Pascendi).
