Your post reveals a COMPLETE ignorance on how dogma is affirmed. G.K>. Chesterton characterized the development of Catholic teaching to a run-away cart racing down a mountain road. The Church declares only to correct like the cart striking the rock or the rails. In each of the instances you cited, the Church did not introduce a new teaching, it only affirmed the correct one when confronted with error.
The thing that differentiates Catholic teaching is that it harmonizes the ENTIRE Old and New Testaments with the entire Sacred Tradition. All heresies are established not by what they affirm, but by what they deny or ignore.
Peace be with you
