Perhaps you should brush up on your knowledge of the manner by which the Church assigns a particular theological note to a particular teaching. Moreover, any teaching which contradicts a prior dogmatic pronouncement is ipso fact null and void. QUANTA CURA clearly meets all the criteria for dogmatic teaching. An ecumenical counsel is NOT dogmatic where the VERY POPE WHO PRESIDES OVER IT DECLARES TO THE CONTRARY. HIs successors also noted the Council's "pastoral" nature".
