So if the 7 sacraments got handed down from the Apostles why did it take to the COT to make it official? That’s fifteen hundred years after the fact. It was also established at COT that the 7 sacraments are needed for salvation and that Grace isn’t enough.
The Council of Trent did NOT “make it official” for the first time. The CoT restated the Church’s teaching because it was being denied by the Protestants.
Teh Council of Trent also said that Jesus rose from the dead. Are you going to argue that it took the Catholic Church 1500 years to “invent” the Resurrection?
Many anti-Catholic propagandists make the same blunder: They find an instance where the Church’s teaching is restated, and they proclaim that THAT is the moment when the teaching was “invented.”
