Well, why don’t YOU tell me. And then I can give you multiple official pronouncements by past popes to contradict your fantasies.
You are the one asking the question. In trying to come up with an answer, I searched the Catechism of the Catholic Church, which is a full, complete exposition of Catholic doctrine. I did not find where it says that Catholic doctrine contradicts the idea that “Protestant Christians can be saved and are genuine Christians.”
So you tell me. Where does it say in the Catechism that Protestant Christians cannot be saved and are not geniune Christians?
As we can see; OP's mean NOTHING if they cannot be claimed to be INFALLIBLE.
