Um, I never heard Pope Innocent III nor Pope Eugene IV; as in listened to them speak.

Have you never heard any faithful priest reiterate this infallibly defined doctrine?

Please notice that these citations you give were made before there was any other Church.

There is still only one Church. Other groups that call themselves Christians are not technically churches.

All Catholics (or Christians), before the Great Enlightenment, believed that the Church was the body of Christ,

There were heretics and schismatics before the enlightenment. Infallibly defined doctrine by definition cannot change, it is true for all time.

Only as I have cited above. Have you ever heard a faithful priest say that those who have never been exposed to Catholic teaching cannot be saved? That was the nature of my first post to William Terrell.
