It's offensive when a university implies Catholics can see the dead or that human beings in general can see the dead.
Catholics in general cannot see the dead!
It's offensive when a university implies there is some magisterial text which states Catholics can see the dead on earth. There is none.
It's offensive when a university promotional video does not tell the truth which is - Vatican Council II affirms, endorses, agrees with the dogma extra ecclesiam nulla salus as it was interpreted throughout the centuries.There are no visible exceptions to the Catholic traditional teaching on other religions and Christian communities and churches.
If Vatican Council II and the Catechism of the Catholic Church do not contradict the dogma extra ecclesiam nulla salus there is no change in the Catholic Church's teaching, as implied by the University of Bristol.
