No one knows of any one saved outside the visible boundaries of the Catholic Church. This is an objective mistake made in the Letter of the Holy Office 1949.

Presenters Tell Us ?

'outside the visible boundaries of the Catholic Church.'

Lionel:

No one knows of any one saved outside the
 visible boundaries of the Catholic Church. This
 is an objective mistake made in the Letter of 
the Holy Office 1949.

Physically no one in 1949 could have seen 
a case of someone saved outside the visible
 boundaries of the Church, i.e without faith
 and baptism.

Cardinal Schonborn must be told that

 there are no known cases of someone 

saved outside the Church
