It is quite sad. Hopefully in some instances the "Father, forgive them, for they know not what they do." will come into play.
Hopefully there are some sincere people out their with a supernatural Faith who really will to do God's will and love Him more than anything else. Hopefully some people who commit mortal sins in the objective realm are ignorant of this fact through no fault of their own.
One thing I do is count the number of traditional Catholics in my city and think, that is the amount of people in my city who have a good chance to be saved. So in my city there are maybe a thousand traditional Catholics (based on Mass attendance) so that means about one in every five thousand people or so has a good chance to be saved.
(Not counting those who die before the use of reason)
Right. Only true Catholics have a good chance to be saved and many of us are in trouble. If many of us saw our souls as God sees them we might die of fright. It is a scary thing to consider.
Many people also know when they commit a mortal sin even if in their mind they think of it as "doing something wrong". They feel the guilt pang the first time they do it as God has written the law on our hearts. Many people claim to love our Lord but do not and will not be saved.
Sadly there are some who partake of the outer bonds of dis-unity with heretical Church's whose lives appear to put some traditional Catholics to shame whether they partake of the inner bonds of unity within the Mystical Body of Christ or not. Despite the fact that they could be within the Church by desire because of a supernatural Faith and perfect charity it appears to be far more likely, generally speaking that many or most of them could in regards to their apparent charity towards one another have only a natural charity not rooted in the love of God above all things.
There are others who grew up Catholic and by all appearances have rejected the Faith such as Mother Theresa and all the false Popes and they are in much worse shape than those, who through no fault of their own, never had the Faith to begin with. It is said to think that by all appearances that Mother Theresa is damned as in the natural realm she put most, if not all to us to shame in regards to all the natural good she did. But that is the reality of it.
