Francis Wrong Again: Amoris Laetitia Is Anything But Thomistic

Pope Francis and Cardinal Burke have made an in principle mistake in faith and morals since we cannot judge exceptions to the general rule on mortal sin and exclusive salvation.
MORALS/MORTAL SIN
We cannot say that any particular couple who is living in concubinage is living as a brother and sister. This is something only God can know.
We cannot tell a couple who are divorced and remarried that they are not in mortal sin since they are following their conscience.
In principle we cannot physically know of any exception to the general teaching on mortal sin.

SALVATION/FAITH
Similarly we cannot say that every one in the USA or Italy does not need to be a member of the Catholic Church since there could be exceptions of the baptism of desire and blood and being saved in invincible ignorance.None of us can know of someone who will be saved or is saved outside the Church in invincible ignorance etc and without the baptism of water. So there can be no physical exceptions known to us to the dogma extra ecclesiam nulla salus which says every one needs to be incorporated into the Church as a member to avoid Hell ( for salvation).

However for the two popes and Cardinal Burke ( and all the other cardinals) in principle what is unknown is known, in principle what is physically invisible is visible, in principle what is only known to God in Heaven is also known in personal cases to us human beings on earth. This is philosophical cheating.
No where does St. Thomas Aquinas state that we know of people who are going to be saved in mortal sin. There could be diverse cases and different situations but only God can say that someone will be an exception and will not be going to Hell.
