So what does a Catholic do when the present two popes are in sin? Simple.Don't follow their errors( heresy) in faith and morals.The teachings of the Church do not change. Jesus is the same yesterday, today and tomorrow. Read the Catholic classics. Follow them.Even if a pope in public sin considers sin 'ideology', 'rigidness' and a lack of openness to whatever - don't follow him in sin. Popes can go to Hell. So they go for Confession, too.

Pope Francis and Pope Benedict are in mortal sins of faith.Also with their moral theology they have confused the concept of mortal sins, for Catholics in general.

The two popes change the understanding of the Nicene Creed and reject the Athanasius Creed  with their irrational interpretation of the baptism of desire(BOD), baptism of blood(BOB) and invincible ignorance(I.I).

They also confuse the concept of mortal sin.They have a confusing concept of the three conditions for mortal sin mentioned in the Catechism of the Catholic Church.The same confusion is there in Pope Francis', Amoris Laetitia.

A mortal sin is a mortal sin says Pope John Paul II's encyclical Veritatis Splendor.The external act indicates the inner subjective motivation.
The new moral theology says that the external act does not indicate the subjective understanding. It's the opposite.

We can judge that a person dressed vulgar is in a mortal sin and so we do not give the Eucharist  to him and her.

The new moral theology, approved by the two popes and the Left,  say we cannot judge externally when someone is in mortal sin, even when we can see it and so the Eucharist is given.

The Amazon Synod will approve a mortal sin when it will decide that the Eucharist is only a symbol, a sign, a meal and so all can receive it.
Even salvation theology has been changed.Vatican Council II says all need faith and baptism for salvation(AG 7). The present two popes say 'no'.There are exceptions.

This is a rejection of the old ecclesiology of the Church based on John 3:5 and Mark 16:16. This is a rejection of the faith-teaching by the two popes. It is heresy and it is schism with the past popes over the centuries.
A mortal sin in morals is a mortal sin and the three conditions can and will be judged only by God.
A mortal sin of faith e.g not choosing to be Catholic is a mortal sin and the exceptions will only be known to God.
The norm for salvation is Catholic faith and the baptism of water. It is not other religions. So the Abu Dhabi declaration and its follow up is heresy and schism for the present two popes.
The present two popes do not affirm BOD, BOB and I.I and LG 8, LG 14, LG 16, UR 3, NA 2, GS 22 etc rationally.Otherwise Vatican Council II  would support the past exclusivist ecclesiology and an ecumenism of return.Again, this is heresy on their part.They are denying the faith. This was an error of the popes since Paul VI, who interpreted the Council only with the irrational premise.Hypothetical cases are objective people in the present times for them. LG 8, LG 16 etc refer to personally known non Catholics saved outside the Church...
