This is the very definition of Modernism:
You take a Catholic definition of dogma, apply some distinction and tortured logic, stir it all up, and then proclaim that the Church believes nearly the exact OPPOSITE of what the dogma actually taught.
For 1600 years, the entire Church taught and believed that there could be no salvation without knowledge of and belief in Jesus Christ and the Holy Trinity.
Shortly before 1600, a handful of Jesuits, responding to the discovery of the New World, and echoing Fr. Cekada's sentiments that they could simply not believe that all those people had been lost (so doing emotion-based "theology") ... invented "Rewarder God" theory.
deLugo, also a Jesuit, picked up on this.
XavierSem cited deLugo as teaching: "... Turks and ... Moslems, as well as the Jews, ... [and] most heretics ... can be saved."
This is a word-for-word denial of the solemn dogmatic teaching of the Council of Florence: "[The Church] firmly believes, professes, and proclaims that ... pagans, ... Jews and heretics and schismatics cannot become participants in eternal life, but will depart “into everlasting fire which was prepared for the devil and his angels” [Matt. 25:41], unless before the end of life the same have been added to the flock."
How were they able to overturn Catholic dogma and profess the opposite?
St. Alphonsus explains that it was by applying a "distinction". St. Alphonsus notes that "all the Scriptures and Church Fathers" clearly teach the necessity of explicit belief in Jesus Christ and the Holy Trinity for salvation. But these Jesuit Modernist-heretic innovators claimed that this "necessity" was but a necessity of "precept" and not a necessity of means. So, until the Church explicitly condemned this distinction, they could escape the charge of heresy ... despite being able to use this distinction to word-for-word deny EENS dogma ... as deLugo did.
Evidently, however, and tragically, St. Alphonsus was unaware that the Holy Office in 1703 had condemned the "necessity of precept" distinction as applied to this issue and maintained that explicit knowledge of the central mysteries of the faith were necessary by a "necessity of means" for salvation. So much so that EVEN IN DANGER OF DEATH, Baptism was not permitted without this knowledge. Now the Church has always made concessions for "danger of death" scenarios, where, for instance, doubtful measures can be taken if they're all that are possible ... doubtful Sacraments may in that case and only in that case be received. So by making this statement, the Holy Office was saying "not a chance," this opinion is NOT "probable" as St. Alphonsus declared later, ignorant of this decree from the Holy Office.
When we take that distinction off the table, and as Catholics we MUST, since it was rejected by the Holy Office, and that decision never overturned, we MUST REGARD Rewarder God theory to be heretical, since without said distinction it contradicts "all the Scriptures and Church Fathers".
Here's the Holy Office Decree: "Question: Whether it is possible for a crude and uneducated adult, as it might be with a barbarian, to be baptized, if there were given to him only an understanding of God and some of His attributes, especially His justice in rewarding and punishing, according to the remark of the Apostle ... from which it is to be inferred that a barbarian adult, in a certain case or urgent necessity, can be baptized even though he does not explicitly believe in Jesus Christ. Response: A missionary should not baptize one who does not explicitly believe in the Lord Jesus Christ but is bound to instruct him about all those matters which are necessary, by a necessity of means, in accordance with the capacity of the one to be baptized."
So, after about 100 years of churn on the "Rewarder God" theory, despite the Holy Office condemnation, we have people like deLugo using this distinction to word-for-word contradict Catholic dogma.
THIS IS THE VERY DEFINITION OF MODERNISM ... to take tortured logic and false distinctions to cause the meanings of Catholic dogma to change, even to the point of claiming that they mean the very opposite of what they actually say.
If Catholics may do this to EENS dogma, then why couldn't Pius IX's condemnation of Religious Liberty really NOT apply to what Vatican II taught? After all, if you can go from saying that infidels cannot be saved to saying that infidels CAN be saved, what Catholic dogma is safe?
In addition, this heresy that non-Catholics can be saved is at the very heart of EVERY SINGLE VATICAN II "ERROR". Catholics who believe that non-Catholics can be save don't have a leg to stand on in rejecting Vatican II, and so are basically in objective schism. If non-Catholics can be saved, then, since there's no salvation outside the Church, it necessarily follows that non-Catholics can be in the Church, so Vatican II subsistence ecclesiology is right on the money.
