So, the Council of Florence got it wrong, then, Hollingsworth, "The Most Holy Roman Church firmly believes, professes, and proclaims that those not living within the Catholic Church, not only pagans, but also 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; and that the unity of the ecclesiastical body is so strong that only to those remaining in it are the sacraments of the Church of benefit for salvation, and do fastings, almsgiving, and other functions of piety and exercises of Christian service produce eternal reward, and that no one, whatever almsgiving he has practiced, even if he has shed blood for the name of Christ, can be saved, unless he has remained in the bosom and unity of the Catholic Church."
Do you not know what St. Theresa said about Luther and Calvin, how their false presumption deceived them and led them to hell?
Also, there was a mystic to whom Our Lady used to appear. And in those days when every Catholic used to believe heretics must become Catholics to be saved, when asked by Protestants, "Can we Protestants be saved?" She gave a non-committal answer, like most Catholics today would give, "I can't judge that". But Our Lady said, "My daughter, since you had too much human respect, I won't appear to you again". And She did not. Catholics, when asked, should say you must be Catholic to be saved. Pope St. Pius X authorized the Holy Office decree that taught, "Catholic, when interrogated, should answer that those who die as infidels are damned."
St. Alphonsus always preached heretics and infidels who died in final impenitence were lost. Oh !what an invaluable benefit is the gift of faith ! How many millions of souls, among infidels and heretics, are deprived of the Sacraments, of sermons, of good example,and of the other helps to salvation which we possess in the true Church."
Edit: Jayne, the person who voted Protestants for the first option probably disagrees with you. Protestants, as Protestants, can't be saved. What St. Alphonsus says of infidels, “Still we answer the Semipelagians, and say, that infidels who arrive at the use of reason, and are not converted to the Faith, cannot be excused ... if the infidel cooperates with this movement, observing the precepts of the law of nature, and abstaining from grievous sins, he will certainly receive, through the merits of Jesus Christ, the grace proximately sufficient to embrace the Faith, and save his soul.” applies in the same way to heretics. To be saved, Jesus requires of Protestants what the Church does - to renounce pagan and Protestant errors, and ask to receive the gift of Catholic Faith, and salvation.
