Really? Here is Boniface VIII... "There is one holy Catholic and apostolic church, outside of which there is no salvation...it is altogether necessary for salvation for every creature to be subject to the Roman Pontiff." Unam Sanctum 1302AD.
Sounds a little more serious than you have claimed. And, Boniface is a major contributor to Catholic Law, my FRiend.
But, if you wish to head this direction, into the light of Jesus alone, then swim the Tiber the other direction and leave the Roman traditions, rituals, ceremonies and errant doctrines and we stand ready to welcome you...if Jesus permits. We are praying for you folks.
The Catholic belief is that all salvation comes through the Catholic church. This may include graces obtained by Protestants and others through the working of the Catholic church, despite their separation from the Catholic church.
The valid reception of the sacraments, including sincere and penitential reception of the Sacrament of Reconciliation (”confession”) preceding the Sacrament of the Eucharist (”communion”) is the ordinary means by which a soul may know it is in the state of grace. Orthodox churches likely possess valid sacraments, despite the state of schism, so that their communicants are saved through those sacraments; Protestant churches do not possess valid sacraments. Nonetheless, a Protestant may be saved through a sacrament of desire. That is, though the Protestant offering of bread and wine is not transubstantiated into the body of Christ, the person who genuinely and sincerely desires to receive the body of Christ has hope of doing so. (The Baptism of Desire is the means, for instance, of the salvation of St. Dismas, the good thief on the cross with Jesus.)
Some people detect a contradiction between the Council of Trent, which anathematizes all Protestants, and the Second Vatican Council, which hopes for their salvation through the extraordinary means mentioned above. There is, however, no contradiction. As used in the Council of Trent, “Protestant” referred to people who had been baptized, catechized (educated), and raised as Catholics and yet rejected the Catholic faith to take cause with those who sought the abolition of the Catholic church. Today, “Protestants” may include those who were raised by parents seeking God, have become “invinceably ignorant” by the reception of false doctrines, and who honor their mother and father by persisting in the Christian faith as they know it.
