J. Paul, there are many examples of souls saved by Baptism of Desire and Blood throughout Christian history. To limit ourselves only to the Apostolic age, Sts. Emerentiana and Victor of Braga were saved by means of the Baptism of Blood, as Tradition informs us and was always believed before Fr. Feeney, and Valentian and Herais were saved by means of the Baptism of Desire, as Tradition informs us and was, again, always believed before the 20th century.
The Popes have irreformably approved the teaching that "souls are saved Baptism of Desire" which St. Alphonsus bases on Trent and on Innocent II, and this latter letter tells us of a soul saved by Baptism of Desire. So it is not right to say what Fr. Feeeney mistakenly - and surely in good faith - said, and Catholics must not say it anymore, but hold to the traditional understanding on this point.
Saints like Catherine of Sienna, Therese Liseux, Padre Pio, John Vianney and countless others all bear witness, by special revelation made to them by the Lord or His Mother, that souls were saved by means of the Baptism of Desire.
"I wished thee to see the secret of the Heart, showing it to thee open, so that you mightest see how much more I loved than I could show thee by finite pain. I poured from it Blood and Water, to show thee the baptism of water which is received in virtue of the Blood. I also showed the baptism of love in two ways, first in those who are baptized in their blood shed for Me which has virtue through My Blood, even if they have not been able to have Holy Baptism, and also those who are baptized in fire, not being able to have Holy Baptism, but desiring it with the affection of love. There is no baptism of desire without the Blood, because Blood is steeped in and kneaded with the fire of Divine charity, because through love was it shed.
I honestly cannot understand how someone can read the Savior Himself explain the reason He poured out Blood and Water from His own Sacred Heart with such precision and doctrinal exactitude and then refuse to believe Him. Anyway, many of the Fathers of the Church, commenting on this passage in the Gospel of St. John, see revealed therein the Baptism of Water and of Blood. Many Doctors and other authorities see in the epistle of St. John the doctrine that baptism is triune - in water, in the blood and in the Spirit - just as God Himself is Triune and not a monad, 1 Jn 5:5Who is he that overcometh the world, but he that believeth that Jesus is the Son of God? 6This is he that came by water and blood, Jesus Christ: not by water only, but by water and blood. And it is the Spirit which testifieth, that Christ is the truth. 7And there are three who give testimony in heaven, the Father, the Word, and the Holy Ghost. And these three are one. 8And there are three that give testimony on earth: the spirit, and the water, and the blood: and these three are one. " St. Thomas in particular discourses in this sense.
Cantarella, yes, the Dimonds claim that the doctrine "souls are saved by Baptism of Desire" is a heresy and they claim their heresy is dogma. You are also correct Cornelius is an example of justification by Baptism of Desire. I understand the SBC is much better, they do not believe it is a heresy, however, they are also incorrect to think it is only an opinion. No, it is a doctrine we must accept as we accept any other, for example, perfect contrition or spiritual communion.
Ironically, Director's post above contains a good summary of why the "justification but not salvation" view is untenable. I mentioned some of the reasons above, and if only a dogmatic definition will satisfy you.
Pope Paul III, Council of Trent, Sess. 6, Chap. 16: “… hence IT MUST BE BELIEVED THAT NOTHING MORE IS NEEDED FOR THE JUSTIFIED TO BE CONSIDERED TO HAVE FULLY SATISFIED THE DIVINE LAW, according to this state in life, by the deeds they have wrought in him and to have truly merited eternal life to be obtained in its own time (if they shall have departed this life in grace)…”
It is de fide that nothing else is necesary for the justified to be saved other than perseverance in the grace and justice received, in other words, justification is the translation to the state of grace, perseverance is dying in the state of grace, and this passage in Trent says it must be believed that the justified are heirs to eternal life and considered to have fully satisfied the divine law and will certainly inherit eternal life if they but die in the state of grace. So if not heretical, it is at least next door to heresy, to say that this is insufficient but that something else is necessary.
