"Baptism of spirit (flaminis), which is also called of repentance or of desire is nothing else than an act of charity or perfect contrition includeing a desire of the Sacrament, according to what has been said above, namely that, the heart of everyone is moved by the Holy Ghost to believe, and to love God, and to be sorry for his sins." - De Ecclesiae Sacramentis (Vol. I); Quaestio LXVI; Thesis XXIV - 1931
I don't care how many theologians you quote, you can quote two thousands theologians still they can only speculate and propose their conclusions. They can't define what the Church never defined
You'll die without knowing of Baptism of Desire works the way theologians have proposed because it's a teaching of man and not a teaching of the Church. The only is certain is:
Only One Baptism, Only Water Baptism.So you can quote 2000 theologians for what I care.
