Canon 4 refers to, as you even quoted yourself, Sacraments in general. Ergo for that canon to prove desire for Baptism can replace Baptism, then Matrimony of Desire or Holy Orders of Desire must also be doctrines according to your twisted logic. So your canon cannot be proof for Baptism of Desire. All it proves is that SOME Sacraments can be received in desire, namely Reconciliation. Trent explains Reconciliation can be received in desire in other canons while also explicitly stating that the waters of Baptism cannot be metaphorical. Ergo, your canon does not prove Baptism of Desire and Trent does not support it in any way(and in fact refutes it, as BOD requires metaphorical water).

The answer is no.

The_Holy_Gospel_of_Jesus_Christ,_According_to_St._John
This is explained by the Church in the quotes I provided.  To "enter into the kingdom of God" a man must "be born again of water and the Holy Ghost", which is the sacrament of Baptism.  Should the man be forestalled from receiving the sacrament of Baptism by an untimely death, as Saint Thomas Aquinas explained, "such a man can obtain salvation without being actually baptized, on account of his desire for Baptism," because "God, Whose power is not yet tied to visible sacraments, sanctifies man inwardly."

18. Is judged already: He that believeth in Christ with Faith which worketh by charity (as the Apostle speaketh) shall not be condemned at the later day nor at the hour of his death. But the Infidel, be he Jew, Pagan, or Heretic, is already (if he die in his incredulity) by his own profession and sentence condemned, and shall not come to judgement either particular or general, to be discussed according to his works of mercy done or omitted. In which sense St. Paul saith that the obstinate heretic is condemned by his own judgement, preventing in himself, of his own free will, the sentence both of Christ and of the Church.  

If you notice, right after this paragraph on Baptism, on the very same page, we find the timeless teaching of the Church that every Infidel, Jew, Pagan or Heretic, is judged already".

"...the sacrament of Baptism may be wanting to anyone in reality but not in desire:  for instance, when a man wishes to be baptized, but by some ill-chance he is forestalled by death before receiving Baptism.  And such a man can obtain salvation without being actually baptized, on account of his desire for Baptism, which desire is the outcome of faith that worketh by charity, whereby God, Whose power is not tied to visible sacraments, sanctifies man inwardly."

Dear Mr. JohnAnthonyMarie,

What is the reason for your obsession with teaching people that people can be saved without the sacrament of baptism or belief in Christ and the Incarnation? What bothers you so much about the people who believe that one must be a sacramentally baptized Catholic in a state of grace at death to be saved, that it has become your life's mission to "convert" them?

your The truth, your the accurate information, would (again) be exactly as Saint Thomas Aquinas describes, "...the sacrament of Baptism may be wanting to anyone in reality but not in desire:  for instance, when a man wishes to be baptized, but by some ill-chance he is forestalled by death before receiving Baptism.  And such a man can obtain salvation without being actually baptized, on account of his desire for Baptism, which desire is the outcome of faith that worketh by charity, whereby God, Whose power is not tied to visible sacraments, sanctifies man inwardly."  I would agree that "people can be saved without the sacrament of baptism", but I, myself, could not go so far as saying without "belief in Christ and the Incarnation".  God alone knows.

I asked you if this is what you believe, I do not need to know why you believe it, that is too long and complicated. Please just answer my question:

LT asks: then "your truth, your accurate information", is that people can be saved without the sacrament of baptism or belief in Christ and the Incarnation, that one does not have to be  a sacramentally baptized Catholic in a state of grace to be saved?
