Common Arguments
 
1.  The Council of Trent did not speak about Baptism of Desire.

Some have tried to argue that the Council of Trent did not speak of Baptism of Desire, so as to try and remove the only example of solemn teaching on the subject, leaving all other examples above as ordinary teaching. First, you'll notice in the quotes above that St. Robert Bellarmine states, "...the Council of Trent, Session 6, Chapter 4, says that Baptism is necessary in fact or in desire". St. Alphonsus Liguori also states above, "Now it is "de fide" that men are also saved by Baptism of desire, by virtue of the Canon Apostolicam, "de presbytero non baptizato" and of the Council of Trent, session 6, Chapter 4...". The quote from the Catholic Encyclopedia above also states, “This doctrine (baptism of desire) is set forth clearly by the Council of Trent". And the quote from the Letter of the Holy Office above also states, "This (Sacrament through desire) we see clearly stated in the Sacred Council of Trent..." So it is obvious the Holy Office, these two Doctors of the Church, and the Catholic Encyclopedia state otherwise. As for those who try to discredit the Catholic Encyclopedia; over 1500 clergy, professors, authors etc. from around the world contributed to its compilation, in addition to it containing an imprimatur, so it is considered a trusted Catholic reference.

Regardless of these facts, we can clearly see from the definitions of the Magisterium above, that whether the Council of Trent spoke of this doctrine or not is irrelevant, since we can see the Ordinary magisterium (also infallible) has also taught it repeatedly century after century.

Trent teaches there is no spiritual regeneration without water.  Desire alone is faith alone, a notion that belongs in hell with Luther.
