It really does seem to be pride. Just look at how every authoritative Catholic source, including the Catholic Encyclopedia, understood the condemnations of Baius, before the "enlightened" Dimonds came forward to correct all the Popes, Saints, Doctors and Theologians. [By the way, anyone knows who wrote "De Rebaptismate mentioned in the CE? There's a Fifth Ancient Source right there]
From:
https://www.newadvent.org/cathen/02258b.htm"The baptism of desireThe baptism of desire (baptismus flaminis) is a perfect contrition of heart, and every act of perfect charity or pure love of God which contains, at least implicitly, a desire (votum) of baptism. The Latin word flamen is used because Flamen is a name for the
Holy Ghost, Whose special office it is to move the heart to
love God and to conceive penitence for
sin. The "baptism of the
Holy Ghost" is a term employed in the third century by the αnσnymσus author of the book "De Rebaptismate". The efficacy of this baptism of desire to supply the place of the baptism of water, as to its principal effect, is
proved from the words of
Christ. After He had declared the
necessity of baptism (
John 3), He
promised justifying grace for acts of charity or perfect
contrition (
John 14): "He that
loveth Me, shall be
loved of my Father: and I will
love him and will manifest myself to him." And again: "If any one
love me, he will keep my word, and my Father will
love him, and we will come to him, and will make our abode with him." Since these texts declare that
justifying grace is bestowed on account of acts of perfect charity or
contrition, it is evident that these acts supply the place of baptism as to its principal effect, the remission of
sins. This
doctrine is set forth clearly by the
Council of Trent. In the fourteenth session (cap. iv) the council teaches that
contrition is sometimes perfected by charity, and reconciles
man to
God, before the
Sacrament of Penance is received. In the fourth chapter of the sixth session, in speaking of the
necessity of baptism, it says that
men can not obtain original justice "except by the washing of
regeneration or its desire" (voto).
The same doctrine is taught by Pope Innocent III (cap. Debitum, iv, De Bapt.), and the contrary propositions are condemned by Popes Pius V and Gregory XII, in proscribing the 31st and 33rd propositions of Baius."Let no one say the Catholic Encyclopedia doesn't define what Trent means by Baptism of Desire either, because it clearly does above.
