Why does Vatican Council II have to mention being saved in invincible ignorance and implicit desire(AG 7, LG 14) with reference to all needing faith and baptism for salvation(AG 7, LG 14)? It was a mistake.

From the blog The Eponymous Flower : True or False Pope Part I: John Salza

This text also designates as THE instrumental cause of justification the Sacrament of Baptism - not a "desire" to receive it. Therefore, the reception of the Sacrament of Baptism, which is the “Sacrament of Faith”, is the ONLY instrumental means by which man was ever justified. Therefore, there is no justification without the reception of the Sacrament of Baptism, which is administered with water.
Lionel:
Donnacha, I agree with you.
However would you also agree that there are NO objective cases of the baptism of desire in the present times or in the past?
So the baptism of desire is not relevant to EENS. The Letter of the Holy Office made an objective mistake and the same irrational conclusion was placed in Vatican Council II (AG 7, LG 14) ?

It was a mistake. The Council Fathers assumed these cases were relevant and exceptions to EENS, so they included this error in the text of Vatican Council II.-Lionel Andrades
