Salvation is not dependent on a certain level of intellect. There are millions of mentally handicapped persons who would be denied even the desire of Baptism. .
Agreed. “…those who are affected by ignorance of the true religion, if it is invincible ignorance, are not subject to any guilt in this matter ” [Pope Pius IX]. A severely mentally handicapped person would qualify as invincibly ignorant. Scripture and the Church teach the viability of infant baptism based on inheriting the faith of the family and their desire for baptism for their child. I think this would also apply to mentally handicapped persons being baptized later on in life.
. As for those who are unaware of the Gospel or the understanding of the Incarnation, or the Trinity (which isn´t even the requirement, but assent of faith regarding them), they cannot be held responsible for rejecting it. .
Certainly, if they are unaware of the Gospel, through invincible ignorance, they are not held responsible for this ignorance! That is the teaching of Pope Pius IX, discussed in previous posts, on which, I think, we all agree.
But, nor does invincible ignorance save, or else, what would be the point of missionary work? St. Thomas Aquinas explains that the unbaptized invincibly ignorant are not held responsible for not knowing the Faith, but they will die in their other sins.
“Therefore, I said to you, that you shall die in your sins: for if you believe not that I am he, you shall die in your sin.” (John 8:23-24)
I’m not sure exactly what you mean by “which isn´t even the requirement, but assent of faith regarding them”, but explicit faith in a few elemental doctrines are required as “a necessity of means” for the Sacraments to be effective in remitting sin:
Pope Benedict XIV, *Cum Religiosi{/I] (# 1), June 26, 1754:
“We could not rejoice, however, when it was subsequently reported to Us that in the course of religious instruction preparatory to Confession and Holy Communion, it was very often found that these people were ignorant of the mysteries of the faith, even those matters which must be known
by necessity of means; consequently they were
ineligible to partake of the Sacraments.”
St. Thomas Aquinas,
Summa Theologica: “After grace had been revealed,** both the learned and simple folk are bound to explicit faith in the mysteries of Christ**, chiefly as regards those which are observed throughout the Church, and publicly proclaimed, such as the articles which refer to
the Incarnation, of which we have spoken above.”
And from the “Apostle of Love”:
John 3:16:“For God so loved the world, as to give His only begotten Son:*** that whosoever believeth in Him***, may not perish, but may have life everlasting.”
John 3:36: “
He that believeth in the Son hath life everlasting: but he that believeth not the Son, shall not see life, but the wrath of God abideth on him.”
And as for Unam Sanctam (and this is my small and limited knowledge on the document), there is much to be taken into consideration. It is a pre reformation document and is more about the political relationship with the secular powers and the Church. It is to those who think that earthly power is above all. It was not intended to pertain to various Christians in an imperfect communion, which do have the saving Gospel given to the one Church.
How can you say " It was not intended to pertain to various Christians in an imperfect communion,…"?
Quoting again from Unam Santam (post 341): “we declare, say, define, and proclaim to every human creature that they by absolute necessity for salvation are entirely subject to the Roman Pontiff.”
So, do you believe that Christians “in imperfect communion” are not human creatures?*
