This addresses the question of the disposition of unborn soul … miscarried or murdered in the womb.
We know through sound Catholic teaching that every soul, at the moment of conception is infused with an immortal soul. Thanks to our first parents, our soul is stained with Original Sin.
The only remedy Christ and His Bride, the Holy Roman Catholic Church, has proclaimed, is the remedy of Baptism … form, intention and matter. An unborn soul that is murdered in the womb or is miscarried is denied the Sacrament of Baptism. The soul cannot enter into heaven because it retains Original Sin.
Given that at the end of time, there will be only Heaven or Hell; the soul is relegated to Hell. Some theologians argue that those souls, not guilty of volitional or willful sin, exist in the upper reaches of Hell where there is no pain or torment. They exist in a state of natural happiness … BUT MISS THAT FOR WHICH THEY WERE CREATED … The Beatific Vision.
It is difficult to understand the mystery of God’s infinite Justice … and how it is balanced by His infinite Mercy. However, the divine side of The One Holy Apostolic Catholic Church, guided by the Holy Spirit, gives us direction that is infallibly correct on this issue.
Here are the details:
The Church has made infallible dogmatic statements about the necessity of Baptism. The Church made these infallible statements through various Councils. Also, Popes (speaking from the Chair of Peter or what we would call “ex cathedra”) made infallible proclamations on this subject. In both cases, these statements are infallible dogmatic proclamations that, as Catholics, we must believe. Here are just a few of them:
A. Council of Florence, Decree for the Armenians:
”Holy Baptism, which is the gateway to the spiritual life, holds the first place among all the sacraments; through it, we are made members of Christ and of the body of the Church. And since death entered the universe through the first man, “unless we are reborn of water and the Spirit, we cannot” as the Truth says, “enter the kingdom of heaven” [John 3:5]. The matter of this sacrament is real and natural water; it makes no difference whether cold or warm.” (Denz. 696)
B. Council of Trent, Canons on Baptism (Canon 5):
”If anyone says that baptism is optional, that is, not necessary for salvation, let him be anathema.” (Denz. 861)
Also Trent: Canons on the Sacraments (Canon 4):
”If anyone says that the Sacraments of the New Law are not necessary for salvation, but that they are superfluous: let him be anathema.” (Denz. 847).
C. Benedict XIV (1740-58), Bull Nuper ad Nos (Solemn Profession of Faith Prescribed for Maronites; 1743):
“Likewise, I profess that Baptism is necessary for salvation.” (Denz. 1470)
D. Pope St. Zosimus, Apostolic Letter to the Oriental Churches (418):
”Not one of our children is held not guilty until he is freed through Baptism.” (Denz. 109a)
E. Council of Lyons E (1274) it was solemnly defined that:
”The souls of those who die in mortal sin or with original sin only, however, immediately descend to Hell, yet to be punished with different punishments.” (Denz. 464).
F. Council of Florence, Decree for the Greeks (1439):
”It is likewise defined that … the souls of those who depart in actual mortal sin or in original sin only, descend immediately into Hell but to undergo punishments of different kinds.” (Denz. 693)
Although not infallible, Vatican Council II said, “For there is one Mediator between God and men; Jesus Christ (1 Tim. 2:45). Neither is there salvation in any other” (Acts 4:12). Everyone, therefore must be converted to Christ, and everyone must become incorporated into Him by Baptism and into the Church which is His Body. In explicit terms Christ affirmed the necessity of faith and Baptism, and thereby affirms also the necessity of the Church; for through Baptism as though a door, men enter the Church.”
G. Council of Lateran IV, The Catholic Faith
“The sacrament of Baptism, which at the invocation of God and the undivided Trinity, namely, The Father Son and Holy Ghost, is solemnized in water …” (Denz. 430)
Here is your answer in a nutshell:
Infallible major premise: Baptism is necessary for salvation and is optional for no one. ( See infallible statements A, B and C above)
Infallible minor premise: True and natural water is necessary for salvation. (See infallible statements A and G above)
Infallible conclusion: Baptism in true and natural water is necessary for salvation and is optional for no one.
There are many more statements, made infallibly, on the necessity of Baptism. All of them address the ONE baptism of water. No dogmatic proclamations have been made on the so called “Baptism of Desire” nor on “Baptism of Blood.” As you know, infallible statements outweigh statements made by famous theologians, Saints and even Doctors of the Church.
