re: Cornelius - He was baptised. Why is the Sacrament of Baptism necessary for those who have supposedly had their sins remitted?
St. Thomas says it is necessary both for the complete abolition of all temporal punishment, and St. Robert for full incorporation into the Body of the Church. Both St. Thomas and St. Robert say Cornelius was within the Church, and would have been saved if he had died. But the obligation to receive the Sacrament of Baptism remains, and BOD does not confer the Sacramental Character, otherwise Baptism would not have been conferred on Cornelius, since the character cannot be impressed twice. Cornelius is a post-Resurrection example of justification by BOD. It shows the Church's teaching on BOD is accurate and is found in Scripture itself.
Because BOD by definition does not remit temporal punishment, does not confer the sacramental character, does not incorporate one into the Mystical Body of Christ, the Church. But we know also from the teaching of the popes that justification, since the promulgation of the Gospel (the founding of the Church) cannot be had without the Sacrament of Baptism.
Justification cannot be had, since the promulgation of the Gospel, "without the laver of regeneration, or without the desire thereof".
re: St Mary Magdalene, the Good Thief, the Holy Innocents - all prior to the promulgation of the Gospel. Not relevant.
Why not? Where is the positive proof that BOD, if it justified prior to the promulgation of the Gospel, as you admit, ceased to justify after that? Even John 3 was prior to the promulgation of the Gospel, yet those who deny BOD claim it supports their view. John 14 was years after John 3, yet Our Lord there taught that those who love Him truly will receive the remission of our sins. There is no Scriptural basis for thinking that Love of God and Perfect Contrition ceased to justify after Christ's Resurrection.
Burden of proof is on those who claim BOD ceased to apply after the Resurrection to show it. And I gave one post-Resurrection example.
There is a tradition of the Church that even Our Lady was baptised. But certainly St Mary Magdalene was baptised as were all the Apostles and disciples who lived before the founding of the Church and continued to live after the founding.
I agree Our Lady was baptized, though obviously She was sanctified right from Her Immaculate Conception. Ven. Mary of Agreda speaks of the great devotion with which She used to receive the Holy Eucharist, which She received after being baptized.
The issue is not that St. Mary Magdalene was not baptized. The issue is that she received the remission of sins immediately as a reward for her perfect love of God and contrition, as Christ said. Fr. Haydock and all the Catholic Commentaries teach this.
But if it is possible to be saved by BOD, wouldn't that extend to all Protestants, schismatics, and traditionalist "heretics"
Protestants are already Baptized, so BOD would not apply to them. It is possible to belong to the Soul of the Church if, for e.g. one is unjustly excommunicated. St. Robert says this, and says such a person belongs to the Soul of the Church inwardly, but not the Body.
who disagree with your interpretation of dogmas which, by the way, no one is permitted to interpret? I assent to the literal meaning of all the dogmas of the Church. Can you say the same?
If Trent had meant to say "Unlike Confession and the Eucharist, there is no voto for Baptism", it could have easily done so, and I would assent to it. What Trent did say is that we cannot be saved without Baptism or its desire. I assent to what Trent literally taught.
As I mentioned, Pope Bl. Pius IX told us we are bound to what Catholic Theologians hold to belong to the Faith. I do not believe there is a contradiction between what Trent taught and what the Doctors and Theologians teach. Baptism is necessary in re or in voto.
That is the Tridentine dogma, repeated in Canon Law, all Catechisms, all the Doctors and Saints post-Trent, all the Theology Manuals etc.
God Bless.
