Yes, and he also said ‘unless you eat the flesh of the Son of Man and drink His blood you do not have life within you’ in John 6. Are we to conclude from this that those who haven’t yet received First Communion are similarly unsaved and consigned to Limbo? Surely one who does not ‘have life within’ cannot enter heaven either?
If the two situations are not the same then why not? It is an equally strong statement as the one about baptism.
We must rely on the Church’s interpretation of Holy Scripture. The Church has always held as divinely revealed that no one can enter heaven without having been baptized, which Baptism can be by water, blood, or desire.
St. Thomas Aquinas, Summa, III, Q. 68, A. 1
“Consequently it is manifest that all are bound to be baptized: and that without Baptism there is no salvation for men.”
St. Thomas Aquinas, Summa, III, Q. 68, A. 2, Reply to Objection 3
“The sacrament of Baptism is said to be necessary for salvation in so far as man cannot be saved without, at least, Baptism of desire; ‘which, with God, counts for the deed.’ (Augustine, Enarr. in Ps. 57).”
St. Augustine, III de Anima
“If you wish to be a Catholic, do not believe, nor say, nor teach, that infants who die before Baptism can obtain the remission of original sin.”
Catechism of the Catholic Church, 1277
“Baptism is birth into the new life in Christ. In accordance with the Lord’s will, it is necessary for salvation, as is the Church herself, which we enter by Baptism.”
Baltimore Catechism, 154
“Q. Is Baptism necessary for salvation?
A. Baptism is necessary to salvation, because without it we cannot enter into the kingdom of heaven.”
Catechism of St. Pius X
“Q. Is Baptism necessary to salvation?
A. Baptism is absolutely necessary to salvation, for our Lord has expressly said: ‘Unless a man be born again of water and the Holy Ghost, he cannot enter into the Kingdom of God.’”
Or could it be just possibly
that an omnipotent God cannot be said to be restricted to operating within the form of the Catholic sacraments and them alone in this way?
He does operate outside the form of Catholic sacraments in regards to Baptism of Blood and Baptism of Desire. Both of these confer the sacramental effect, but they are not properly sacraments. See St. Thomas Aquinas’s
Summa Theologica, III, Q. 66, A. 11, Reply to Objection 2. And from the
Catechism of St. Pius X:
“Q. Can the absence of Baptism be supplied in any other way?
A. The absence of Baptism can be supplied by martyrdom, which is called Baptism of Blood, or by an act of perfect love of God, or of contrition, along with the desire, at least implicit, of Baptism, and this is called Baptism of Desire.”
