1261 As regards children who have died without Baptism, the Church can only entrust them to the mercy of God, as she does in her funeral rites for them. Indeed, the great mercy of God who desires that all men should be saved, and Jesus' tenderness toward children which caused him to say: "Let the children come to me, do not hinder them,"[63] allow us to hope that there is a way of salvation for children who have died without Baptism. All the more urgent is the Church's call not to prevent little children coming to Christ through the gift of holy Baptism.
1283 With respect to children who have died without Baptism, the liturgy of the Church invites us to trust in God's mercy and to pray for their salvation.
[63] Mark 10:14 "Whom when Jesus saw, he was much displeased, and saith to them: Suffer the little children to come unto me, and forbid them not, for of such is the kingdom of God."
1 Timothy 2:4 "Who will have all men to be saved, and to come to the knowledge of the truth."
Additionally Luke 18:15-17 "And they brought unto him also infants, that he might touch them. Which when the disciples saw, they rebuked them. But Jesus, calling them together said: Suffer children to come to me, and forbid them not: for of such is the kingdom of God. Amen, I say to you: Whosoever shall not receive the kingdom of God as a child, shall not enter it."
Colossians 2:11-12 "In whom also you are circumcised with circumcision not made by hand, in despoiling of the body of the flesh, but in the circumcision of Christ: Buried with him in baptism, in whom also you are risen again by the faith of the operation of God, who hath raised him up from the dead."
SEVENTH SESSION, CANONS ON BAPTISM: "If anyone says that in the Roman Church, which is the mother and mistress of all churches, there is not the true doctrine concerning the sacrament of baptism, LET HIM BE ANATHEMA" (Canons on Baptism, Canon 3).
SEVENTH SESSION, CANONS ON BAPTISM: "If anyone says that baptism is optional, that is, not necessary for salvation, LET HIM BE ANATHEMA" (Canons on Baptism, Canon 5).
SEVENTH SESSION, CANONS ON BAPTISM: "If anyone says that children, because they have not the act of believing, are not after having received baptism to be numbered among the faithful, and that for this reason are to be rebaptized when they have reached the years of discretion; or that it is better that the baptism of such be omitted than that, while not believing by their own act, they should be baptized in the faith of the Church alone, LET HIM BE ANATHEMA" (Canons on Baptism, Canon 13).
On Being justified by FAITH OR WORKS:
SIXTH SESSION, CANONS CONCERNING JUSTIFICATION: "If anyone says that justifying faith is nothing else than confidence in divine mercy, which remits sins for Christ's sake, or that it is this confidence alone that justifies us, LET HIM BE ANATHEMA" (Canons Concerning Justification, Canon 12).
SIXTH SESSION, CANONS CONCERNING JUSTIFICATION: "If anyone says that the justice received is not preserved and also not increased before God through good works, but that those works are merely the fruits and signs of justification obtained, but not the cause of its increase, LET HIM BE ANATHEMA" (Canons Concerning Justification, Canon 24).
SIXTH SESSION, CANONS CONCERNING JUSTIFICATION: "If anyone says that the Catholic doctrine of justification as set forth by the holy council in the present decree, derogates in some respect from the glory of God or the merits of our Lord Jesus Christ, and does not rather illustrate the truth of our faith and no less the glory of God and of Christ Jesus, LET HIM BE ANATHEMA" (Canons Concerning Justification, Canon 33).
FOURTEENTH SESSION, CANONS CONCERNING THE MOST HOLY SACRAMENT OF PENANCE: "If anyone says that in the Catholic Church penance is not truly and properly a sacrament instituted by Christ the Lord for reconciling the faithful of God as often as they fall into sin after baptism, LET HIM BE ANATHEMA" (Canons Concerning the Most Holy Sacrament of Penance, Canon 1).
FOURTEENTH SESSION, CANONS CONCERNING THE MOST HOLY SACRAMENT OF PENANCE: "If anyone denies that sacramental confession was instituted by divine law or is necessary to salvation; or says that the manner of confessing secretly to a priest alone, which the Catholic Church has always observed from the beginning and still observes, is at variance with the institution and command of Christ and is a human contrivance, LET HIM BE ANATHEMA" (Canons Concerning the Most Holy Sacrament of Penance, Canon 7).
FOURTEENTH SESSION, CANONS CONCERNING THE MOST HOLY SACRAMENT OF PENANCE: "If anyone says that the confession of all sins as it is observed in the Church is impossible and is a human tradition to be abolished by pious people; or that each and all of the faithful of Christ or either sex are not bound thereto once a year in accordance with the constitution of the great Lateran Council, and that for this reason the faithful of Christ are to be persuaded not to confess during Lent, LET HIM BE ANATHEMA" (Canons Concerning the Most Holy Sacrament of Penance, Canon 8).
FOURTEENTH SESSION, CANONS CONCERNING THE MOST HOLY SACRAMENT OF PENANCE: "If anyone says that God always pardons the whole penalty together with the guilt and that the satisfaction of penitents is nothing else than the faith by which they perceive that Christ has satisfied for them, LET HIM BE ANATHEMA" (Canons Concerning the Most Holy Sacrament of Penance, Canon 8).
All these articles from TRENT were considered the complete spelling out of certain doctrines. It is clear from the Doctrine on Baptism, that BAPTISM numbers a child among the faihful. That means that BAPTISM is necessary for SALVATION according to the Catholic Church, even though the child has no means to believe or understand what is going on, therefore no FAITH in what is happening, and that is against Scripture.
The Bible teaches otherwise.
