Sacraments for Salvation
Below are quotes taken from the Catechism of the Roman Catholic Church. The numbers indicate the section where these quotes can be found in the Catechism. It contains official doctrines of the Roman Catholic Church.
#1129 The Church affirms that for believers the sacraments of the New Covenant are necessary for salvation…. The fruit of the sacramental life is that the Spirit of adoption makes the faithful partakers in the divine nature by uniting them in a living union with the only Son, the Saviour.
#980 It is through the sacrament of Penance that the baptized can be reconciled with God and with the Church: “Penance has rightly been called by the holy Fathers `a laborious kind of baptism.’ This sacrament of Penance is necessary for salvation for those who have fallen after Baptism, just as Baptism is necessary for salvation for those who have not yet been reborn” (Council of Trent (1551): DS 1672; cf. St. Gregory of Nazianzus, Oratio 39, 17: PG 36,356).
#1446 Christ instituted the sacrament of Penance for all sinful members of his Church: above all for those who, since Baptism, have fallen into grave sin…It is to them that the sacrament of Penance offers a new possibility to convert and to recover the grace of justification…The Fathers of the Church present this sacrament as “the second plank [of salvation] after the shipwreck which is the loss of grace.
#1493 One who desires to obtain reconciliation with God and with the Church, must confess to a priest all the unconfessed grave sins he remembers after having carefully examined his conscience. The confession of venial faults, without being necessary in itself, is nevertheless strongly recommended by the Church.
#1456 All mortal sins of which penitents after a diligent self-examination are conscious must be recounted by them in confession, even if they are most secret and have been committed against the last two precepts of the Decalogue. … those who fail to do so and knowingly withhold some, place nothing before the divine goodness for remission through the mediation of the priest, `for if the sick person is too ashamed to show his wound to the doctor, the medicine cannot heal what it does not know.’
#1257 The Lord himself affirms that Baptism is necessary for salvation. He also commands his disciples to proclaim the Gospel to all nations and to baptize them. Baptism is necessary for salvation for those to whom the Gospel has been proclaimed and who have had the possibility of asking for this sacrament. The Church does not know of any means other than Baptism that assures entry into eternal beatitude.
#1304 Like Baptism which it completes, Confirmation is given only once, for it too imprints on the soul an indelible spiritual mark, the “character,” which is the sign that Jesus Christ has marked a Christian with the seal of his Spirit by clothing him with power from on high so that he may be his witness.
#1310 To receive Confirmation one must be in a state of grace. One should receive the sacrament of Penance in order to be cleansed for the gift of the Holy Spirit. More intense prayer should prepare one to receive the strength and graces of the Holy Spirit with docility and readiness to act.
