"Holy Baptism is the basis of the whole Christian life, the gateway to life in the Spirit and the door which gives access to the other sacraments. Through Baptism we are freed from sin and reborn as sons of God; we become members of Christ, are incorporated into the Church and made sharers in her mission: "Baptism is the sacrament of regeneration through water in the word." -CCC 1213
"Those who approach the sacrament of Penance obtain pardon from God's mercy for the offense committed against Him, and are, at the same time, reconciled with the Church which they have wounded by their sins and which by charity, by example, and by prayer labors for their conversion." -CCC 1422
"At the Last Supper, on the night He was betrayed, our Savior instituted the Eucharistic sacrifice of His Body and Blood. This He did in order to perpetuate the sacrifice of the cross throughout the ages until He should come again, and so to entrust to His beloved Spouse, the Church, a memorial of His death and resurrection: a sacrament of love, a sign of unity, a bond of charity, a Paschal banquet 'in which Christ is consumed, the mind is filled with grace, and a pledge of future glory is given to us... The Eucharist is the source and summit of Christian life." -CCC 1323-1324
"Baptism, the Eucharist, and the sacrament of Confirmation together constitute the "sacraments of Christian initiation," whose unity must be safeguarded. It must be explained to the faithful that the reception of the sacrament of Confirmation is necessary for the completion of baptismal grace. For "by the sacrament of Confirmation, [the baptized] are more perfectly bound to the Church and are enriched with a special strength of the Holy Spirit. Hence they are, as true witnesses of Christ, more strictly obliged to spread and defend the faith by word and deed."- CCC 1285
"The matrimonial covenant, by which a man and a woman establish between themselves a partnership of the whole of life, is by its nature ordered toward the good of the spouses and the procreation and education of offspring; this covenant between baptized persons has been raised by Christ the Lord to the dignity of a sacrament." - CCC 1601
"By the sacred anointing of the sick and the prayer of the priest the whole Church commends those who are ill to the suffering and glorified Lord, that He may raise them up and save them. And indeed she exhorts them to contribute to the good of the People of God by freely uniting themselves to the passion and death of Christ."- CCC 1499
"Holy Orders is the sacrament through which the mission entrusted by Christ to His apostles continues to be exercised in the Church until the end of time: thus it is the sacrament of apostolic ministry. It includes three degrees: episcopate, presbyterate, and diaconate." -CCC 153
