Why is Baptism important? What change does it make in me?

The Lord himself affirms that Baptism is necessary for salvation. “No one can enter the Kingdom of God without being born of water and the Spirit” (Jn 3:5). Christ commanded his disciples to preach the Gospel, draw people to faith in him, and baptize those who come to conversion. The Church does not neglect the mission she has received from Christ to ensure that all be baptized and reborn of water and the Spirit.


By Baptism all sins are forgiven, Original Sin and all personal sins, and temporal punishment due to sin is removed. After one has been reborn in Christ, there is nothing to prevent one’s entry into God’s Kingdom.

However, though all sins are removed, there remains, as an effect of Original Sin, the inclination to sin that is called concupiscence. This inclination to sin shows itself in what is sometimes referred to as a darkening of the mind and a weakening of the will, that is, the inability to know clearly the right or wrong of an action and/or the lack of strength to resist temptation and always to do the right thing no matter how hard this is. The effects of Original Sin need not harm us so long as we seek strength to resist them through the Sacrament of Penance, the Sacrament of the Eucharist, prayer, a deepening spirituality, growth in virtue, and a wholehearted dependence on God.

Baptism also gives us new life as adopted children of God. We become sharers of divine life and temples of the Holy Spirit. We are now made righteous by God and live in a state of grace, that is, we live in union with God because of his gracious and loving initiative. Our permanence in the state of grace is called sanctifying grace because God “sanctifies” us, that is, makes us his holy people by giving us his life. God continues to assist us by many helps that are called actual graces. Thus, we have the ability to live and act under the guidance and light of the gifts of the Holy Spirit. This helps us mature in goodness through the practice of virtues, such as the Cardinal Virtues: prudence, justice, temperance, and fortitude.

By Baptism we become members of the Church, the Body of Christ. We share in the priesthood of Christ as well as his prophetic and royal mission. “You are ‘a chosen race, a royal priesthood, a holy nation, a people of his own, so that you may announce the praises’ of him who called you out of darkness into his marvelous light” (1 Pt 2:9). We enjoy the community we find in the Church, share our talents and gifts with its members, respond willingly to its teachings and requirements, and assume the responsibilities that our membership implies.

Baptism provides a common foundation among all Christians, including those not yet in full communion with the Catholic Church. The Church recognizes the validity of Baptism in other Christian Churches as long as the rite involved the pouring of or immersion in water, a Trinitarian formula, and the intention to baptize. Those who have been baptized have been saved by their faith in Christ and the grace of Baptism. “They therefore have a right to be called Christians and with good reason are accepted as brothers [and sisters] by the children of the Catholic Church” (CCC, no. 1271, citing UR, no. 3).

“Incorporated into Christ by Baptism, the person baptized is configured to Christ. Baptism seals the Christian with the indelible spiritual mark (character) of his belonging to Christ. No sin can erase this mark, even if sin prevents Baptism from bearing the fruits of salvation. Given once for all Baptism cannot be repeated” (CCC, no. 1272). This spiritual mark is also called a character, which St. Augustine likened to distinctive brandings impressed upon soldiers and slaves during Roman times to signify the commander or owner to whom they belonged. Baptism marks us permanently as belonging to Christ, whose image we bear.
