Effects of Baptism:
All the effects of Baptism are supernatural as we should expect. These effects are mainly five and may be summarized in five words: sin, life, power, Church and character.
Removal of Guilt and Penalty for Sin:
The first and most practical effect of Baptism is to remove the guilt of original sin and restore the corresponding title to heavenly glory. What does this mean? It means that all the guilt of all the sin a person may have on his soul is taken away. A baptized child who has not reached the age of reason, if it dies, has an immediate title to the beatific vision. After the age of reason, a baptized person is freed not only from original sin but all the sins committed, and all the punishment due to even a lifetime of personal sins.
We should immediately add, however, that two penalties for original sin are not removed by Baptism. Our first parents lost for themselves and all their posterity the gift of bodily immortality and of freedom from irrational desires. Baptism does not restore either of these, what we call, preternatural gifts that we would have inherited had we not inherited a fallen human nature.
Supernatural Life:
By the sin of Adam, mankind lost its share in the divine life. By the death of Christ, the second Adam, this life can now be restored. Baptism restores what we call our supernatural life.
This is the new birth of which Christ spoke to Nicodemus, when He said that we must be born again of water and the Holy Spirit.
This is that life of which St. John writes in the opening chapter of his Gospel, when he says that we arechildren of God, who are begotten not by blood, nor by carnal desire nor by mans willing it, but by God (John 1:13). Because we have this life of God in our souls, we become heirs of heaven.
The only condition which God requires is that we remain spiritually alive when our bodies die. Provided we are in the grace of God when, as we say, we die, our souls will not only survive but will have a right to heavenly glory. In other words, this supernatural life received at Baptism is destined to continue, beyond our bodily death, into a heavenly eternity.
We have a name for the source of this supernatural life. We call it sanctifying grace. St. Augustine calls it the soul of the soul. What our soul is to our body, giving it natural life, sanctifying grace is to the soul, giving it supernatural life.
To be noted, however, is that sanctifying grace is already the created effect of the indwelling of the Holy Trinity. We may therefore say that the most important effect of the sacrament of Baptism is to have the Holy Trinity, Father, Son, and Holy Spirit, dwell in our souls. This indwelling is called the uncreated grace that we have received when we were baptized and are to retain when the Lord calls us to our everlasting destiny.
Virtues, Gifts and Fruits:
Baptism not only gives supernatural life to the soul, it also gives the soul supernatural powers, instincts and joys which we commonly identify as the virtues, gifts, and fruits of the Holy Spirit.
Another name for the virtues infused at Baptism is supernatural powers to do what is impossible to human nature alone. The three most important of these powers are the virtues of faith, hope and charity.
By faith we are empowered to believe everything which God has revealed: that God is the eternal Community of the Holy Trinity, Father, Son and Holy Spirit; that God became man in the person of Jesus Christ, the Son of Mary; that Jesus Christ, the Godman, suffered and died for our sins; that Jesus Christ is now present, really and truly, actually and bodily on earth in the Holy Eucharist; that the Church which Christ founded is our road to salvation, and that the visible head of this Church is the Bishop of Rome, successor of St. Peter, whom Christ made the rock, so that what the Pope teaches the universal Church, it is the teaching of Christ Himself.
By hope we are empowered to confidently trust that all the good things promised us by God we shall obtain; that we will never be without the light and strength we need to fulfill the will of God; that no trials that God sends us will be greater than, with His grace, we can bear; that provided we cooperate with Gods grace, heaven is ours. We are confident of His mercy, no matter how sinful our lives may have been. The only condition is that we repent, make a good Confession, and resolve to amend our lives.
By charity we are empowered to love God above all things; to love Him more than ourselves; to love Him even, or especially when He sends us sufferings and the cross; to love Him in all the circumstances of life, no matter how demanding His love may be.
By charity we are empowered to love others not only as much as we love ourselves. We are enabled to love others more than ourselves; to love others even as Christ has loved us, by suffering and dying on our cross out of love for others; to love others out of love for God constantly, patiently and generously beyond all human power and expectation.
Membership in the Church:
The Sacrament of Baptism incorporates a person into the Church founded by Christ. What does this mean? In the words of the Second Vatican Council, it means that All who have been justified by faith in Baptism are incorporated into Christ; they therefore have a right to be called Christians, and with good reason are accepted as brothers by the children of the Catholic Church.
Here we must distinguish. Every validly baptized person belongs to the Catholic Church no matter how unaware the person may be of belonging to the Mystical Body of Christ, which is the Church militant here on earth. However, we distinguish between belonging to the Church and being a member of the Church founded by Jesus Christ. To be an actual member of the Catholic Church, the baptized person must also be ready to profess what the Catholic Church teaches, and accept her laws and obligations with an open heart.
To belong to the Catholic Church further means that Baptism is the door to obtaining such graces as only baptized persons have a claim to. Certainly the Church is the universal sacrament of salvation and sanctification. All the graces that anyone receives from God are channeled through the Catholic Church. Those who are baptized have a special right to these graces to which no one else has a claim.
