Baptism is the sacrament that frees man from original sin and from personal guilt, that makes him a member of Christ and His Church. It is thus the door to a new and supernatural life.
Baptism is a true sacrament instituted by Christ. It is administered by washing with natural water and at the same time invoking the Most Holy Trinity. Since it confers grace by the signs’ being properly carried out, children can and should be baptized even while still infants. Baptism is necessary for salvation.
Baptism effects the remission of original sin and actual sins and of all punishment due to sin; it confers sanctifying grace, membership in Christ and in the Church and the obligation to obey the Church’s laws, and give an indelible character.
