Q. 1. Does the Holy Bible provide any proof that Baptism is a Sacrament?
A. 1. Yes, it does. First of all, it must be made clear that the baptism of Saint John the Baptist was not a Sacrament. John's baptism was a symbol of repentance. The Christian Sacramental Baptism is one that confers grace to the individual. The baptism of repentance did not confer grace.
Beginning with the Acts of the Apostles in the New Testament. it is noted that the mentioned Christian Sacrament is one that confers grace. Through the Sacrament of Baptism, the believer receives the Holy Spirit. He is forgiven of his sins. And he becomes a member of the Body of Christ, the newly founded Catholic Church.
The Sacrament of Baptism is the doorway to the other Sacraments. Without it, you cannot receive the other Sacraments. It is also the doorway to the Kingdom of God. It transforms the individual from an outsider to an insider. Saint Philip believed that this was the only Sacrament necessary to administer on the Ethiopian Church.
