Final answer:
Baptism is considered a sacrament of faith in the case of infants as it cleanses them from original sin and initiates them into the Christian faith.
Step-by-step explanation:
Baptism is still considered a sacrament of faith in the case of infants because it is believed to cleanse them from original sin and initiate them into the Christian faith. Although infants cannot make a conscious decision to follow Christ, their parents and godparents make a declaration of faith on their behalf during the baptismal ceremony. This act of faith is seen as an act of trust in God's grace and a commitment to raise the child in the Christian faith.
