باتیستا (Baptism) is a Christian sacrament that symbolizes the purification and admission of a person into the Christian faith. It typically involves the use of water, which represents cleansing from sin. The act can be performed by sprinkling, pouring, or immersion, depending on the denomination's practices. In many Christian traditions, such as Catholicism and Protestantism, baptism is considered an important rite of passage. It is often performed on infants or new believers, signifying their commitment to follow Jesus Christ and their acceptance into the Christian community.
