Βάπτισμα (Baptism) is a Christian sacrament that symbolizes the initiation of a believer into the faith. It typically involves the use of water, which represents purification and the washing away of sins. The act can be performed by immersion, pouring, or sprinkling, depending on the tradition of the church. In many Christian denominations, such as Roman Catholicism, Orthodox Christianity, and Protestantism, baptism is considered an essential rite. It is often performed on infants or new believers and is seen as a public declaration of faith in Jesus Christ. The ceremony may also include prayers and blessings from a clergy member.
