What is definition christening?

Christening is a religious ceremony in which a child is baptized and given a Christian name by a member of the clergy. It is also known as baptism or infant baptism and is most commonly practiced within the Roman Catholic, Anglican, and Orthodox churches. The ceremony involves the application of water onto the forehead of the child while a minister recites a prayer and makes the sign of the cross. In some traditions, the child is also anointed with oil. The purpose of christening is to welcome the child into the faith and to cleanse them of original sin, according to Christian doctrine. It is considered an important milestone for a child, and family and friends often gather to celebrate the occasion with gifts, food, and drinks.
