Holy Baptism is appropriately administered within the Eucharist as the chief service on a Sunday or other feast.
Each candidate for Holy Baptism is to be sponsored by one or more baptized persons.
Sponsors of adults and older children present their candidates and thereby signify their endorsement of the candidates and their intention to support them by prayer and example in their Christian life. Sponsors of infants, commonly called godparents, present their candidates, make promises in their own names, and also take vows on behalf of their candidates.
Holy Baptism is especially appropriate at the Easter Vigil, on the Day of Pentecost, on All Saints' Day or the Sunday after All Saints’ Day, and on the Feast of the Baptism of our Lord (the First Sunday after the Epiphany). It is recommended that, as far as possible, Baptisms be reserved for these occasions or when a bishop is present.
