The Roman ritual has a distinctive rite for adults. After investigation, every adult convert, invalidly or not baptized, receives Baptism unconditionally; if doubtfully baptized the conditional form, "If thou art not baptized, I baptize thee" etc., is employed. For valid reception, the adult should have at least the intention to receive the sacrament. For lawful and fruitful reception, he should know and believe the mysteries of the Catholic religion necessary for salvation, be instructed in Christian morality, and have supernatural sorrow for sin. Baptism given absolutely remits actual as well as original sin. In danger of death, when doubt arises concerning an adult's intention, Baptism is administered conditionally. See Baptism.
