The Roman Catholic Church recognises seven sacraments. Most Christians agree that Baptism – the sacrament of initiation – and the Eucharist – the sacrament of unity – are foundational, and that the other sacraments, sacramentals, and rites flow from them. Every sacrament is an outward sign and a means of inward grace. In Baptism, water and oil form part of the celebration; in the Eucharist, bread and wine – which become the Body and Blood of Jesus Christ – are essential.
