<P> The Catholic Church sees the sacrament of confirmation as required to complete the grace given in baptism . When adults are baptised, confirmation is normally given immediately afterwards, a practice followed even with newly baptised infants in the Eastern Catholic Churches . In the West confirmation of children is delayed until they are old enough to understand or at the bishop's discretion . In Western Christianity, particularly Catholicism, the sacrament is called confirmation, because it confirms and strengthens the grace of baptism; in the Eastern Churches, it is called chrismation, because the essential rite is the anointing of the person with chrism, a mixture of olive oil and some perfumed substance, usually balsam, blessed by a bishop . Those who receive confirmation must be in a state of grace, which for those who have reached the age of reason means that they should first be cleansed spiritually by the sacrament of Penance; they should also have the intention of receiving the sacrament, and be prepared to show in their lives that they are Christians . </P> <P> For Catholics, the Eucharist is the sacrament which completes Christian initiation . It is described as "the source and summit of the Christian life". The ceremony in which a Catholic first receives the Eucharist is known as First Communion . </P> <P> The Eucharistic celebration, also called the Mass or Divine liturgy, includes prayers and scriptural readings, as well as an offering of bread and wine, which are brought to the altar and consecrated by the priest to become the body and the blood of Jesus Christ, a change called transubstantiation . The words of consecration reflect the words spoken by Jesus during the Last Supper, where Christ offered his body and blood to his Apostles the night before his crucifixion . The sacrament re-presents (makes present) the sacrifice of Jesus on the cross, and perpetuates it . Christ's death and resurrection gives grace through the sacrament that unites the faithful with Christ and one another, remits venial sin, and aids against committing moral sin (though mortal sin itself is forgiven through the sacrament of penance). </P> <P> The two sacraments of healing are the Sacrament of Penance and Anointing of the Sick . </P>
