Doctrine:Seven sacraments- baptism, confirmation, marriage, the last rites, ordination, the Eucharist (Mass or Holy Communion).The Mass is performed before the high altar by the priest. The Mass is a highly theatrical re-enactment of Christ's sacrifice.Transubstantiation- in the Eucharist the wine and bread are transformed into the body and blood of Christ. This miracle is worked by priests.Salvation is achieved through faith, good works, prayer and the cycle of confession- penance- absolution.
