The Church has two primary sacraments – baptism and Eucharist. The outward sign of baptism is water and the sign of the Cross made with chrism (blessed oil); the inner grace is new life in Christ. In Eucharist the outward sign is the bread and wine, and the inner grace is participation in God and being at one with fellow believers.
Five other sacramental rites are available in the Episcopal Church and are all vehicles of God’s grace, but are not rites that every Christian will necessarily be part of: Confirmation, Marriage, Reconciliation (private confession), Ordination, and Anointing at the Time of Death (“last rites”).
The word sacrament has to do with making something holy. The outward, tangible part of a sacrament reminds us that God uses the good creation he has made to be an avenue of divine grace and blessing for us.
