In explaining the sacramental system of the church or the sacramental economy, the Catechism dedicates one chapter on the Paschal Mystery in the Age of the Church. It teaches that "In the liturgy of the Church, it is principally his own Paschal mystery that Christ signifies and makes present. During his earthly life Jesus announced his Paschal mystery by his teaching and anticipated it by his actions. When his Hour comes, he lives out the unique event of history which does not pass away: Jesus dies, is buried, rises from the dead, and is seated at the right hand of the Father 'once for all.'
