The rite has its preponderant place in the liturgy of the Church. It belongs to the world of active mediations of religious attitude, ranging from the simplest gesture to the most elaborate celebration. Rites are therefore all actions oriented to religious expression, and in its genesis is the sacred, the divine, that which is pointed out as a mystery. The irruption of God in history through the incarnation and redemptive action of his Son, Jesus Christ, will enable the Christian liturgical rite to be a differentiating element of every other ritual form, that of always making reference to a full reality, that is in level of event which has already been effected, and he is aptly the image of that event, in the very likeness that binds it, brings the sign of the reality to which it refers. From the liturgical theology of the Constitution on the Sacred Liturgy Sacrosanctum Concilium, we try to understand how the liturgical rite, in its prime function of announcing and realizing, becomes the epiphany of the Paschal Mystery of Christ. In him, the mystery of Christ manifests itself in a clear and luminous way, giving the Church a profound experience.
