Why is Jesus Christ the primordial sacrament?

Jesus is the Primordial Sacrament of the Father. By being the "Primordial Sacrament", Jesus Chriast is much more than simply the originator of the Sacraments. He is at once the SOURCE, the PRIMARY AGENT and the GOAL of all sacramental sctivity.
As SOURCE, Christ is the one in whom all the sacraments are rooted and from whom they derive their efficacy.
As PRIMARY AGENT, he is the one who, through the actions and words of the minister celebrating the various sacraments, baptizes, confirms, forgives, and reconciles, heals, offers himself in sacrifice, binds in faithful love and consecrates for service.
As Goal of all sacraments, Christ is the perfection toward which our life on earth tends.
