The saving words and actions of Jesus Christ are the foundation of what God communicates to us in the Sacraments of the Church. Guided by the Holy Spirit, the Church recognizes the existence of Seven Sacraments instituted by the Lord. They are the Sacraments of Initiation (Baptism, Confirmation, the Eucharist), the Sacraments of Healing and Reconciliation (Penance and the Anointing of the Sick), and the Sacraments at the Service of Communion (Marriage and Holy Orders). Through the Sacraments, God shares his holiness with us so that we, in turn, can make the world holier.
The visible reality we see in the Sacraments is their outward expression, the form they take, and the way in which they are administered and received. The invisible reality we cannot "see" is God's grace, his gracious initiative in redeeming us through the death and Resurrection of his Son. His initiative is called grace because it is the free and loving gift by which he offers people a share in his life, and shows us his favor and will for our salvation. Our response to the grace of God's initiative is itself a grace or gift from God by which we can imitate Christ in our daily lives.
