Q. Since, then, faith alone makes us share in Christ and all his benefits, where does such faith originate?
A. The Holy Spirit creates it in our hearts by the preaching of the holy gospel, and confirms it by the use of the holy Sacraments.
Q. What are the Sacraments?
A. They are visible, holy signs and seals instituted by God in order that by their use he may the more fully disclose and seal to us the promise of the gospel, namely, that because of the one sacrifice of Christ accomplished on the cross he graciously grants us the forgiveness of sins and eternal life.
Q. Are both the Word and the Sacraments designed to direct our faith to the one sacrifice of Jesus Christ on the cross as the only ground of our salvation?
A. Yes, indeed, for the Holy Spirit teaches in the gospel and confirms by the holy Sacraments that our whole salvation is rooted in the one sacrifice of Christ offered for us on the cross.
Q. How many Sacrament has Christ instituted in the New Testament?
A. Two, holy baptism and the holy Supper.
