Heidelberg Catechism - Question 78
Q
78
Are then the bread and wine changed into the real body and blood of Christ?
A
No. Just as the water of baptism is not changed into the blood of Christ and is not the washing away of sins itself but is simply God's sign and pledge, so also the bread in the Lord's supper does not become the body of Christ itself, although it is called Christ's body in keeping with the nature and usage of sacraments.
