Heidelberg Q80

catechism heidelberg

What difference is there between the Lord's supper and the popish mass? The Lord's supper testifies to us, that we have a full pardon of all sin by the only sacrifice of Jesus Christ, which he himself has once accomplished on the cross; and, that we by the Holy Ghost are ingrafted into Christ. But the mass teaches, that the living and dead have not the pardon of sins through the sufferings of Christ, unless Christ is also daily offered for them by the priests. The mass at bottom is nothing else than a denial of the one sacrifice and sufferings of Jesus Christ, and an accursed idolatry.
