The Lord's supper testifies to us, first, that we have complete forgiveness of all our sins through the one sacrifice of Jesus Christ, which He Himself accomplished on the cross once for all;¹ and, second, that through the Holy Spirit we are grafted into Christ,² who with His true body is now in heaven at the right hand of the Father,³ and this is where He wants to be worshipped.⁴ But the mass teaches, first, that the living and the dead do not have forgiveness of sins through the suffering of Christ unless He is still offered for them daily by the priests; and, second, that Christ is bodily present in the form of bread and wine, and there is to be worshipped. Therefore the mass is basically nothing but a denial of the one sacrifice and suffering of Jesus Christ, and an accursed idolatry.
