What difference is there between the Lord's Supper and the papal Mass?

The Lord's Supper testifies to us that we have complete forgiveness of all our sins through the one sacrifice of Jesus Christ which he himself has accomplished on the cross once for all; (and that through the Holy Spirit we are incorporated into Christ, who is now in heaven with his true body at the right hand of the Father and is there to be worshiped.) But the Mass teaches that the living and the dead do not have forgiveness of sins through the sufferings of Christ unless Christ is again offered for them daily by the priest (and that Christ is bodily under the form of bread and wine and is therefore to be worshiped in them). Therefore the Mass is fundamentally a complete denial of the once for all sacrifice and passion of Jesus Christ ( and as such an idolatry to be condemned).
