The confession states that the Lord's Supper is not the actual sacrifice of Christ but rather a commemoration of Christ's one sacrifice for the remission of sins and an offering of praise to God. It explicitly condemns the Roman Catholic Church's teaching of "the popish sacrifice of the mass". It also rejects the Roman Catholic doctrine of transubstantiation, which states that after consecration by a priest the bread and wine miraculously become the body and blood of Christ. Rather, the confession teaches that communicants receive the body and blood of Christ and all the benefits of his death spiritually by faith, while the bread and wine remain physically unchanged. Ignorant, wicked and ungodly persons may eat the bread and wine, but they do not receive Christ. Instead, these unworthy persons are "guilty of the body and blood of the Lord" and commit great sin; for this reason, such persons should not be admitted to the sacrament.
