There exists a profound contrast between the teachings of Scripture and the teachings of Catholicism concerning the sacrifice of Jesus Christ. According to the Catechism of the Catholic Church, "the sacrifice of Jesus and the sacrifice of the Eucharist are one single sacrifice. The same Christ who offered Himself once in a bloody manner on the cross is contained and offered in an unbloody manner on church altars. It is truly propitiatory, which means it satisfies divine wrath. The Eucharist is thus a sacrifice because it re-presents (makes present) the sacrifice of the cross and is actually the body and blood, together with the soul and divinity of our Lord Jesus Christ (CCC, para.1366-67; 1374). Catholics express their faith in the real presence of Christ by worshipping and adoring the wafer as if it were the almighty and glorious God (para.1378). The Vatican teaches that every time the Mass is celebrated, the work of redemption is carried on (para.1405). The Catechism violates Scripture by teaching the Eucharist is offered repeatedly "in reparation for the sins of the living and the dead" (para.1414).

It is difficult to understand how Catholics can so easily reject the clear teaching of Scriptures which declare the perfect and finished work of Christ's redemption. "He, having offered one sacrifice for sins for all time, sat down at the right hand of God...by one sacrifice he has made perfect forever those who are being made holy...and where these [sins] have been forgiven, there is no longer any sacrifice for sin" (Hebrews 10:12,14,18). Christ did not enter a holy place made with hands, a mere copy of the true one, but into heaven itself, now to appear in the presence of God for us; nor was it that He should offer Himself often (Heb. 9:24-25).

We must tell Catholics that whenever the Eucharistic sacrifice for sin is offered, it as a blasphemous insult to the perfect and complete work of the Savior on Calvary's cross. Furthermore, we must warn Catholics they are committing the sin of idolatry when they worship the Eucharist as the Lord Jesus Christ. The sin is as grievous as when the Israelites worshipped the golden calf as the true God who delivered them out of Egypt (Exodus 32:4). Because of God's hatred of idolatry, that grievous sin brought death to 3000 Israelites. Catholics need to come out of their false religion and not participate in her sins any longer.
