Q. My Catholic colleague invited me to his wedding, where they celebrated mass as part of the ceremony. Is it alright to partake of their holy communion since they worship Jesus too?
A. My opinion is no, because Catholics attach a meaning to the Eucharist very different from Protestants. To Protestants, the bread and the wine represent the body and blood of Christ. The “is” in “this is my body” and “this cup is the new covenant” speaks of spiritual, not physical, reality. We partake of the Lord’s Supper in remembrance of Him.
• Lk 22:19-20 And he took bread, gave thanks and broke it, and gave it to them, saying, “This is my body given for you; do this in remembrance of me.” In the same way, after the supper he took the cup, saying, “This cup is the new covenant in my blood, which is poured out for you.
• 1 Co 11:24-25 and when he had given thanks, he broke it and said, “This is my body, which is for you; do this in remembrance of me.” In the same way, after supper he took the cup, saying, “This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me.”
The Catholic position is quite different. There are at least two issues. The first is transubstantiation, which is the changing of the substance of bread and wine, at the consecration in the Mass, into the substance of Jesus’ body and blood. The appearance of bread and wine remains, but Christ’s body and blood is really present.
Secondly, as a result of transubstantiation, “in the Mass, the same Christ who offered Himself once in a bloody manner on the altar of the cross, is present and offered in an unbloody manner. Consequently, the Mass is a truly propitiatory sacrifice …” (from Modern Catholic Dictionary by John A. Hardon). The Second Vatican Council claims that Christ instituted the Eucharistic Sacrifice “to perpetuate the sacrifice of His cross throughout the centuries until He should come again.”
This is contrary to Scripture, which nowhere teaches transubstantiation. Christ’s sacrifice was once for all, and never need to be repeated:
• Rom 6:10 The death he died, he died to sin once for all; but the life he lives, he lives to God.
• Heb 7:27 Unlike the other high priests, he does not need to offer sacrifices day after day, first for his own sins, and then for the sins of the people. He sacrificed for their sins once for all when he offered himself.
• Heb 9:12 He did not enter by means of the blood of goats and calves; but he entered the Most Holy Place once for all by his own blood, having obtained eternal redemption.
• Heb 9:26 Then Christ would have had to suffer many times since the creation of the world. But now he has appeared once for all at the end of the ages to do away with sin by the sacrifice of himself.
• Heb 10:10 And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all.
To Roman Catholics, Jesus’ sacrifice on the cross was not sufficient to obtain eternal redemption for all. He had to be sacrificed again and again in the Mass to propitiate God’s wrath, which blatantly contradicts God’s word. So, by partaking the Catholic Eucharist, the Christian by his action is concurring with this false doctrine, and crucifying the Son of God all over again and subjecting him to public disgrace (Heb 6:6).
Based on the above I would not partake of their Holy Communion. Actually, they may not permit non-Catholics to receive the bread, but that’s another story.
