Sometimes I hear people complain that non-Catholic Christians are not allowed to take communion (the Eucharist) at Catholic Mass. After all, the word “catholic” means “universal,” and Catholicism considers all properly baptized people to be Christian. So, why exclude some Christians? Isn’t that kind of mean or uppity?

In Protestant circles, it is more common that Christians from other denominations are permitted to take communion “as long as they believe in Jesus.” So, what’s up with the Catholics? It doesn’t seem very welcoming, inclusive or universal.

The Church is indeed “universal.” The Church is for all peoples of all times in all places. However, “universal” does not apply to all principles and beliefs of all peoples. There are more things that unite Christians than divide us. Nevertheless, those things that divide us cannot be ignored. There is not perfect, universal unity in doctrine or practice. Jesus prayed that all of His followers would be one as He and the Father are one. The Church cannot accept every belief and doctrine in the name of inclusion. This is especially true where the Holy Eucharist is concerned.

With some exceptions, non-Catholic Christians generally believe that the communion service is a symbolic memorial intended to help us remember what Christ did for us. So, the bread and wine are about Christ. Catholics believe in transubstantiation. The bread and wine actually become Christ. The bread miraculously transforms into His literal flesh. The wine miraculously transforms into His literal blood (Jesus said, “He who eats my flesh and drinks my blood abides in me and I in him.” John Chapter six). The elements retain their outward appearance of bread and wine, but the substance has changed. This is an important distinction of beliefs that cannot be ignored. The Eucharist isn’t just about Christ, it is Christ. It’s not just a metaphor for Catholics.

“Communion” is an expression of unity among those who partake. Unless you believe that the bread and wine actually is Christ, it would be a false sign of unity for you to partake of the Eucharist. In other words, it would be a lie for both of us. One of us would be saying, “This is Jesus,” and the other would be saying, “This is not Jesus, it’s only about Jesus.” We would both be claiming a perfect unity that was not really genuine.

The other reason that non-Catholic Christians (or any non-Catholics) are typically not permitted to take communion is for your protection. In 1Corinthians chapter 11, The Apostle Paul warns against eating and drinking the Lord’s Supper without properly discerning it. Doing so can result in sickness, weakness or even damnation. Consequently, the Catholic Church doesn’t want you to take communion unless you properly understand and discern what you are doing. It’s for your own good for the Church to say, “Don’t take communion.”

It’s not about “exclusion” or “being mean” or “thinking we’re better Christians than you.” Anyone is welcome to come and participate in a Catholic Mass. Please, come join us. However, if you want to receive the Body and Blood of Christ, you must first enter into full unity with the Church. Otherwise, it becomes something less than an expression of genuine unity of faith (it’s not a real “communion”). It also places your soul in jeopardy. We don’t want that for you. We want only the best for you. We want you to have the fullness of the Universal Faith and the spiritual healing of the Eucharist, Jesus Himself.
