What is so very interesting about this thread is that it uncovers one of the absolutely fundamental differences between the Catholic and Orthodox Churches, and Protestant denominations. Protestants largely believe that going to church is primarily about hearing a sermon and being instructed in the faith, as well as bringing the community of Christ together. It is about praising God, but not precisely the physical
worship of God. The Catholic Church believes that the point of going to church is the actual
worship of God. Since we believe in Transubstantiation, we believe that Jesus is physically present in the room with us. We are literally bowing down before our Savior physically present and praising him. We are outside of time, watching the re-presentation of the Sacrifice of Christ on Calvary itself. As such, it also serves as a sacrament of initiation, along with baptism and confirmation. It is called communion because we are demonstrating that we are acting in communion with one another and believe all that the Catholic Church teaches. Likewise, at the Last Supper, the Apostles were signing onto their mission to follow Jesus precisely as he instructed them. Even then, one Apostle, Judas, received unworthily and went on to betray Christ. Of course, he eventually suffered the consequences. It is important to note that the Eastern Orthodox, Oriental Orthodox, and other churches, such as the Assyrian Church of the East, also practice closed Communion and believe in Transubstantiation in the same way that Catholics do. As such, the VAST majority of Christians worldwide actually do NOT believe in open communion (about 77% of all Christians). If you do
not believe in Transubstantiation and receive communion, for Catholics, this would be a form of blasphemy and heresy, as you are receiving something that you don’t even believe in. There are MANY other forms of ecumenism that are possible besides the sharing of communion.
To me, it is a great sign of ecuminism and unity in the body. I have a hard time when anyone from any denomination assumes that they have it completely right; when they state that others cannot partake because they assume they are not a part of the Church.
Interestingly, I’ve always been just as troubled about open communion as many Protestants are about closed communion. It would never have even entered my head, even if my church allowed it, to receive communion in another denomination if they did not share the belief in the Real Presence. (Communion between Orthodox and Catholics is possible in very rare circumstances, because they share the core belief in Transubstantiation). There’s another issue that’s not being addressed here, and that is the belief in absolutism vs. relativism. Protestants tend to believe in relativism as so far as personal interpretation of the Bible is allowed. As long as it doesn’t affect salvation, a wide range of belief is tolerated. Catholics and Orthodox believe that the Church speaks for Christ, and that there
must be a basic consensus. Both points of view
cannot be correct, and that’s the problem. For Catholics (and Orthodox), either their religion is wholly correct, or it is not. I wouldn’t be Catholic if I believed it to be only
partially correct. To me, the whole point of following a denomination is that you think they have their beliefs totally right. If you don’t, why on earth are you following them?!
