So, you’ve made your choice.
The second option is that Jesus established one, invisible, abstract, “spiritual” church made up of all true believers, regardless of which denomination they may attend on Sunday. In this view, the building where they gather and the gathering itself is not the church nor is the denomination to which they belong the church. The individual believer who has accepted Jesus Christ as his or her personal savior is considered to be a member of this “invisible” church, but the gathering of believers that come together for worship and fellowship is itself not the church. The church is bigger than the denomination, and this idea explains why it does not really matter why you can move from church to church each Sunday or change churches every few years when you don’t like the music ministry at the church you’re currently attending.
This is a very common view among non-Catholics, but is it true? Did Jesus establish a church that is only “spiritual” in nature, an abstract invisible church? The answer very plainly is, “No!”
"I do not pray for these only, but also for those who believe in me through their word, that they may all be one; even as thou, Father, art in me, and I in thee, that they also may be in us, so that the world may believe that thou hast sent me. The glory which thou hast given me I have given to them, that they may be one even as we are one, I in them and thou in me, that they may become perfectly one, so that the world may know that thou hast sent me and hast loved them even as thou hast loved me. (John 17:20-24)
Jesus prayed for unity – the unity that He shares with the Father and the Spirit – so that the world may know that the Father sent Jesus into the world. This must be a unity that the world can see. How could the world know with certainty that Jesus was sent, if they cannot see an “invisible” church? Can the world look at the state of Christianity today and see one, church? Do they say, “Yep, those Christians are certainly unified, that is plain to see. By looking at them, we can believe that Jesus was sent by God”? Not at all! The world cannot see any “invisible” unity because what it sees is 25,000+ denominations bickering and fighting. In order for the world to know the truth, it must be able to see a visible church.
Was Jesus just praying for unity among his Apostles? No, he prayed “also for those who believe in me through their word, that they may all be one” as we saw above. Jesus is saying the unity of a single, visible church is proof that He really was sent into the world by the Father. The unity of the church is supposed to be a witness to this fact. Is this the only place where the church is specified as “visible”? No!
“You are the light of the world. A city set on a mountain cannot be hidden.” (Matthew 5:14)
Jesus is not talking about an invisible, “spiritual” church; he says the church
cannot be hidden. He also says:
“If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother. But if he does not listen, take one or two others along with you, that every word may be confirmed by the evidence of two or three witnesses. If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.” (Matthew 18:15-17)
“Tell the church”? Which church? Where does one go to “tell it to the church” if it is merely a “spiritual” church? And how does one find it if it is invisible.
Further, what happens when there is a disagreement that requires a decision from the church as shown in the passage above. Let’s say that a wife becomes pregnant but does not want any more children; she wants to have an abortion. The husband goes to the Catholic Church which teaches that abortion is absolutely wrong. But the wife chooses a church that teaches that abortion is a matter of personal choice.
How can this matter be resolved since the “invisible” church – which is bigger than any one denomination – does not have doctrinal unity? How decided what is and is not true concerning the Christian faith? How decides what is and is not good doctrine? What is and is not moral? Who decides what is right and wrong? Who speaks for the church in these matters? Or what happens when everyone claims to speak for the church? This latter issue is actually what is occurring within Christianity today. Each pastor of every congregation is acting essentially as if he is the shepherd of his own flock. There are thousands upon thousands of pastors deciding upon the basis of their own individual understanding of scripture as to what is and is not good for their flocks.
