In the context of the article, I will agree with you. The big "C" Catholic Church is Rome and while I believe that there is a remnant in that church, I too believe that it does NOT contain the whole body of believers.
However there is the small "c" catholic church which can be paraphrased as the "universal" church that does contain the whole of the body of Christ. Thus when we, as protestants, declare our faith using the Apostle's Creed, and we state that we "believe in the holy catholic church...". It does not mean that we are pledging allegiance to Rome, but rather acknowledging that we are members of a worldwide body and that we have communion with one another through Christ.
Amen. Selah!
We are the church as Christ lives IN each and every believer.
You don't *GO* to a church, you ARE the church.
1 Corinthians 3:16-17 Do you not know that you are God's temple and that God's Spirit dwells in you? If anyone destroys God's temple, God will destroy him. For God's temple is holy and you are that temple.
1 Corinthians 6:19-20 Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, for you were bought with a price. So glorify God in your body.
Matthew 18:20 For where two or three are gathered in my name, there am I among them.
Interestingly, the early church met in homes, not church buildings.

Romans 16:5 Greet also the church in their house. Greet my beloved Epaenetus, who was the first convert to Christ in Asia.
