Yes, there is one Church, which consists of ALL those who’ve been adopted into the family of God.
You and I will never agree, it seems. It’s a paradigm thing. I consider the Church to consist of those whom the Lord has saved and adopted. You consider the Church to be the Roman Catholic institution.
Divisions are the work of men, not of God. This is something that we need to understand. Yes, everyone who believes in God will be saved, but that we are divided bodily betrays the truth of his Word.
I personally don’t think there is cause for such disagreement. I think all Christians should be Catholics if for nothing more then to preach the truth.
