Actually The Catholic Church beleives in an invisible church.
Hence statments of seperated brethren, Jews, and Muslims share in the plan of salvation. Some are catholic they just don’t know it yet.
The big difference is that the church also beleives in a visible chuch on earth. The invisible part gets worked out whereby those physically sepearted from the church reunites with the other part of the Catholic Church in heaven. Known as the church triumphant. THe Catholic Church that is visible on earth is the church militant.
The church in the bible is clearly one visible church that declared unfied dcontrine had unified church councils and so forth.
Not the chaos we see in protestantism. The church in the Bible sopke for Christ and declared doctrine for not only its members but to the angels in heave. Now thats the power to bind and loose.
Ephesians 3
8 To me, who am less than the least of all the saints, this grace was given, that I should preach among the Gentiles the unsearchable riches of Christ, 9and to make all see what is the fellowship
1] of the mystery, which from the beginning of the ages has been hidden in God who created all things through Jesus Christ;
2] 10to the intent that now the manifold wisdom of God might be made known by the church to the principalities and powers in the heavenly places,
No protestant church can claim this divine authority to teach not do they even dare attempt so. The mere fact there are thousands of competing churches using the authority of the Bible alone would make theat postion laughable. What you hear is that we aagree on the essentials and disagree on the unessentials. Sorry Jesus told the aposltes to go into the world and preach and teach them all things not some essential things and let them disagree on some things just give them the Bible and let them figure it out.
