The only reason someone would ask such a question is because they are uncertain of their own position on the subject. Is that what’s going on with you?
That is a non sequitur. I believe the Nicene Creed, which says: "We believe in one, holy, catholic, and apostolic Church".
But you seem not to believe that. You seem to believe that Christ has many brides. Am I misunderstanding you?
