Hi I am currently in a dialouge with a good friend who is Baptist. What is a good way to explain that the Catholic Church is the fullness of the faith? Should I start with Authority? Scripture? what?
Is this also a logical arguement:
If Christ founded Church X and that Church believes and teaches A-F.
And Church Z came out of Church X but only believes in G and H. Then Church X contains the beliefs of Z AND X?
