Seriously Jvette you need to realize that the beliefs that Catholics and Protestants share existed long before the RCC was ever formed. You keep trying to convince us that the RCC was Jesus. It is not. The beliefs that are common to both come from Jesus. Not the RCC.
The beliefs were those of Christians as they still are today.
There is no Roman Catholic Church, it is the universal church in Rome.
The distinction of Catholic and protestant is a man made one, but alas, one that serves a purpose.
