When things were normal in the Catholic world, ie Catholics had the Vatican,
obviously, there were more Churches in the world than just the ones @ the Vatican.
And all Catholic churches are different insome way or another. But they all USED to (until 1958) teach thesame things:
you have to be baptized
infants are also
7 Sacraments
must die in state of grace, no unrepented of mortal sins or you end up in Hell
etc... etc..
Today, who knows what you get w/ any given Catholic Church, unless you attend Mass at a Sedevacantist Church. Then you get the real deal.
