Catholicism was, and is, the only true, complete form of Christianity that ever existed.
Clearly opinions vary. ;-)
BTW, my take is that any group that teaches that about their group is, by definition, a cult.
Not if it was first and existed for 1,600 years before the wannabe's showed up....
your denomination is man made and has been around for a few hundred years....and you refer to Catholics as a cult???????
