The difference between Christianity and Catholicism

[Creaky]

The Protestant churches might like to claim more authenticity, but the original church (which didn't change much because it was so rigid) is the Catholic church.  While the early Church fathers might recognize a lot of what's in the Catholic church as being of their faith, they'd be puzzled (or horrified by) by sects such as the Pentecostals.

So, there was no church before Constantine, before Rome took it over, Christianity didn’t exist, really? 
is that what you are implying? 

I am Not a Pentecostal or charismatic so not my job to defend them but there are charismatic Roman Catholics

And they follow the Nicene creed, meaning they would be accepted
