People still don't seem to get it.
The use of "Roman Catholic" was British imposed, as they were of the view that the CofE was "Catholic", and hence was a "Catholic Church".
Internally, the Catholic Church is simply the Catholic Church, and many clergy resented the English imposition of "Roman Catholic".
Not entirely. Not really about the 'hated English' per se. Perhaps about any protestant religion
The Anglican church also talks of the 'catholic church' in the Nicene creed.
We say
"We believe in one holy catholic and apostolic Church. We acknowledge one baptism for the forgiveness of sins. We look for the resurrection of the dead, and the life of the world to come.'
Catholic has a dictionary meaning of 'all embracing'.
The idea that I have is that catholic mean all embracing and having been baptised once in any church you don't need to be rebaptised to join any other church. My grandfather who trained as a Catholic priest, then left and later married my grandmotherr was very clear on this.
His oldest two children were baptised by a travelling Anglican priest here in NZ were taken from his home when he was away, under protest by my grandmother who had just recently given birth by parishioners of the local RC church and ostensibly baptised again. He apparently was apoplectic about this.
https://en.wikipedia.org/wiki/Nicene_Creed#:~:text=The%20Nicene%20Creed%20of%20325,very%20God%20of%20very%20God.%22I have the feeling that scholars like my grandfather (died 1940) was did not tend to go much on trying to make differences out of Catholic/Roman Catholic. I know though that some did and that is fine too.
But I know it did happen.
