Sorry but you can't get 'Catholic' out of that...It does not refer to 'all' churches...The 'all is in connection with Jedaea and Galilee...
And by looking at Revelation 1-3 we can see that the churches were not universal...So again, Catholic teaching right out the window...
Where else does your religious community believe there were churches at this time ?
