mommamia… sorry for calling you a sir

i just thought the mommamia was used as an expression sorry…
But here i quote this part because you stated above that an already broken institution continues to break.
Well, let’s look at this…
There are six Orthodox churches that are not in communion with the autocephalous churches.
