For me lower case simply means I give less significane to the church, as catholics represent themselves as the one and only true church...which we know isn’t true.
I do not believe catholic means universal as catholics do, and for that matter what others might believe or want it to mean ‘with regards to church’....rather it’s prefered today that the “Body of Christ” be used, as it’s written, which includes ALL believers who are in Christ.
Additionally....If one adheres to the “Universal Church” language then that does lend one to flow along with the ‘One World Church’ we are warned about...which today often signifies itself as the “Universal Church”.
Personally I have no problem with saying “Roman Catholic” (with the Roman included) any more than saying “Presbyterian” or “Methodist.” I might even say “Catholic” for short.
That is the standard way to express the name of a denomination.
If I really DO mean the universal church of all believers, then I might say lower-case “catholic.” This is found through most denominations.
I find that hate-based typography is not gainful. It creates an extra layer of stuff to hack through in discussions.
Sadly, but not surprisingly the thread has morphed into the same old same old. And, we cannot seem to get any discussion on the points raised in the OP.
Wonder why that is.
Which we only need watch the current efforts to bring all religions together lead by the pope to understand is already happening.
