Then, please, become more proficient with clarity.
lol. A lot of us have found no amount of proficiency nor clarity can make up for a lack of eyes to see and ears to hear.
The word "catholic" means "universal," as in the universal Christian church referenced in the Nicene Creed.
Since the Roman Catholic church is not universal, the word means something different when prefaced by "Roman." It means allegiance to the papacy.
Clear enough? If not, you know what to pray for.
