The capital C came to distinguish the Church from those folks that walked away....like capitalizing some young person’s pronoun. ...catholics accepted that and the walk aways accepted it and took new names...and became uncomfortable about using the c word altogether.
Kind of like Catholics not using Christian so much to avoid confusing fellow catholics with protestants and orthodox in discussion....like using plural pronouns and verbs referring to a singular freak these days....confusing as all get out!
C....became C...to reveal the universality, original, true, versus the offshoots.
Not saying the human Church wasn’t corrupted and in need of reform...its men...just never its teaching. That remained and always will, despite failing men like McCarrick and Francis and me.
The Roman Catholic Church has never been the holy catholic Church and never will be. The Roman denomination has been corrupt from the beginning and is now frankly apostate. The catholic Church is made up of all believers who have washed their robes in the Blood of Christ and have found salvation in Him and His finished work on the cross alone. They can be found in many earthly denominations.
