Except that "the Church" is NOT wholly the Roman Catholic church.. for the Roman Catholic Church is merely "A church".. a denomination of the church.. a club.. a mere view of the revelation.. As the book of revelation indicates.. Which is the Revelation of Jesus Christ NOT the revelation of John..
Christ said “I shall build my Church”, singular. St. Paul asked, rhetorically, “Is Christ divided?”. There is one Holy Catholic and Apostolic Church as defined by the baptism and the Creed. Christ revealed nothing to the “denominations”.
