Why do you think scarlet and purple are Catholic colours?

Brother Johndc asked me this question. What makes me think the colors of the catholic church are purple and scarlet. He also stated that John the revelator couldnt have known about the catholic church. Let me find the the actual quote befor he erases it...."Dear Brother Bosco, do think about it. The Revelation of St. John the Divine was written before the end of the first century. How could its author have been referring to the Church in Rome at that time?"
Here we have the typical catholic who cant believe god knows the future. His god is a cement statue of a female, who can neither walk or talk. Now lets see...hhhhhmmmm, what makes me think that the dirty filthy murderous catholic cult dresses in purple and scarlet.
So he carried me away in the spirit into the wilderness: and I saw a woman sit upon a scarlet coloured beast, full of names of blasphemy, having seven heads and ten horns. And the woman was arrayed in purple and scarlet colour, and decked with gold and precious stones and pearls, having a golden cup in her hand full of abominations and filthiness of her fornication: And upon her forehead was a name written, MYSTERY, BABYLON THE GREAT, THE MOTHER OF HARLOTS AND ABOMINATIONS OF THE EARTH. And I saw the woman drunken with the blood of the saints, and with the blood of the martyrs of Jesus: and when I saw her, I wondered with great admiration. -Apocalypse (Revelation) 17:1-6
I guess if i were catholic id like all this to go away. But knowing me, i would believe scripture and get out of that false religion. God saw it and told it like it is. He nailed it and it is there for us to see now. Prophesy come to life. God is great. He tells the end from the beginning. The blind and confused catholic cant tolerate truth, thats why they have a catechism, cause the bible displays the filth that is in false religious systems, like the CC for example. The catholic cult plays the major roll in the tribulation, thats why its identified in the book of Rev. Does this answer your question brother John? Come on. Poke your head out from under that rock and say it aint so. You can do it. Show us what youre made of.
