Of course. Some are a direct revelation. Most, record historical fact prior known as tradition:
[1] Forasmuch as many have taken in hand to set forth in order a narration of the things that have been accomplished among us; [2] According as they have delivered them unto us, who from the beginning were eyewitnesses and ministers of the word: [3] It seemed good to me also, having diligently attained to all things from the beginning, to write to thee in order, most excellent Theophilus, [4] That thou mayest know the verity of those words in which thou hast been instructed. (Luke 1)
St. John , the author of the Revelation that you cite, also indicates that he knows more that he is telling in the scripture:
there are also many other things which Jesus did; which, if they were written every one, the world itself, I think, would not be able to contain the books that should be written. (John 21)It is rare exception that a direct revelation is written, like the Revelation of St. John or the Ten Commandments. Normally, the Evanglelists recorded what had been a tradition for a while.
It has been said....”you don’t listen and respond to what’s said in a way that indicates you actually understand the point at issue..... Instead you hear something, categorize it according to the template you have before you, and choose whichever talking point most closely approximates an item on the menu of your template. It is like talking not to a man but to a machine.
Now instead of simply a comment you are using this as a means of doing just that...yet again.
