so you are advocating a Quaternity nature of God. We'll see how that flies.In the present tense, referring to the "that which" was from the beginning, they could see, hear, and touch it. That implies that what John is referring to is touchable in the beginning just as it was in John's present. So it didn't change and is still tangible now and has always been tangible. John is referring to the Word of Life in this entire context. He isn't describing an incarnating, but rather something that was revealed by Jesus. The entire narrative about John 1's Word should incorporate what John also wrote in 1 John 1. I believe this only clarifies what he meant. He also calls the Word of Life an it in this passage. Most translators I have seen say this.
Actually what you should be advocating then is that the twelve apostles and other disciples existed eternally.
Either way, you are presenting new concepts of reality that seem to diverge from the rest of scripture.
But in reality Christ's eternal existence is not a problem. The apostles saw the Word (who has existed eternally) incarnate. That does not contradict what we see throughout scripture. There is no conflict with Christ being the same person of the Trinity while incarnate as he was from the beginning.
