If I told you that you are existing in three states simultaneously, would you believe me? [You are, BTW.] ... How is the Trinity reality of God any more difficult to comprehend? A scientific explanation of thr three states of existence happening simultaneously would not have been possible until within the past fifty years! That early believers whom we late comer Christians will meet where/when lost no sleep over the nature of God in Three persons—Blessed Trinity seems to dismiss arguing over the issue as if salvation depended upon it.
Ummmm, yes, I do think that 3 Persons who are One is essence is very difficult if not impossible for the human mind to comprehend. We as Christians accept it by faith, and our descriptions at best can outline or summarize it; be it three states simultaneous in matter or three parts of an apple or 3 leaves of a clover, or the innumerable imperfect analogies people have looked to, to try to capture the nature of the infinite God in their minds, down through the centuries.
It is an historic fact though that before Nicea Christians wondered, argued, and searched the scriptures about the nature of God and the nature of Jesus Christ, among other things we take for granted today—and like I said in my original post, I’m not sure any of the Fathers before say AD 250 had worked out these important doctrines yet. Does that mean they were somehow intellectually or morally inferior, or not Christians? Of course not. Only that doctrine itself took some time to develop—as Church scholars better understood—and were better able to describe—the revelations of God in the bible.
My only point was that the author of the article was seeking support for pre-Millennial end-times view (which has only existed in modern days since about 1830) amidst very early church Fathers—who didn’t yet see things clearly on some very basic things like Trinity (or the Homoousious). Better to look to scripture itself (like Athanasius did when describing God as Trinity) NOT what the earliest Church Fathers—as blessed as they indeed were—thought and taught.
