... time ... is finite yet without boundary.
This universe could be everything—all there is.
Warren, your definition of time as that which is both finite and infinite, concurs with the GOD-hypothesis which makes sense to me, in my opinion and at this point.
I say the above because, unlike the Pope, I do not claim to be infallible in matters of "faith and morals".
BTW, I like to think of GOD and the absolute as one and the same. The word absolute, used as an adjective, refers to that which is whole and complete, and cannot be compared to anything else. This why I like to say: GOD simply is!
Philosophically speaking, GOD, IMO, is the absolute. In other words, GOD is not a being which is relative to other beings. Any god which is relative to other gods is, like them, an idol. GOD is without limits or restrictions; is that which is the ultimate ground of all things and is neither subjective or objective.
From philosophy and psychology we learn that our minds cannot know what things really are, of themselves. We only know them, and be conscious of them, by the effects they produce upon our minds as we sense how they relate to one another.
And speaking of relativity, interestingly, the article on Einstein, in World Book encyclopedia says that though he was not associated with any organized religion, "Einstein's nature was deeply religious. Merely to come into his presence was always a profoundly spiritual experience. Although he felt that belief in a personal God was too specific to the Being at work in this universe, he never believed that the universe is one of chance or chaos. The universe to him was one of law and order. He once said, 'God may be sophisticated, but he is not malicious.'" Paul Arthur Schlipp.
