Funny, I have been thinking on this very subject lately for whatever reason. Might be because I have been reading Augustine who wrote that God cannot sin or die. Anyway, I fully understand the concept of Christ having two natures but being only one person. That make sense. What I cannot quite grasp is the God nature dying, even though the person as a whole died. I have went over the Creed in my mind to try and settle it a little. Like Christ being God of God, Light of Light, Very God of very God, begotten not made. Which being the same substance as God the Father which is eternal. How does eternal have an end (in death) and brought back to life? There is a break in the eternal part there? Again, just thinking here. Then there is the scriptures that say, “ in him all things hold together”. (Colossians 1:17, ESV) and he upholds the universe by the word of his power”. (Hebrews 1:3, ESV), I would think that if Christ's God nature was dead for a second, all this would cease to exist. Either way, I will stick with the confessions' description on all this even without understanding. Those men were wiser than I will be.
