Hi Quix! It is a very ancient insight, predating the Incarnation by some five centuries, that for there to be a universe, there needs to be two things (or rather, two underlying principles): that which stays ever the same, and that which is capable of changing. The insight is as old as Heracitus, the great Greek philosopher of permanence and flux. The insight is directly analogous to the first and second laws of thermodynamics: i.e., (1) the conservation of matter/energy, and (2) the law of (increasing) entropy.
What does not change in our universe is the Logos: the Alpha and Omega -- the beginning of all that there is; and its teleology, or end, purpose or goal. Other than that, everything changes; evolution under law can be accommodated. Which is why I do not accept that evolution is a "random" process. What is under law cannot be said to be developed randomly.
I'm not sure I've expressed this very well. If not, I'll hear from people I'm pretty sure!
Thanks so much for writing, Quix!
Thanks for the ancient perspective and insights.
I think the popular notion of Darwinian evolution is bankrupt wholesale but that's another issue, topic.
I think that the FOUNDATION/substrate/fabric of reality
THAT GOD IS
IS ABSOLUTELY necessary for the diversity and the changes in diversity that we observe. Otherwise, diversity would be too diverse to collect into recognizable clusters of anything.
Kind of like on another thread . . . infants need the stable security of parents and being held lots by parents . . . in order to explore and expand, GROW in diverse ways.
