God is both mortal and immortal, eternal and temporal.
-A8
"God is both mortal and immortal, eternal and temporal"
How can God in His intrinsic nature be both immortal and mortal, eternal and temporal? He is essential being, indivisible in His nature. Immutable so He cannot change from life to death, from good to bad. If God died then all of God died since God is one substance, indivisible.
