/summa/FP/FPII/FP_Q10:
We must now consider the eternity of God, concerning which arise six points of inquiry:
(1) What is eternity?
(2) Whether God is eternal?
(3) Whether to be eternal belongs to God alone?
(4) Whether eternity differs from time?
(5) The difference of aeviternity, as there is one time, and one eternity?
(6) Whether there is only one aeviternity?
