City of God

And now that we have exploded these cycles which were supposed to bring back the soul at fixed periods to the same miseries, what can seem more in accordance with godly reason than to believe that it is possible for God both to create new things never before created, and in doing so, to preserve His will unaltered? But whether the number of eternally redeemed souls can be continually increased or not, let the philosophers themselves decide, who are so subtle in determining where infinity cannot be admitted.

For our own part, our reasoning holds in either case. For if the number of souls can be indefinitely increased, what reason is there to deny that what had never before been created, could be created? Since the number of ransomed souls never existed before, and has yet not only been once made, but will never cease to be anew coming into being. If, on the other hand, it be more suitable that the number of eternally ransomed souls be definite, and that this number will never be increased, yet this number, whatever it be, did assuredly never exist before, and it cannot increase, and reach the amount it signifies, without having some beginning; and this beginning never before existed. That this beginning, therefore, might be, the first man was created.
