(3) City of God 21, 12: "Hence there is a condemned mass of the whole human race . . . so that no one would be freed from this just and due
punishment except by mercy and undue grace; and so
the human race is divided [into two parts]
so that in some it may be shown what merciful
grace can do, in others, what just vengeance can do. . . . In it [punishment] there are many more than in [mercy] so that in this way there may
be shown what is due to all."
(4) Epistle 190. 3. 12: He said that reprobates are so much more numerous than the saved that "by an incomparable number they are more numerous
than those whom He deigned to predestine as sons of the promise to the glory of His kingdom; so that by the very number of those rejected, it
might he shown that the number, howsoever large, of the justly damned is of no importance with a just God. . . ."
Which implies that God does not will all to be saved: hence Augustine's explicit denial, several times, of the words of 1 Tim 2:4. Hence too, as we said above, God does
not really love anyone: He merely uses a few to show mercy.

The human race is divided into two parts (meaning some predestined to heaven, and some predestined to hay-yull. )
This is "double predestination" - regardless of whether the exact TERM is used or not.
In contrast, Arminius says there is a CLASS of humans predestined to salvation -- the class of BELIEVERS - and that a person's free will IN
RESPONDING TO GOD's GRACE is what makes him a believer or not.
Calvin agreed with Augustine that "the human race is divided [into two parts]" - based on God's 'arbitrary decree' - not the will of the individual humans.
