Antonius Walaeus admits middle knowledge, proving it from Matthew 24 (days shortened; the elect not deceived)
Antonius Walaeus, professor at the University of Leiden, is especially notable. He acknowledges in God a middle knowledge by which future things are known on a hypothesis, even though they are not absolutely future, or not yet.
He holds, for example, that God foreknew that Adam would misuse his freedom if God made him such as he was, endowed him with such gifts, allowed him to be tempted, and so on. The same holds, he thinks, for the other outcomes of free choice that depend on the choice of angels or human beings.
He proves this knowledge from the passages of Scripture cited above and from many others, such as Matthew 24: 'Unless those days had been cut short, no flesh would be saved', and 'if it were possible, even the elect would be led astray', that is, unless they were preserved by special grace. From these and similar passages, he says, it is clear that God has some such knowledge, before any decree of his, of what was certainly going to happen.

XXVIII. Praesertim vero Antonius Walaeus in Academia Leydensi Professor agnoscit in Deo scientiam mediam, qua ex hypothesi res futurae cognoscuntur, etsi absolute futurae non sint, aut nondum sint. Et censet, verbi causa, Deum praescivisse Adamum sua libertate esse abusurum, si Deus eum talem conderet, donis ejusmodi ornaret, tentari permitteret, &c. & rem sic se habere de caeteris liberi arbitrii eventibus, ex Angelorum aut hominum arbitrio pendentibus. Atque hanc suam scientiam probat iis Scripturae locis quae supra citata sunt, & pluribus adhuc aliis, ut quod legitur Matthaei capite vigesimo quarto. Nisi abbreviati fuissent dies illi, non fieret salva ulla caro, Et si fieri posset seducerentur etiam electi, id est, nisi singulari gratia praeservarentur. Ex quibus & similibus locis manifestum esse dicit dari talem aliquam scientiam in Deo, ante omne decretum ejus, de eo quod certo futurum fuit.
