Cap. 6 Arg. 5: Absolute liberty of God in first-grace—Matt. 20 and Rom. 9
First, absolute liberty of God in giving first grace then shines out—an attribute everyone must acknowledge here. "I choose to give to this one as to you," even when human merits are unequal, is God asserting his own liberty (Matthew 20:14). And "I choose to give to this one, and not to you," where on the human side everything is equal, is a voice just as worthy of God, and likewise serves to display his supreme liberty, as Paul proves (Romans 9). For although by the power and efficacy of Christ's death God willed himself bound to give remission to believers, and glory to the regenerate grafted into Christ, yet he did not will himself bound—by any act of theirs, or any disposition of theirs considered in corrupt nature outside Christ—to give the Gospel to these nations or these particular persons, or to give faith and efficacious grace to these definite individuals. So those who teach that grace is given or denied according to the good or bad use of nature diminish the divine liberty God reserved for himself: which is as much as to say that nature anticipates grace.
Latin
Primo, inde elucebit absoluta libertas Dei in primae gratiae collatione: quod Divinum attributum hac in re est omnibus agnoscendum. Volo huic dare sicut & tibi, etiam in disparibus hominum meritis, Dei vox est libertatem suam sibi asserentis, Matth. xx. 14. Sed & illud, Volo huic dare, & non tibi, ubi omnia ex parte hominum paria agnoscuntur, aeque Deo digna vox est, & pariter spectat ad illustrandam Dei supremam libertatem, ut Paulus probat Rom. ix. Nam quamvis Deus virtute & efficacia mortis Christi ad dandam remissionem credentibus, ac ad dandam gloriam regeneratis & in Christum insertis sese obstrictum esse voluit, tamen ad dandum Evangelium hisce nationibus aut hisce singularibus hominibus, aut ad dandam fidem & gratiam efficacem hisce determinatis personis, nulla eorundem actione, nulla eorundem dispositione in statu naturae corruptae extra Christum considerata, voluit sese obligatum. Imminuunt igitur eam libertatem Divinam, quam Deus sibi reservavit, qui docent gratiam communicari & negari hominibus pro bono & malo usu naturae: quod idem est ac si dicerent, Gratiam a natura praeveniri.
