Cap. IX Arg. 3 Sol: physician analogy — command to preach to all does not prove God decreed to free all efficaciously
In a word: from God's will that every physician do his utmost — prepare and offer each patient he takes on whatever helps prolong life — you may not infer that God will let none die of disease unless he foresaw him a stubborn scorner of the offered medicine. So from God's command that Gospel ministers preach the word (the medicine of souls) to all, and strain every nerve that every one be freed from death, it does not follow that God himself decreed to free all from death efficaciously — or that he did not decree to permit some, by their hard hearts, to rush into perdition whom, had he not reprobated them, he both could and would have softened by special mercy. Vain, then, to judge the predestinating or reprobating will — which determines an effect by infallible divine action, or withholds it — from the mandating will that ought to govern human actions.
Latin
Ut verbo absolvam, sicuti ex eo quod Deus vult omnes medicos pro sua virili ea agere, parare et offerre cuilibet aegroto quem curandum suscipiunt, quae ad vitam ejus producendam conducunt, non recte infertur Deum nolle permittere ut vi morbi ullus extinguatur, nisi exinde quod eundem praeviderit ut medicinae oblatae praefractum contemptorem: sic ex eo quod jubet Deus ministros Evangelicos verbum (quod est animorum medicina) omnibus praedicare, et omni ope eniti, ut omnes et singuli a morte liberentur, non sequitur, ipsum Deum decrevisse omnes a morte efficaciter liberare, aut non decrevisse permittere quosdam sua duricordia in perditionem ruere, quos nisi reprobasset, et potuisset et voluisset speciali sua misericordia emollire. Frustra igitur ex voluntate Dei mandante, quae actiones humanas debet gubernare, de voluntate Dei praedestinante aut reprobante judicatur, quae effectum aliquem producendum infallibili actione Divina, aut ea negata non producendum, determinat.
