Cap. IX Arg. 6 open: absolute reprobation not from foresight of final impenitence is said to cast perdition's cause on defect of grace — Corvinus
Those who set absolute reprobation not sprung from foresight of final impenitence cast perdition's cause not on the reprobates' own malice but on a defect of divine grace. That, they say, is too unworthy of God, who is always ready to add further grace if a man uses well what he has received. So not from reprobation but from a man's voluntary neglect it comes that he lacks grace or does not receive more — namely that he has made himself unworthy of eternal life (Acts 13:46), held the truth in unrighteousness (Rom. 1:18), and not received the love of the truth (2 Thess. 2:10–11).
Latin
Qui ponunt reprobationem absolutam et non ex praevisione finalis impoenitentiae ortam, illi causam perditionis rejiciunt non in propriam ipsorum reprobatorum malitiam, sed in gratiae Divinae defectum: At hoc nimis Deo indignum, qui semper paratus est gratiam ulteriorem addere, si homo bene utatur accepta: Non igitur ex reprobatione, sed ex voluntaria hominis neglectu accidit, quod gratia careat, aut quod majorem non accipiat, nimirum quod sese vita aeterna reddiderit indignum, Act. xiii. 46. quod veritatem in injustitia detinuerit, Rom. i. 18. quod non receperit amorem veritatis, 2 Thess. ii. 10, 11.
