Cap. IX Arg. 1: major — sin's relation to damnation same as to reprobation; wisdom would not reprobate without demerit
They take the Major as clear from this: whatever relation sin has to damnation, it has the same to reprobation — so as sin is granted meritorious and moving cause moving God to damn this or that particular person, it must likewise stand toward reprobation. They add that it clashes with divine wisdom to will to reprobate a sinner without regard to evil merits, yet refuse to condemn him in time except for evil merits.
Latin
Majorem inde liquere putant, quod quam rationem peccatum habet ad damnationem, eandem etiam habeat ad reprobationem: atque idcirco sicuti agnoscitur habere rationem causae meritoriae et moventis ipsum Deum ad damnationem hujus vel illius singularis personae, ita etiam se habere debet ad reprobationem. Hisce omnibus adjiciunt, repugnare Divinae sapientiae, ut velit reprobare peccatorem sine meritorum malorum consideratione, et tamen eundem in tempore nisi propter mala merita nolit condemnare.
