Cap. IX Arg. 10: if election and reprobation hang on mere liberty of will, Gospel preaching to the reprobate becomes from God's precise intention a ministry of condemnation
If we set election and reprobation as hanging on mere liberty of divine will — not on the differing acts of elect and reprobate themselves (these penitence, those impenitence; these persevering faith, those final unbelief) — then Gospel preaching toward the reprobate, from God's nearest precise intention, will be a ministry of condemnation, and will not be set before them from God's first intention to work their salvation, but as a medium subordinated to damnation in executing the reprobation decree. That fights the Gospel ministry head-on, since from God's first intention it is a ministry of life.
Latin
Si ponamus electionem et reprobationem ex mera libertate Divinae voluntatis pendentem, et non ex discriminatis actibus ipsorum electorum et reprobatorum (puta horum poenitentia, illorum impoenitentia, horum fide perseverante, illorum finali infidelitate): tum Evangelii praedicatio quoad reprobatos ex proxima et precisa Dei intentione erit ministerium condemnationis, et non proponetur ipsis ex prima Dei intentione ad salutem ipsorum operandam, sed ut medium exsequendo decreto reprobationis damnationi subordinatum. At hoc directe cum ministerio Evangelii pugnat, utpote quod ex prima Dei intentione est ministerium vitae.
