Cause of damnation in humans themselves
Reprobation is the just sentence of Gods judgment upon all impenitent unbelievers. First, the fault is not the Fathers. For He sent His Son into this world not to judge it but to save it. By right, according to the rigor of His justice, He could have sent His Son to judge and condemn the world for sins against the law, because the whole lies in evil: yet from sheer grace He first sent Him not for judgment.
The proximate and chief cause of damnation is in humans themselves. The Lord does not speak simply of habitual and innate unbelief, but of actual, affected, obstinate unbelief joined with perpetual impenitence. This is the head of all sins, which God by His justice and truth cannot but condemn. The reason is that they do not believe in the name of the only-begotten Son of God: outside which name there is no salvation.
From all this it is plain that love of darkness and hatred of light — the proper cause of humans judgment and damnation — is to be sought only in themselves. See the excellent theologian Dr. Johann Bergius in his explanation of the saying So God loved the world, on the causes of human salvation and damnation, published at Berlin in 1629.
CHAPTER TWO follows, on the grace of redemption.
Latin
Reprobatio vero est iusta sententia iudicii Dei in omnes impoenitentes infideles. Primo, culpa non est Patris. Nam Filium suum in hunc mundum misit, non ut eum iudicet, sed ut servet. Iure quidem, secundum rigorem iustitiae suae, Filium suum mittere potuisset ad iudicandum & condemnandum mundum ob peccata in legem, quia totus in malo iacet: at ex mera gratia ipsum primo misit non ad iudicium. Causa proxima & princeps damnationis est in ipsis hominibus. Dominus non loquitur simpliciter de incredulitate habituali & innata, sed de actuali, affectata, contumaci cum impoenitentia perpetua coniuncta. Haec vero est caput omnium peccatorum, quod Deus per iustitiam & veritatem suam non potest non damnare. Ratio est, quia non credunt in nomen unigeniti Filii Dei: extra quod nomen nulla salus. Ex quibus omnibus manifestum est, amorem tenebrarum & odium lucis — causam propriam iudicii & damnationis hominum — non nisi in ipsis quaerendam esse. Vide eximium Theologum D. Iohannem Bergium in explicatione dicti Sic Deus dilexit mundum, de causis salutis & damnationis humanae Berolini 1629 edita. CAPUT SECUNDUM sequitur de gratia redemtionis.
