The first of the five propositions, in Jansenius's sense
Thesis XVI. From this, as from what was brought forward earlier, it is plain in what sense Jansenius maintained this proposition: 'Some of God's commandments are impossible for righteous people who will and strive, given the strength they now have; they also lack the grace by which they would become possible.'
This is the first of the five propositions just mentioned, which the Roman pontiffs condemned some years ago as maintained by Jansenius, and indeed, as they put it, in the sense in which he maintained them, though they neither explain nor define the sense they mean to condemn.
Latin
XVI. Ex quibus, ut ex iis quae superius allata sunt, manifeste colligitur, quo sensu a Jansenio asserta fuerit haec propositio. Aliqua Dei praecepta hominibus justis volentibus & conantibus, secundum praesentes quas habent vires, sunt impossibilia: deest quoque iis gratia qua possibilia fiant. Quae est prima jam dictarum quinque propositionum, quas ante annos aliquot damnarunt Romani Pontifices, ut assertas a Jansenio, & quidem, ut dicunt, in sensu quo Jansenius illas asseruit; quanquam sensum illum quem damnare intendunt, non explicent, neque determinent.
