Thesis XXIII. Moreover, toward the end of the last century and many years before Jansenius wrote, the doctors of Louvain likewise recognized no grace sufficient for a person's conversion except the grace that actually converts him.
They maintain that the help sometimes given to those who neither believe nor turn to the Lord is not sufficient for faith and conversion, because grace sufficient for conversion converts of itself, and grace that does not convert does not suffice. Justificatio of the censure against the Louvain Jesuits, chapter 16.
Latin
XXIII. Caeterum sub finem saeculi superioris, & pluribus annis antequam Jansenius scriberet, Doctores Lovanienses nullam quoque gratiam ad conversionem hominis sufficientem agnoverunt, praeter eam quae illum reapse & actu convertit. Affirmant enim subsidium quod aliquando administratur iis, qui neque credunt, neque convertuntur ad Dominum, non esse sufficiens ad fidem & conversionem, quoniam gratia ad conversionem sufficiens ipsa convertit; quae vero non convertit, non sufficit. In Justificatione censurae adversus Jesuitas Lovanienses capite 16.
