Jansenius admits good works before justification, which the Protestants seem to deny
Thesis LIII. It is true that Jansenius nonetheless holds, with the Council of Trent, that a man can do certain good works before he is justified, and that not all the works done before justification are sins and displeasing to God.
The Protestants seem commonly to assert the opposite when they censure the canon of Trent that pronounces anathema on anyone who says that all works done before justification, in whatever way they are done, are sins.
Latin
LIII. Verum est quidem Jansenium nihilominus statuere, cum Concilio Tridentino, opera quaedam bona ab homine fieri posse, priusquam sit justificatus, nec omnia opera quae fiunt ante justificationem esse peccata, & Deo displicere. Cujus contrarium Protestantes videntur communiter asserere, censura sua notantes Canonem Tridentinum, quo anathema dicitur quicunque dixerit, omnia opera quae fiunt ante justificationem, quacunque ratione facta sint, esse peccata.
