On the contrary, the detractors of Jansen argued that the doctrine of the Augustinus [or, what they said it was] wasn’t the one of St Augustine. Two examples of it in:
[Translation: The true sentiments of St Augustine and of the Church about the grace]
[Translation: The sentiments of St Augustine about the grace, opposed to the one of Jansen]
The titles of those books are quite clear, and if you are unsure, just consider the summary of the first one, e.g.:
Chap. III: Éclaircissment de quelques passages de S. Augustin dont abusent ceux qui veulent lui faire dire contre sa pensée que Jésus-Christ n’est pas mort pour tous les hommes.
Finally an other quotation from the Refutation des critiques de Monsieur Bayle sur Saint Augustin (1782), by the jesuit Charles Merlin:
L’Augustin de Jansenius n’est qu’un centon composé de plusieurs textes de Saint Augustin pris à contre-sens.
Translation: The Augustine of Jansenius isn’t anything else than a mingle-mangle of Saint Augustine’s texts in the wrong sense.
