Like Baius Jansen refused to recognise that in the condition of innocence, in which man was constituted before the Fall, he was endowed with numerous gifts and graces, that were pure gifts of God in no way due to human nature. Hence he maintained that by the sin of our First Parents human nature was essentially corrupted, and man fell helplessly under the control of concupiscence, so that, do what he would, he must of necessity sin. There was therefore in man an irresistible inclination impelling him towards evil, to counteract which Grace was given as a force impelling him towards good, with the result that he was drawn necessarily towards good or evil according to the relative strength of these two conflicting delectations. It followed from this that merely sufficient grace was never given. If the Grace was stronger than the tendency towards evil it was efficacious; if it was weaker it was not sufficient. Yet, whether he acted under the impulse of Grace or of concupiscence, man acted freely, because, according to Jansen, absence of all external pressure was all that was required to make an act free and worthy of praise or blame. The book /Augustinus/ created a profound sensation among theologians. It was hailed as a marvel of learning and ability by those who were still attached secretly to the school of Baius as well as by the enemies of the Jesuits. A new edition appeared in Paris only to be condemned by the Holy Office (1641) and by Urban VIII. in the Bull, /In Eminenti/ (1642). Various difficulties were raised against the acceptance of the papal decision in Louvain and in the Netherlands, and it was only after a long delay and by threats of extreme measures that the Archbishop of Mechlin and those who followed him were obliged to submit (1653).
