Cum occasione

Cum occasione is an apostolic constitution in the form of a papal bull promulgated by Pope Innocent X in 1653 which condemned five propositions said to have been found in Cornelius Jansen's Augustinus as heretical.

The five errors of Jansen on Grace condemned in Cum occasione are:


 * 1) "Some of God's commandments are impossible to just men who wish and strive to keep them, considering the powers they actually have; the grace by which these precepts may become possible is also wanting to them."
 * 2) "In the state of fallen nature no one ever resists interior grace."
 * 3) "In order to merit or demerit, in the state of fallen nature, we must be free from all external constraint, but not from interior necessity."
 * 4) "The Semi-Pelagians admitted the necessity of interior preventing grace for all acts, even for the beginning of faith; but they fell into heresy in pretending that this grace is such that man may either follow or resist it."
 * 5) "It is Semi-Pelagian to say that Christ died or shed His blood for all men."

Bernard Otten explained, in A manual of the history of dogmas, that the first four of these propositions are absolutely condemned as heretical; while the fifth is condemned as heretical when taken in the sense that Christ died only for the predestined.
