I don't think you know what Jansenism is but it is the following condemned propositions:

That there are some commands of God which just persons cannot keep, no matter how hard they wish and strive, and they are not given the grace to enable them to keep these commands;
that it is impossible for fallen persons to resist sovereign grace;
that it is possible for human beings who lack free will to merit;
that the Semipelagians were correct to teach that prevenient grace was necessary for all interior acts, including for faith, but were incorrect to teach that fallen humanity is free to accept or resist prevenient grace; and
that it is Semipelagian to say that Christ died for all.
