Orange was ratified by Boniface II and thus enjoys ecumenical authority. It is not a purely local synod. And the Tridentine Fathers had the decrees of Orange in front of them.
I went back to the Latin on this Council because I was seeing some strange variation in translations used to buttress the argument of contradiction. VERY different implications here.
Canon 8: "the free will of all men has been corrupted" [some have "weakened"].Check the Latin yourself. Free will in Orange is:Canon 13: "The freedom of will that was destroyed in the first man can be restored only by the grace of baptism". [Yikes!..didn't Trent say anathema to those who said the free will was destroyed?]
Conclusion: "the sin of the first man has so impaired and weakened free will that no one thereafter can either love God as he ought or believe in God or do good for God's sake, unless the grace of divine mercy has preceded him"
Canon 8: "esse vitiatum" = was damagedYou know why we still insist on Latin? This is why. So we don't get people trying to pull the wool over everyone's eyes with massaged translations. Orange said exactly what Trent repeated 1000 years later.
Canon 13: "infirmatum" = weakened, enfeebled
Conclusion: "inclinatum et attenuatum" = bent/changed/diminished and reduced/weakened
One does not have to go to a theology grad school student. I have found these comments on Freepers.
As for your Latin I would suggest a study of the entire canon, not just one tiny section that I can't match. For example, you say:
Whereas Canon 8 says:
Now I'm not sure what part you're refering to but the scripture is very clear unlike the Council of Trent that used no scriptural references. The entire point of the canon is that no one can come to the Father unless the Holy Spirit calls them.
