I deleted my message since it assumed something that wasn't clear.

Do you mean section 5, where it states:

The teaching of the Lutheran churches presented in this Declaration does not fall under the condemnations from the Council of Trent. The condemnations in the Lutheran Confessions do not apply to the teaching of the Roman Catholic Church presented in this Declaration

As far as I can tell the doctrines laid out in the declaration, particularly those in sections 4.1 and 4.3, truly don't fall under the condemnations of Trent, particularly canon 9. Interestingly enough, though, the document contains this passage related to how we understand our cooperation in justification:

"Where, however, Lutheran teaching construes the relation of God to his human creatures in justification with such emphasis on the divine 'monergism' or the sole efficacy of Christ in such a way, that the person's willing acceptance of God's grace - which is itself a gift of God - has no essential role in justification, then the Tridentine canons 4, 5, 6 and 9 still constitute a notable doctrinal difference on justification" (PCPCU 22).

I don't see that understanding of cooperation or justification in the joint declaration though. From 4.1:

20.When Catholics say that persons "cooperate" in preparing for and accepting justification by consenting to God's justifying action, they see such personal consent as itself an effect of grace, not as an action arising from innate human abilities.

21.According to Lutheran teaching, human beings are incapable of cooperating in their salvation, because as sinners they actively oppose God and his saving action. Lutherans do not deny that a person can reject the working of grace. When they emphasize that a person can only receive (mere passive) justification, they mean thereby to exclude any possibility of contributing to one's own justification, but do not deny that believers are fully involved personally in their faith, which is effected by God's Word.
