The references are all from Scripture. Pretty sure nobody in the Catholic church thinks her teachings disagree with Scripture, or they wouldn't be there. The canons you mention are rejecting things taught by Luther. Maybe you think that Luther's teachings are self-evidently required by Paul's teachings and are the only possible conclusion from them, but everyone doesn't agree with you.

The people the article is addressing -- those who think that Paul corrupted Christianity -- are almost invariably Judaizers who come from one or the other cultic offshoot of Protestantism. A Catholic who rejects Paul is automatically at least a material heretic.

Luther's 'teachings' are Paul's teaching, straight up. That all don't agree is self-evident. The Lutheran Confessions doesn't have any doctrine not tied to the plain text of the scripture.

I love the list of the doctrine as well,

Belief in Jesus for eternal life

Righteousness by faith

Justification by faith

Forgiveness of sin through faith

Repentance
