What does this mean and why is it in Denzigers sources of Dogma then:

"For, even if it were a matter concerning that subjection which is to be manifested by an act o f divine faith, nevertheless, it would not have to be limited to those matters which have been defined by express decrees of the ecuмenical Councils, or of the Roman Pontiffs and of this See, but would have to be extended also to those matters which are handed down as divinely revealed by the ordinary teaching power of the whole Church spread throughout the world, and therefore, by universal and common consent are held by Catholic theologians to belong to faith."

The act of subjecting the will to a doctrine is not limited to ONLY those things defined by the Popes and councils, but also to the ordinary magisterium, and consequently the theologians whose common consensus teaches what BELONGS to the Ordinary magisterium. And these are to be believed with Divine Faith, which things it is a mortal sin to deny.

This quote regards matters that are handed down as "divinely revealed". We know that Divine Revelation ended after the last apostle died, so apart from the infallible dogmas that contain the Deposit of Faith, this quote also refers to those definitive doctrines (secondary truths) proposed by the Magisterium in a "definitive way" which are strictly, intimately, and historically connected with what has been " divinely revealed", and that must be firmly accepted and held with Divine Faith. Theologians works have merit as long as they do not contradict these dogmas and doctrines. However, not every single teaching the Magisterium proposes has the same level of expected assent from the faithful. There are ordinary magisterial teachings the faithful owe religious assent, which is different from assent of Faith (Assensus Fidei).

Yes and we owe an act of divine faith to what theologians teach is the ordinary magisterium.

Here you've completely got it jumbled up.
