Which of these teachings, if any, require "religious submission of will and intellect?" (Obsequium Religiosum)

  1. Teaching on cooperation with evil
  2. The principle of Double Effect
  3. The criteria for recognizing divine revelation (scroll down to the “Criteria of revelation” section)

Or perhaps at least one of these is actually infallible, thus requiring “full assent of faith?”

RE:

  1. Teaching on cooperation with evil

Comment: A bartender for example has the obligation not to serve a customer he views as inebriated. If he continues to serve that person, he could be legally liable for the collateral damage that inebriated person does. That’s not only true legally in our system of laws, but also a religious truth

  1. The principle of Double Effect

Comment: It’s never permissible to do evil that a good might come from it. 1761

  1. The criteria for recognizing divine revelation (scroll down to the “Criteria of revelation” section)

Comment: ccc.scborromeo.org.master.com/texis/master/search/?sufs=0&q=divine+revelation&xsubmit=Search&s=SS

all of these require continual effort on the part of every individual to do the right thing

This is at least theologically certain and seems to be proximate to faith as it is ascertained by various passages in Sacred Scripture. Cf. 2 Jn. 1:11, Prov. 22:24 etc.

  1. The principle of Double Effect

I would say either common opinion or theologically certain.

  1. The criteria for recognizing divine revelation (scroll down to the “Criteria of revelation” section)

This is strictly of faith, as defined by the First Vatican Council (1869-1870):

If anyone says that divine revelation cannot be made credible by external signs, and that therefore men and women ought to be moved to faith only by each one’s internal experience or private inspiration: let him be anathema.

The principal of double effect is not anything particularly fundamental. It it really a tool to help in the interpretation of the the 3 fonts of morality. [It is often poorly expressed too.]
