No. And I guess I am confused because the principles of Rerum Novarum and Centesimus do seem to get quite specific and are in the magisterium’s specific domain. Principles such as the fundamental rights of workers to form trade unions and earn wages sufficient to support himself, his wife and his children, state care and protection of the poor, etc, etc.
I do not understand the pope. He says it is part of the responsibility of Pastors to give careful consideration to current events in order to discern the new requirements of evangelization. And speaks of the social teaching as an essential element of the “new evangelization”. Yet he follows with the words you quote that such an analysis is not meant to pass definitive judgements since this does not fall per se within the Magisterium’s specific domain.
So pastors, including himself in this and Leo’s encyclicals, are required to do this analysis that will pass no definitive judgements. It sounds like he is undermining the social teaching authority.
Thanks for that confirmation and further explanation. As I see it, Michael, (and I am no Aquinas) you may be looking too deeply for the pope’s meaning in a case where he meant to be taken at face value. I generally believe as you do,"… the PRINCIPLES [my caps] of Rerum Novarum and Centesimus do seem to get quite specific and
are in the magisterium’s specific domain."
That’s why he added the reminder that he did not mean he necessarily was more qualified and competent in the myriad specifics of secular government than competent lay authorities. And the operative word is “principles.” A principle, while, basic, is only a general truth or law. E.G., Workers have a general right to form trade unions, but that hardly means that a bishop whose heart is with the workers is thereby competent to demand of owners, on pain of damnation, that the owners grant unions everything unions demand. That a truth may be both basic and general at the same time may be what confused you. (I dearly loved the man, but his writing style, or at least translations thereof, sometimes made me dizzy.)
He was saying that in secular matters a pope or bishop can propose, but he must allow the competent secular authority to dispose. That is, in secular matters render onto Caesar the things (specifics) that are Caesar’s, but to God the things (moral, principled lives and actions) that are God’s.
Still, the pope did not say pastors are required to do analysis that will pass no definitive judgements. Our non-Catholic friends (and some of my Catholic friends as well

) would love that. On matters of faith and morals pastors of course are required to make definitive judgements. That’s what he meant by “…within the Magisterium’s specific domain.”
The pope simply was reminding Catholics of the principle that no pastor should ever make a politically partisan, definitive judgement such as, “Catholics have to come together on issues like the Ryan budget because the ideas from the tea party and Fox News are profoundly worldly, secular and un-Catholic. It is ripping us apart.”
