I think you miss the point. Even if nothing has changed and your perfectly correct nothing has changed but if these reflections and opinions are widely accepted and put into practice then its going to lead the faithful into believing it has changed and that is detremental to the souls of the faithfull. I surely need not remind you of the warnings of our lady of fatima or the multitude of visitations of our lady or our lords words "do you think i shall find faith"
I did not miss this point, I merely abbreviated it with the phrase
"It is unfortunate that the Pope has made such reflections and opinions as it has caused confusion and perhaps even scandal". Thanks for expanding my point into more detail.
There are some nuanced considerations in this debate concerning the "diminish culpability" of the couple. I would say that even if diminished culpability, which is a condition the Church teaches about the qualifications for mortal sin, applies to the couple, it only refers to the sin, not the ontological fact that they are living in sin if they continue to have sex without first receiving a Decree of Nullity. And, if diminished culpability does exist, that should be removed by education and counseling allowing the couple to have full and unimpaired knowledge of the teachings on marriage.
None of this, however, speaks to the ontological fact that such a couple is in an adulterous relationship if they continued to have sex, and thus cannot receive communion.
I think you are right that these reflections will likely lead to bishops and priests to practice what has not actually be legislated leading to more scandal, as well as spiritual harm to the couples.
We must pray that these issues get clarified. We must resist the idea of a so-called change in the doctrine of marriage (which, by the way, is a infallible teaching, Level 2 teaching, I believe).
We must approach the Pope's Exhortation (which is not a magisterial document) with critical analysis as mentions by Cardinal Burke:
Cardinal Burke says Pope’s exhortation must be read ‘critically’
And if there is an actual attempt to change doctrine, that must be resisted respectfully:
Cardinal Burke: ‘I will resist’ the Pope should he contravene doctrine
